Why the United States refuses to go metric

As more cars start featuring electric drive, it will get easier.

Yes. I always set traps like that.

Sure, “vast majority” can mean almost anything you want depending on where you make up the lines, but with a 40% margin of error at the bottom end, and a 15% margin of error at the top, I think we are struggling to even call it a clear majority.

This link is just a one-time snapshot of ‘highs’, but when we are up against an unprovable no-true-scotsman sort of claim, I don’t think it’ll make any difference to the substance of the argument either way.

As someone that has grown with the metric system I call bullshit on your arguments. Sure, there’s some stock on these measures but plenty of material has both metric and whatever it is you consider normal for your benefit only. Most of it is produced in China anyway, that couldn’t give 2 fucks about the measurements the clients prefer, you give the specs and they build it.

Just slap a fucking stamp with both measures on the material for the benefit of the older people and teach the kids metric. Transitions are exactly this: transitions. It will take two generations to get used to it (kids with parents that only understand royal measures and their kids that grew up living in a metric world).

Funny thing is that I could never learn royal because it’s so arbitrary and forces you to remember so many rules
 It’s just the difference of not growing up in the only culture that believes it’s better.

Even the name of the system (“Imperial”, or, with [certain variations] (Comparison of the imperial and US customary measurement systems - Wikipedia), US Customary) escapes you. Bravo!


which is as it should be. I was a young man when we switched from Imperial here. I don’t miss it. It was a mare’s nest of rather arbitrary definitions.

These are the stupidest arguments I ever heard:

“We think of halves and feet and thirds.” - I think in fifths, and I do not think in feet at all. When was the last time you measured anything with your foot?

Also, he says it is not scientific. That right, it is not, it is rational. because it is much easier to thing 10x10x10 then 3x6x12. And then use some compound units of measure, like pressure, and you’re in hell.

These things are obvious for everybody, and once you switched you never think about it anymore, but now, as you can see in here: oh, I am happy to use gallons, etc. Anyone remembers the british monetary system?

No one cares about horse power. How many times are you using that unit? You go everyday and say: may car has 200 HP?

Whereas Celsius is 0 where the water freezes, 100 where it boils, Which is way more rational to use and easier to calibrate. Granularity? We can use decimal points you know, 12.75 Celsius. I just cannot see why fahrenheit is superior for weather. Outside is 20, how much is that? I don’t know, I guess is cold. In Celsius, you say it’s -10, that means there’s ice. Pretty clear to me.

I wonder whether it’s really measurable, or you’re just feeling some psychosomatic effects. In any large enough room, there’s going to be some difference in temperature between where your climate control (whether that’s a heater or a cooler) outlet is, and the other side of the room. That difference is going to be much more than your skin’s sensitivity. To say nothing about humidity


Sounds to me like you’re feeling the difference because you want to feel the difference. Perhaps a double-blind test is in order? Maybe you should take Randi’s challenge?

You’re failing to think of every possibility.

What if, indulge me here, for some reason you need to know the outside temperature very precisely (say, the exact difference between 8.33 and 8.88 C / 47 and 48F) while simultaneously suffering from a medical condition that makes you averse to non-round numbers? Or maybe your thermometer was too cheap and it only shows two digits. What then, smarty pants? Farenheit saves the day, that’s what. Totally granular.

An ox, two oxen, a horse, two horses, a goat,


It all goes to the dogs when it runs up against British India and the Standard Acre, where 1 Acre can actually mean anything from 0.8 acres to 4


Which part of “India, China and Africa” do you need explained? Our summer temperatures can shoot up to about 40Âș-45ÂșC. Conversion to Funnyheit is left as an exercise to the reader.

Right. Or .308 Winchester or .22 long rifle. Not all ammunition is measured in metric.

And just to extra specific (yes. maybe even pedantic), 7.62x51 NATO is not the same as .308 Win despite having the same external cartridge dimensions. SAAMI/ANSI standards allow a higher pressure load in .308 Win.

And boy is it a bad idea to mix those up.

A younger me without as much sense had a revolver designed for .22 shorts. So of course I put .22 long rifles in it. They fit, if I ground the tips of the noses off.

Bullet fragments everywhere when I fired that thing. Never again.

Just one thing 0 centigrade is not based on the freezing point of water but waters triple point which remains steady over a much larger pressure range.

This could use an illustration.

Everything between the orange lines marked “subtropics” means places where you probably can live your whole life without having to deal with much sub-zero (C; “sub-32” F, you know, water-freezing) climate.

Change that ‘probably’ to ‘very, very probably’ in the areas marked in scorching red. That red area is around 40% of the planet’s surface and does not quite contain half the world’s population, but it’s getting there.

So yeah, the useful range of environmental temperature to quite a few people is more like a nice round 0 to 50C (32 to 122F) instead of -18 to 38C (0 to 100F). So appropriateness and ‘superiority’ is relative, etc.

I can’t believe any of this has the right to be that controversial.

I guess some measures are just more ingrained for specific uses. I’ve never really learned imperial, but I sure understand a 20 psi pressure difference in my bike’s tires better than the metric-but-not-SI 2.39 bar or whatever. Even though it’s printed right there in the same gauge. Granularity! Don’t get me started on kilopascal.

Likewise, I’ve read somewhere (maybe here) that the half-inch pitch bicycle chain standard will probably outlive us all since even the French gave up changing it long ago.

That is on par with the idiot who brought a snowball into congress, thinking it somehow disproved global warming.

I picked one of those countries right in that hotspot area, and got a yearly temperature graph for a city in that country, N’Djamena, Chad. Behold, science!

Most of the time, they are living within the 0F to 100F temperature range.

I’d say that they’re normally living in the 15° to 40° range (almost precisely, I’d say). Much, much tidier.
