I'm not against the metric system, but there's limits.
I'm not futzing around with megapascals and newton-meters.

One megapascal is about ten times normal atmospheric pressure.
Honestly, its much more intuitive than pounds per square inch :D

KW per cm2 would be fine. I know intuitively what is an inch, a pound, a KG and a cm, but I do not know what is normal atmospheric pressure (except I know as a trivia question that it's 15ish PSI). It's like a fish doesn't know what it is to be wet.
Pressure matters when it pushes on something, so you want to know what will be the force based on the size of the something...

Fair enough.
One megapascal exerts a force of one million newtons per square meter, or about 100 tonnes per square meter on Earth at sealevel. Or 100 grams per square millimeter.

> per square meter
Also impossible to reason about because nobody uses hydraulic or pneumatic pistons that are >1 square meter of area.
KG per cm2 is human scale, but of course they loathe to use anything human scale.
The French revolutionaries who defined the metric system clearly never built anything.

I once used an air pump at a gas station, and it had BAR, and my tires specified max pressure in PSI and MPA.
CONGRATULATIONS AT SOMEHOW BEING WORSE THAN THE AMERICAN SYSTEM

Also pascals are so tiny that they need to always talk in terms of megapascals.
They might as well give your height in femtolightyears.

@cjd @npub1mts2l7rsvgpqxdc8sk39e50fpntw0p7eamq8pp3kek5h6k7qemzq83ueyt 10 bar is a MPa so it's not that bad
Fair, lol.
But they were better than Westerners today.
We redefined the SI standard reference for the volt a few years ago, in a way that makes it worse (more complicated and less accessible), simply because the original reference involves cadmium, a toxic heavy metal.
And someone might eat that, you know...
