EDIT: or humidity, which is also going to be a major factor in how much you can stand.
The official Fahrenheit scale is something that only USA can love.
The Aspden scale has its zero at water-freezing and 100 at this-will-kill-you-if-you-can't-sweat. 50A is "nice". It's really intuitive and perfect for weather reports. For science, use Kelvin of course.
It's approx the temp that sea water freezes at. That's not useless.
212-32= 180 degrees between fresh water freezing and boiling.
The metric system has its merits, but US units aren't as arbitrary or pointless as people think. It may not be made for decimalization, but it does feature units that are easily divisible by even numbers and 1/8ths.
It's a balance between useful approx characteristic points and convenient divisors.
And based on how many people struggle with knowing where to put the decimal (or use the correct prefix) in metric, I'd argue decimalization isn't the great "simplification" it's made out to be.
And the fact that people think the decimalization of time would be crazy is proof that it's more about familiarization than simplicity.
what’s not to like about this human-perspective?
That then would be the foot in the door for eventual full metric conversion!
(This distinction is important in rocketry. At a given exhaust temperature, the lighter substance will be moving faster, resulting in greater efficiencies.)
So basically:
(Sum of the speed * mass of (from atom[1] to atom[total number])) divided by the total number of atoms?
(and without quite knowing what temperature is, but that's besides the point)
