Current Events > Hey 'mericans! If imperial is so great, why do you use metric to measure bullets

(+) Yeah! (+)

Isn't that literally what the other side is arguing, too?

People are going to prefer whichever they grew up with, that's natural.

That said, didn't Fahrenheit get standardized first? I see a lot of people act like the US just randomly made up Fahrenheit like 10 years ago to be different.

My take is that Fahrenheit allows for greater precision of temperatures within individual units rather than needing to split degrees. A difference of one or two degrees is more subtle in Fahrenheit than Celsius as a result. Celsius has an admitted advantage as 0 is easier to remember than 32 for freezing, but beyond that I don't view that alone as overcoming it's drawback over individual degrees covering too much of a range (and I don't credit 100 at boiling as a major positive, as you don't really use that in every day conversation as anytime you boil something you just it to boil and the water actually boiling is the cue).

This is sensible enough and we can work with it.

The difference in F is more subtle than C, sure.
My take is: does that even matter, if its i dunno 58 outside, maybe it is too warm, no idea honestly but lets just assume its warm, if you are out and about can you really tell when the temperature goes up or down 2 or 3 degrees? how much does it vary on a warm day from morning to noon and then to sunset? is that something that can be genuinely intuited?

Because if not, then I cannot see any argument on how F would allow for greater precision in practice because people cant really tell differences of individual degrees just like its useless to have decimals in C which is possible but not really practical or needed.

In terms of outdoor temperature, not so much, but in terms of vehicular or indoor temperature? Absolutely, a single degree or two difference is very noticeable if you're used to your car or house at specific temperature.

How so

Whats the difference from yoru house being comfortable

in my case it would be 25 C feels pretty fine.
After conversion that would be 77F
how does 76F or 78F feel?

Nope, the original post was "if X is so good then why does the military use Y"

Then someone brought up how natural F is for temps which got countered that C is just as natural for everybody else, its no an argument for why its better, just a counter to anyone that goes "F good cuz natural".

A single degree indoors is very noticeable, much less two. Granted, we have a good AC/heating system, but if my wife or kids shifted the thermostat by even a degree it'd be noticeable if the thing was running.

These are very easy to notice the difference in indoor temperatures.

So I have no way to really fathom what kind of scale you guys are using that can tell differences from by a single degree from warm to a hundred?

I've got an couple of AC units cause my town is super hot throughout the year. When I change it from 23 to 22 I dont notice it, I will notice if I change at least 4 or 5 degrees. in terms of outside temperature and even AC temperature.

Sounds super suss at the moment.

Most people in the USA cannot reliably perceive a temperature difference of a single Fahrenheit degree. Human perception of temperature changes is generally less precise, with studies suggesting that noticeable differences typically require a change of about 24F (12C) under normal conditions. This varies based on factors like individual sensitivity, humidity, wind, and the context (e.g., indoors vs. outdoors). For example, a shift from 70F to 71F is unlikely to be distinctly noticed by most, but a jump from 70F to 74F might be. People often rely on broader ranges or subjective feelings (e.g., "warm" vs. "cool") rather than precise degree-by-degree distinctions.

you know what I call dictionary in this scrabble BS.

Our study employed a novel experimental paradigm, involving 26 participants, to investigate human sensitivity to environmental temperatures. The findings revealed that participants exhibited remarkable accuracy in detecting temperature changes, as shown by the JND of 0.38 C, the JND95 of 0.92 C and the CPLs of + 0.8 C and 0.91 C. This threshold appears to be smaller than those identified for specific body parts in previous studies, indicating the need for further investigation into this discrepancy. Moreover, the limited variability in participants behaviours, as indicated by the small difference between the marginal and conditional R-squared (R2m = 0.68, R2c = 0.72), suggests that the mechanism underlying thermal sensitivity could be automatic and intrinsic to every individuals body. These findings contribute to our understanding of human temperature perception and may have practical implications for energy-efficient temperature control in indoor environments.

"How hot is it?"
"36.6 degrees"
"That doesn't sound hot at all!" *goes outside and dies of heatstroke*

What about in your car? If I have the AC on in my car, 1 degree can be very noticeable, since it's blowing right on me.

Here's a study and not an AI slop response:

• America calls it customary units - not imperial units
• Congress was going to change to metric and America has its own metric standards stored away in a safe
• The internation metric standards are kept in France

Did I read correctly that they were able to detect changes on from close to 1 degree Celsius?

This is sensible enough and we can work with it.

What you're having trouble fathoming is the difference between fully integrated central air with well placed thermostats and a bunch of AC units. A central HVAC system that circulates air and has an outdoor fan blower is far more precise than a window or floor unit and the circulation creates even temperature changes that can be felt. Plus HVAC units also reduce humidity which also has a noticeable impact on how the temperature "feels" which is probably playing a part as well.

I'm more bothered by the fact that British drive on the wrong side of the road unlike America who drives on the right side of the road. How can we expect America to do the smart thing and adopt metric/celsius etc when its older brother does wrong things like driving incorrectly? Isn't there a country that uses both the metric system and drives on the right side of the road to serve as a role model for the America?

It is useful for absolutely nothing. Celsius is better suited for scientific applications,

important temperatures (0 is where water freezes, 100 is where it boils,

Nope, the original post was "if X is so good then why does the military use Y"

Celsius is fucking trash.

To be frank, I'm more surprised you don't measure caliber in burgers and cheese.

So anyway I started blasting with my quarter pounder with swiss.

BTUs means "British Thermal Units"
