Isotope Mass ↔ Energy calculator

Convert atomic mass (u) to energy via E = mc².

Category: Unit Converters

Formula: E = m · c²

Inputs

InputParameterUnitDefault
Massmu1

Result with the default inputs

  • Energy: 1.4924e-10 J
  • Energy: 931.4941 MeV
  • Mass: 1.6605e-27 kg

Open it with your own values: put each input in the address as a parameter, for example /calculators/isotope-mass-energy?m=1. A unit other than the listed one goes in <parameter>_unit.
