Find out how many atomic bombs worth of energy your mass contains
This calculator uses Einstein's famous equation E = mc²:
• E is energy in joules
• m is mass in kilograms
• c is the speed of light (299,792,458 m/s)
We're comparing to the Little Boy atomic bomb dropped on Hiroshima, which released about 63 TJ (63×10¹² J) of energy.
⚠️ Please note: This is a theoretical calculation. Converting mass to energy with 100% efficiency is not currently possible.
