Einstein Mass Energy Calculator with Mass Speed of Light

I want to calculate
Mass(m) = kg
Speed of Light in a Vacuum(c) = m/s
Energy(E) = J
 

Mass–energy equivalence is reliant on the speed of light c, the famous equation is E = mc2.

Einstein Mass Energy:

Energy: E = mc2

where, c = Speed of Light in a Vacuum, m = Mass, E = Energy.

For example, when Mass = 1 kg, speed of light = 299792458 m/s, Then Energy = 89875517873681760 J.
