  • I ran some basic tests on the hygrometers to see if the linear scaling would be a problem. A link at the end takes you to a Twitter thread with pictures. The result was... mixed. It seems clear that the high end humidities are never attainable on the Taylor model nor the clock. They don't seem capable of reading past 80%. However, on the low end they were in better agreement with the other models. It may be that the linear-scale hygrometers are built so that they behave more linearly but I'm personally doubtful of that. I would personally avoid dial-hygrometers with linear scales. twitter.com/TechConnectify/status/1387791666183032834

    • @turboled totally true.... that's why adjustable wrenches are so popular... like the Bahco .. shifting Spanner (English/French wrench ) .. Stillson (tube wrench ).. parrot beak clamp.. Pipe Wrench Pliers.. etc etc....... and obviously the bits for screwdrivers.... the good kit's that come with the adapter and the "tubes" for the different nuts.... both in inches and millimeters... are the favorite gift for Father's Day over here...

    • @turboled Don’t forget track events. “100 meter dash” rolls of our tongues like nothing. Also, most liquid medication doses are given in milliliters now, and active ingredient content of virtually all drugs are given in milligrams. Metric is everywhere. We just don’t notice it where it’s already established.

    • Americans do use the metric system... For food Calories are based on metric units (1 gram of water, 1 degree Celcius/Kelvin). For electricity, watts, volts, amperes... all SI units! Gasoline engines cylinders are measured in liters and not cubic inches anymore! Now yankees just need to close the gap between to go from watts (power) to joules (energy) to work to force (N) and to mass (kg)

    • @Ramdileo. sys And how about the toolboxes... Here in Canada, 2 sets of wrenches, 2 sets of ratchet boxes, 2 sets of Allen keys... Double the tools for nothing! They always end up mixed up and sometimes one almost fits to the other but not enough to prevent stripping all your nuts and screw heads...

    • Fun facts Alec.... down here in Latin America everything is in Celsius.. yes simple.. simple... but if you go to a hardware store... and you need to make a hole for a 5 millimeters LED... well then you need a 5 millimeters drill bit.. right .. yes .. simple.. simple...... .. now if you need a screw or bolts and nut for that hole.... you must transform it to inches.. because the screws bolts and nuts here are in inches.. unless you want ... "the expensive ones" ... the "Europeans" one.. (because is also the European screws bolts and nuts).. aaaannnnd....... yes.... they are in millimeters.. and with different incompatible threads... Now if you want an authentic trip of back and forth between the metric and the English System.. Go to a bike store here (bikecycle or motorcycle is the same mess) and buy the stuff for build you self a wheel..... yes one of the "simplest machines".. the wheel... ..... then you have...... The Tire ... is on inches .. both the circumference and the thickness .. ok cool... The inner tire (the inner tube) ... is also in inches yes...... but.. if it have European air valve (Presta) then it is in millimeters... now if it have Schrader or Woods.... then is back to in inches..... Now The rim is on inches... circumference and the thickness.... but the air valve hole will be in inches or in millimeters according to the Inner tube that you have chosen before.... The spokes (tensioners) .. are in millimeters... but many people know them in centimeters..... Unless it's the new kevlar or carbon fiber one .... which.... yeap.... is back to inches.... Now the center mass... It is in inches ...... if it is with sealed ball bearings... but it is in millimeters if it is with Cup & Cone ball bearings..... and finally the axis.... with which you screw the wheel to the frame of the bicycle or motorcycle....... yeah that one is "European" ...... is in millimeters.. and with the incompatible threads with rest of the screws bolts and nuts you have around here...... and they say that "wheel and axle" ... is one of the "6 simplest machines".... :-D

  • I've unsubbed from wrenglestar for making fun of the metric system. I'm not saying you guys should embrace it but don't say imperial it's better at least.

  • Ok but what I want to know is how they pin a particular length to a percentage of humidity. I expect a 4 part video series shortly.

  • Man it’s 60 degrees in your basement?? And I thought *I* preferred cooler temperatures....

  • I still can't get over the fact that the green screen looks so ... real!

  • aha, the bimetal wire works only in F scale, explains why we have electronic versions in Czech to get C scale

  • Why don't you use a real unit of measurement like barrels?

  • NO! Don't do simple! People have gotten complacently lazy! Next thing you know they wanna know how they can be certain, there is no one behind the mirror!

  • This website I found lol

  • It's ok, simple is relative right?

  • All we need is a little compromise for imperial and metric to find a common ground. Base 12 metric. That way no one is happy!

