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...

What is "standard gravity" even means? Elon Musk going to transport most of our air, water and hydrogen fuel to the Moon and to Mars, and this is Earthling Genocide and Musk is a Galactic Criminal. We are going to hold a March on SpaceX, and demand that the corporation is forced to move to Pluto! Protect the SI, make your voice heard across the Solar System! /S

> In reality, a pound operating at a distance of one foot does not exert as much force in Fairbanks as it does in Los Angeles.

A foot-pound of work is the same because it's based on pound-force which is standardized, not a pound-mass.

It's exactly the same as a newton, except if a newton was defined as "force of 1KG mass at standard gravity". The problem is that 1 newton is nowhere near the force of 1KG so it's impossible to intuitively reason about it.
> 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.
