Everybody knows e=mc2 But what are the units? Is e in ergs, btu, horsepower, etc. Is m in gms, tons, lbs, etc? Is c in km/sec, mph, inches/day, etc?

Asked by: Donald Hobbs


All the parameters are in SI units. e.g: e (in Joules), m (Kilograms) and c (meters/second). However you can convert into your favourite units, taking into account the proper relations in between.
