Binding Energy Calculator
Compute rest energy E = mc² of a mass (mass-energy equivalence).
Input Data
Mass Kg
kg
Results
E = mc².
0J
In mega-electronvolts.
931.494065MeV
At a glance:E = m·c² (rest energy). Complements mass-energy-equivalence and nuclear-binding-energy.
Formula
E = m·c².
$$E = m c^2, \quad c = 2.9979 \times 10^8\,\text{m/s}, \quad 1\,\text{u} = 931.5\,\text{MeV}/c^2$$How to Use
- Enter a mass.
- The tool returns energy in J and MeV.
Case Studies
m=1 kg
E ≈ 9e16 J.
