Here are the variables for the equation
E = energy
c = the speed of light, 299 792 458 m/s
m = the mass in kilograms.
Output﻿﻿E (1)
:4.49377589e+17J​

m =Ec2m\ = \frac{E}{c^2}m =c2E​
ExplanationEinstein's famous equation, E = mc^2, relates mass and energy - read more about Newton's 3 Laws of Motion here. It states that mass can be converted into energy and vice versa, and the amount of energy released is proportional to the amount of mass converted.
Einstein's idea of energy equivalency is relevant to many other scientific disciplines, such as chemical reactions, nuclear reactions and other energy transformations.
