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?
In: Mathematics
The laws of physics don’t depend on the units are used for calculations.
E=mc^2 works no matter what units are used for the measurements, so long as those units represent what’s being measured.
You could ask the same question for the imperial system. Why does the imperial system work so well for e=mc^2 despite having been invented so long before Newton and Einstein? Because e=mc^2 doesn’t depend on the units.
