Units explained
Deuteron Mass
The deuteron mass is about 3.344E-27 kg.
The mass of the deuteron, the nucleus of deuterium (one proton and one neutron).
Nuclear physics and fusion-energy research.
Established with the discovery of deuterium by Harold Urey in 1931.
Neutron Mass
The neutron rest mass is about 1.6749E-27 kg, slightly more than the proton.
The mass of the neutron, the neutral nucleon.
Nuclear physics and reactor science.
Determined after James Chadwick discovered the neutron in 1932.
Deuteron Mass to Neutron Mass conversion formula
Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.
The relationship between deuteron mass and neutron mass:

Step-by-step: convert deuteron mass to neutron mass
- Write down the value in deuteron mass (md).
- Multiply that value by the factor 1.9962558404.
- The product is the equivalent value in neutron mass (mn).
- To reverse, multiply the neutron mass value by 0.5009377955.
Worked examples
Example 1 — Convert 1 md to mn:
1 × 1.9962558404 = 1.9962558404 mn
Example 2 — Convert 100 md to mn:
100 × 1.9962558404 = 199.6255840398 mn
Real-world example — Wavelengths across the spectrum
Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 deuteron mass can be re-expressed in neutron mass for direct comparison with another instrument's calibration data sheet.
800 md × 1.9962558404 = 1597.0046723186 mn
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 deuteron mass) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 md × 1.9962558404 = 3.9925116808 mn
