Why do the units in e=mc^2 all work out for such a clean equation?

1.13K viewsMathematicsOther

I might just be stupid because math is not my strong suit, but it seems like the fact that metric units are able to convert between mass and energy so cleanly is astounding. Especially since the metric system was invented so long before relativity, meaning these units were obviously not designed with this in mind.

What’s am I missing here? Is it possible to write an equivalent equation for imperial units?

Much of physics is understanding ratios. Some of this is equal to several of that. Now toss in some modifiers and constants, and you get a relationship you can show as an equation.

Squeeze air and it gets hot. On the way, the volume went down as the temperature went up. Keep the volume and increase the pressure: air gets hot. Keep track of the moving parts, and the stationary parts, and you’ll wind up with PV=nRT

Lather, rinse, repeat for the rest of the universe, and you get things like the Gravitational Constant, Stefan-Boltzman’s Law, Ohm’s Law, and how to properly cook a cheeseburger.

That last one is still undergoing peer review at my holiday party this 4th of July. I’ll let you know how it turns out.