  • I want a shirt like that

  • Is it possible to measure the dew point along with relative humidity? That would be more accurate.

  • The absence of ending credits made me forget to say something about the metric system and I'm going to complain about the ending credits instead :-p

  • The guy who made Fahrenheit wanted to be able to have a measure of temperature that didn't need fractions. IMO I'd keep F regardless.

  • Do one about CCD and cmos

  • "define conditions using those materials as a reference" almost like something like hmmmmm idunno freezing and boiling water maybe? ;)

  • Whenever someone says "bimetallic", I never know whether they mean "twice a metal" or "once every other metal".

  • 👍👍

    • obligatory jokes about your primitive measurement system. 🤣🤣 😉😉

  • I hereby claim Bimetallic Strip Tease for my band's name.

  • I was listening to this while working, when it got to the end I was like wtf??!!!

  • 2:47 Ynow, if it is that easy, why don't YOU do it? Please, it's a joke, don't @ me.

  • I actually watched the whole video and I really like your channel!

  • It's 2021, let's stop using these other silly units, Kelvin is the superior unit of temperature.

  • As always, very informative and entertaining, great job Mr. Señor.

  • I ha... dislike blue LEDs they put everywhere. Love number 43 though. My favorite :)

  • Had to like this video just for the F to C conversion rant!

  • Why didn't you add conversions to Kelvin? Everyone knows that's the /real/ scale...

  • 2:07 Snark level just went off the charts! Love it.

  • 0:00 - 0:15 Pretty much how CDPR made Cyberpunk.

    • Anyone else noticing how his hair has been slowly but surely growing from one video to the next?

  • I actually like F better than C because the units are smaller.....big difference between 20 and 25C. Everything else and metric is better.

  • the rant about your lame ass legacy scale ruined the video, just use titles and accept your problems

  • "The story grew in the telling."

  • "I'm not gonna use celsius, *go use google*." SMH. My first dislike and I've been watching you for years since CD.

  • And how much is 60 degrees Fahrenheit in thermobananas? By the way, why don't you call it a thermo-foot instead of a thermometer. Well, I think I have already said the obligatory jokes about your primitive measurement system. 🤣🤣 😉😉

  • I liked this channel more when it wasn't trying to be goofy.

  • @2:25 thank you for explaining to me how I can use modern technology to perform conversions _I wouldn't have to if you used sane units to begin with._ :D Note: I wouldn't have made this comment either, since I was under the impression that we're on the same page... but apparently you felt you had to _start shit._ ;]

  • Will you consider doing a video on how shitty modern washing machines are? You should partner with lorain furniture and washing machine in ohio. that dude is amazing. Check out his channel you will love it.

  • Not a good enough excuse to use the word "impregnated"

  • You should do a video on air fryers

  • Haven't seen this channel in a while. Did you lose weight? 🤔

  • You are so funny, but informative. I can watch any video by you.

  • is the next "simple" vid about wet bulb vs dry bulb measurements?

  • Simple indeed. You didn't even go over Latent Heat and the Refrigeration Cycle!!!

  • You are the hero the imperial system needs!

  • Anyone else noticing how his hair has been slowly but surely growing from one video to the next?

    • Must be the humidity!

  • As to C or F, Metric or Imperial ... etc .. you sir have a Thermo - METER .. You Have Hygro - METER, Etc and every other thig that counts shit ending in Meter, now let that sink in ;)

    • @dolita windo a parcel of air near saturation may contain 28 g (0.99 oz) of water per cubic metre of air at 30 °C (86 °F), but only 8 g (0.28 oz) of water per cubic metre of air at 8 °C (46 °F)., its a question of mechanics and ratios, a meter just like the one in the video but with both cogs connected, lets say we have 10g water at 30° is 70% and 30 is also very hot temperature, so, the colder it is, the more humid , so basicly temperature cog turns anti clockwise, forcing the humidity cog to turn clockwise, thus in an analog way represent the decreasing temperature and increasing humidity even if humidity stays at 10g per cubic meter, and having it in a way where if the humidity cog moves left or right by itself it does not change the temperature, just the other way around, we have bicicle gears, car gears, clocks, im sure there would be a way to do it

    • represent the relative humidity across a range of temperatures? Haaaaalp I can't sleep. I have to knowwwww

  • Not to be mean, but it makes me feel a little better that even big, million plus sub channels have problems with watch time too. I'm happy when it says 40% of people watched one of my videos to the end.

