Megaelectron volts to atomic mass units
Type a value in MeV to get it in u instantly.
0.001074u
That's 1.96× as much as an electron, while a proton is 938× more. That energy would run about 1.272×10⁻²³ homes for a year.
Convert the other way: u to MeV
What it means
How much energy is that?
This is the full rest energy. No process releases all of it: fission converts about 0.1% of the fuel’s mass, and chemical burning around a billionth.
The math
How to convert MeV to u
To convert megaelectron volts to atomic mass units, multiply by 0.00107354.
Example: 1 MeV × 0.00107354 = 0.00107354 u.
In the other direction, 1 u = 931.494 MeV.
