I love the abrupt transition to Violet’s glowing watch.
I once looked up the price of gold. It was denominated in dollars per troy ounce. I wanted to know how much a troy ounce is.
**20 pennyweights. A troy ounce is 20 pennyweights. Of fucking course it is!**

The calorie is dogshit if you’re trying to do anything except heat water. It’s equal to 4.184 Joules, which is the actual metric unit of energy. Fuck Josh Bazell.
Lazy question: Why is pound shortened as lb? It makes things even more confusing!
They forgot to mention that this is true at standard temperature and pressure.
Except for the fact that, in science, America uses the metric system and has for a long time
I love how they’re throwing out moles like it’s a nice, clean number instead of 6.022*10^23
Calories and centigrade are not SI units (therefore only obliquely “metric”), and the mass/volume measurements only apply exactly at 4 degrees C (277.16 K). And hydrogen’s atomic mass is isotope dependent and not “exactly” one mole at that mass.
As fun as this all is, it really came about this way deliberately but not truly and entirely metrically.
Well there’s some dumb fucks here in The U.K. who are getting all orgasmic about pounds and ounces now we have left EU. So being stupid isn’t confined to USA
Isn’t it 1 BTU per gallon per degree farenheit?
Aren’t all of those comparisons only true for water? So, it is kind of arbitrary? Or does this relationship hold for all liquids/materials? Not to take away from the fact that the imperial/American system is dumb, but I don’t really think this example proves it.
Hydrogen does not have constant weight. It weighs differing amounts on the Earth and on the moon. Its mass, however is constant.
A calorie isn’t even a SI unit. It takes 4.18kJ to heat 1L of water by 1C, which is no nicer than the 8.79 KJ it takes to heat 1 gallon of water by 1f
To be fair, that’d also be how I’d answer it if the question were in metric because I don’t have latent heat enthalpy values memorized
The jokes are funny, however the circle-jerk bitch fest is showing its age.
Please show me anywhere in American science or industry where this still happens. I was forced to buy a metric wrench set in the 1980s like everyone else and we are quite familiar with both systems.
It’s funny that Europeans will speak three languages before lunch but have a fit that we use two measurement systems, one for science and another for more common stuff like baby weights and food.
People always shit on the Imperial system as somehow the dumbest thing ever invented, but they forget the system wasn’t designed for science. It was designed for trade and labor by people who did trade and labor.
See its not idiocy and insanity.
What is a yard? about the Length of an average person’s arm. Foot, again pretty explanatory. Inch, width of an average thumb. A pound? about what fits in about your first of most organic materials. Ton? How much a giant barrel called a, get this a ton, weighed when fully loaded with wet goods. What is a mile? About the distance you can walk in a 1/4 hour.
And it breaks down from there that everything is fractional. So even if somehow you ended up without measuring tools, you could “abouts it” with nothing more than your own body. The system was less the fixed exact measurements, but more about having a system that people learned so they could get work done using something as a standard of measure.
Of course the trouble here is obvious, which is standardizing it so your ounce of gold is my ounce of gold. But the same can be said for a meter which is decidedly NOT 1/100000th or whatever of the circumference of the earth. Its pretty well documented that original figure of the size of the earth they based a meter from was off by something like 20%. So a meter is effectively a “French yard.” at this point.
Boiling point of water? 100 degrees, but at where? Boiling point of water drops rapidly with elevation, and changes with humidity, even the local weather’s barometric pressure changes that enough to be measured.
Honestly if you want the two most immutable temperatures known to man that are still relevant to daily life? The freezing point of distilled water, and the core temperature of a healthy human at rest in a state of comfort. That said Fahrenheit should have used those…but got the human temperature wrong by 1.8 degrees, and for some reason decided to use the melting point of salted ice instead. But I degrees.
Metric is neat because its based around a bunch of science, an no doubt base 10 is easy to count/convert for us base 10 number system people… but its been slow to catch on with laborers because 10 divides by 2 and 5 and nothing else, and both are prime numbers to boot. 12 divides by 2, 3, 4, and 6. And 4 divides by 2, and 6 divides by 2, and 3. Also 12 doubles to 24 which is divisible by 2, 3, 4, 6, and 8, which brings us 8 which divides by 2, and 4.
Take something and half and half again, and you have 8ths. 8th’s don’t work as well with base 10, sorry what is 1/2 of 1/8th of 20 again?
To be frank there is a reason multiple civilizations in history counted in base 12, and our time scale is still base 12.
Its why you see American carpenters continuing to use Imperial unit tools to this very day. For their kind of work, its actually a bit more useful. (And yes most American tradesmen know how to also work with metric. Hell double sized tool kits are common here as well.)
The old imperial system is born out of people doing simple operations like halving, doubling, or quartering things as they sold goods or preformed labor. Its not quite the insanity the internet loves to mock.
Its by no means a perfect system, its sometimes quite cumbersome, but if you can do basic fractional math its quite useful.
But its the metric system, if I try to say anything other than Imperial was the WORST system ever devised by humans I’ll be hung in meters of rope. I fully expect to be downvoted by this almost instantly. And then comment bombed by people calling me every mean thing there is.
Now, can somebody tell me where my 10mm wrench went? Because contrary to what Europeans seem to think, anybody who isn’t brain dead knows how to use metric in the States.
Edit: I decided to google it, and apparently a gallon was also “the volume of 8 pounds of wine” as defined by medieval terms, so…yah.
Edit 2: ya’all can chill with the insult laden replies. I never said you should adopt imperial. Just explaining where it came from and why its not insane, arbitrary, and pointless. Enjoy your metric people, as a cheeseburger I use both interchangeably anyways, as MOST Americans do.
You can’t answer that question even with metric. You’ve misplaced any information about the starting temp or air pressure.
To be fair the above example neglects that to find the energy needed to actually boil the water you would need to include the definitely not base 10 number of 2260 kj/kg to truly bring it “to a boil” by vaporizing at least some of it
In the American system, the only people who would be answering this kind of question would be scientists, who already work in metric, and have for literally decades. In everyday life, you will never need to answer this question, which is why there is low motivation to change.
This isn’t true at all. The basic unit in imperial isn’t mass, it’s weight. So it doesn’t make sense to compare the units on density which is what the author is implicitly doing. One pound of water can be raised one degree Fahrenheit with one BTU of heat.
This is an absolute correct description. What is this from?