  • Ta-da-da-daaaaa-da ta-daaaaa ~

  • I have a series of thermometers, hydrometers, barometers, and they all use those coils. I never even bother to look at them because none of them ever agree. They are more or less just decorations at this point. I sure would love to have an indoor/outdoor weather station that was accurate and trustworthy enough to be useful to me. I'm amazed that the weather station a mile from me, has been there since I was born; yet my phone can't give me an accurate reading of the current temperature outside. Say I want to buy a Thermometer/Hydrometer/Barometer that cost a little more than $0.03 to manufacture. What should I look for?

  • I can’t ‘thumbs up’ 👍 hard enough on this video for the remarks about Fahrenheit, not without breaking the screen anyway!

  • Speaking of measuring units: (and that's just about length 😄😄) pltools.info/it/qG-xjrSAyZxgu84/wideo

  • wrt temperature, I'm less annoyed by the use of weird units than I am by not specifying them at all "its 30 degrees out" - this means nothing to me. Is it hot or cold? "its 30 degrees Farenheit out" - ok, I may not know _how_ cold this is, but I do at least know that its not hot, and I now have everything I need to convert it to the clearly superior Kelvin scale. wrt humidity, honestly I think a scale that goes "dry", "normal", "humid", "very humid" is probably sufficient for most people.

  • Scotch T120. Oh how that takes me back.

  • **laughs in metric**

  • (F - 32) / 1.8 = C (C * 1.8) + 32 = F C + 273.15 = K [(F - 32) / 1.8] + 273.15 = K Are we good now? No? Nevermind

  • Hi dear, this is Jane, i would love to invite you to test PRTUKYT wireless headphone on your channel, are you interested? If so, pls let me know how to contact you, thank you in advance.

  • * sad nonexistently smooth jazz * :(

  • I was so looking forward to that sweet, sweet jazz outro 😢

  • Damnit! I want my temperature in Kelvin!

  • took me to eat a supermarket frozen pizza. Absolute perfection.

  • But...but...relative humidity depends on the temperature. Wouldn't the bimaterial strip or the numbered scale have to change from one temperature to the next? Or is the paper somehow responding in the same way somehow? Is the metallic strip changing based on the temperature and and the paper just conveniently responding in a way that lets you represent the relative humidity across a range of temperatures? Haaaaalp I can't sleep. I have to knowwwww

    • another arbitrary conversion. The Fahrenheit hate is completely unwarranted.

  • Ha-ha :) It is not difficult to use go9gle to convert scales. It's still annoying as almost the whole planet uses Celsius scale. It's also strange that USA being technologically advanced country still insist on using archaic measurement units.

  • How does my rear view mirror work. I can flip a tab on the bottom and it shows a darker reflection at a different angle.

  • "and dad jokes" finally.

  • maybe if people who use a decent measurement system always bullied every united statian about the use of correct measurement systems, maybe, just maybe they will collectively change.

  • If you saw the digital one I had, you would know the meaning of inaccurate. Lol. Not all digital ones are good. All of my other analog ones, read closer to the actual humidity on the weather station, than this crazy digital one I have. It is consistently 20% different on the dry side, than anything else and the analog ones, like you said are about 10% give or take.

  • My problem with metric evangelists is that their big selling point seems to be that the measurements aren't arbitrary. This is ridiculous. The main selling point of the metric system is that everything is in units divisible by ten. Metric evangelists will tell you that Celsius isn't arbitrary because 0 is set to the crystallization point of water, and 100 is set to the boiling point of water. The problem is that the crystallization and boiling point of water are dependent upon the pressure of their environment. Water doesn't boil at 100C. Water boils at 100C when air pressure is at 1 Bar. Is there a low pressure front moving through? Your water will boil earlier and at a lower temperature. Why is 1 bar the "standard?" Seems pretty arbitrary to me. 1 bar of pressure has absolutely no fundamental relationship with the physical universe.

  • @1:50 Bimetallics: "This" may actually be of interest to you. Although I've understood the concept and practical utilization since I was a lad .. there was one ubiquitous application of Bi-met that happened to squeak by under the radar until I was three decades into electronics - stove burner "modulation" controls!! It just occurred to me one early morning some time ago that a 70's range sure as shoot wasn't using triacs to control temperature .. and indeed the controls are variable rate spring loaded bimetallic .. Like an old school auto indicator flasher, but with mechanically adjustable break tension (so technically electro-mechanical PWM) You could probably do an entire episode on Bi-mets .. Fluorescent starters, turn signal flashers, toasters .. they even made bulbs with internal flashers - they were an ingenious and simple solution to a myriad of problems before the age of micros.

