The source character set is implementation defined.

You could even choose the name this.

I didn’t know that the feds accredited universities. When I was in school, the one that mattered for engineering was ABET or somesuch.

I think a lot of people understand the concept of light-seconds, which can measure distance in seconds.

Allow me to introduce the gravity-second. 1 gravity-second of mass-energy is enough mass-energy to have a Schwarzchild radius of 2 light-seconds.

Set G = 1 and c =1. Then equations like r = 2m make dimensional sense.
