Mass-Energy Equivalence Converter

 

This handy tool allows you to explore the profound relationship between mass and energy as described by Einstein's famous equation, E = mc². With this converter, you can easily convert mass into energy and vice versa, gaining a deeper understanding of the incredible interplay between these fundamental concepts. Simply input the mass of matter in kilograms to calculate the corresponding energy in joules, or enter the energy in joules to determine its equivalent mass.

KNOW THAT the speed of light is assumed to be approximately 2.998 × 10^8 m/s, and the result is displayed in joules.