  • I refuse to convert to metric I call it Communist Units

  • Why is it if you buy five electronic hygrometers none of them agree and can be way off from each other?

  • Always as entertaining as it is informative watching your videos, keep them coming, snark and all....

  • Ok, Loved the °F/°C "rant"! :D As long, as you at least display °C (or K to confuse all of us) I'm happy :) Oh and also: people with real units aren't used to use Google to convert :D

  • I see that you’re still using the none metric clock. Tsk tsk

  • That twitter crap is why i got off twitter. So freeing.

  • Defending Fahrenheit just because you grew up with it is the same as defending Star Wars prequels because you grew up with it. You feel more related to it, but it's still crap.

  • By the way, you can also use Google to convert between Centigrade and Celsius.

    • I'm rubbish at mental arithmetic but even I can do that one in my head!

  • 1:58 - I've been saying this for years. I'm happy to use Celsius for almost everything all day every day, but when it comes to the weather and its related temperature, I want it in Fahrenheit. The freezing and boiling points of water are not a useful point of reference in that application. Fahrenheit is indeed more pleasing. In fact, both of these units are arbitrary conversions of the true SI temperature unit, Kelvin. We use them specifically because Kelvin is kind of a useless scale for most applications. So as long as we're _already_ using arbitrary conversions to make things more convenient, why not acknowledge that Fahrenheit has its place and stop being elitists about Celsius? It's not like this is imperial measurements VS metric measurements, where metric is objectively superior and we're ridiculous in the US for not switching. This is just one arbitrary conversion VS another arbitrary conversion. The Fahrenheit hate is completely unwarranted.

  • Is my 20 dollar walmart water boiler the best way to boil water? You say that in England there water boils faster! What do they use?

  • always remember 28c = 82f

  • 2:04 here's a simple way to convert Celsius to Fahrenheit and back. A difference in one Fahrenheit is about 0.55556 Celsius or two Fahrenheit are 1.11111 Celsius. Knowing that 32 Fahrenheit are 0 Celsius and 212 Fahrenheit are 100 Celsius it's pretty easy to do the maths. 20 Fahrenheit are 11.11111 Celsius so 52 Fahrenheit are 11.1111 Celsius and 72 Fahrenheit are 22.22222 Fahrenheit and 92 Fahrenheit are 33.3333 Celsius. This is simple enough to give a rough estimate for the temperature as this is usually sufficient enough. Btw ever been pinned and be very happy about it :)

  • I hate Farenheit and I love your rant against the unsolicited metric milita, and now I'm having an existential crisis and I snapped like a poorly designed bimetallic strip.

  • What about psychrometers?

  • I was going to like it anyway, but liking for the conversion rant.

  • I can’t believe you did a video where you didn’t mention the latent heat of vaporization even once. Unsubbed!

  • That snark tangent - spot-on and precisely why our units are no sillier than anyone else's, especially temperature units

  • Had to run across the room to check my hygrometer linearity. She passed the test thank goodness.

  • well as a Canadian from near the border we are taught both so my brain thinks of temps in both also quick from c to times by 2 add 30 or f to c divide by 2 subtract 30 for a rough and quick temp conversions

  • Please do a video on how automatic train lights/gates work. Seems like just your type of video.

  • What temperatures was he talking about??

  • Hey, why not move to C? 🤔 😂

  • Do those plant soil moister readers work in a similar way?

  • You're as good at Celsius as I'm at Fahrenheit? Good to know you're fine with using Celsius everywhere. Turns out watching a bunch of Americans makes you also understand Fahrenheit.

  • I don't like the tangent about temperature conversion, specifically when you explicitly tell viewers what to do.

  • I always wondered why the humidity scale was non linear, thanks!

  • Congrats, you just convinced everyone unit trolling you to do it even harder. Rule #1 of counter trolling, trying to reason with trolling is pointless, it's unreasonable by definition. Rule #0 don't feed the trolls, and you just served people a free 24/7 all you can eat buffet - if you're trying to actually lessen it, that's not a smart move.

  • I bought one after you talked about it first.

  • In the UK, those of us of more advanced age tend to use Fahrenheit for ambient temperature and Celsius when we get nearer freezing temperatures. It's 'cause Fahrenheit is confusing at low temperatures. Ta.

  • This is not new-fangled. In the early 1980s my parents used to run a flea market stall in Australia, and I would go amongst the other stallholders buying crap. I remember buying a box of NOS aftermarket car gauges that included several boxed "thermometer + paper/metal hygrometers". I also remember wondering how they worked, since I knew how bimetallic strips worked :) Anyway, they were already old hat in 1984.
