## Deuteron Mass

**deuteronMass** is the mass of the deuteron, the nucleus of deuterium containing one proton and one neutron.

## Nuclear calculations

Compare it with [protonMass](https://calcul.io/constants/protonMass/index.md) and [neutronMass](https://calcul.io/constants/neutronMass/index.md). Binding energy requires mass differences and [speedOfLight](https://calcul.io/constants/speedOfLight/index.md); retain adequate precision.
