To convert deuteron masses to kg: multiply by 3.3435837724 × 10⁻²⁷.
md < mp + mn by 2.224 MeV/c² (the binding energy). This 'mass defect' represents nuclear binding energy.
For example, 1 Deuteron Mass (md) = 1.536267e-19 Planck Mass (mₚ).

The deuteron mass is the mass of a deuterium nucleus (one proton + one neutron), approximately 3.344 × 10⁻²⁷ kilograms.
md < mp + mn by 2.224 MeV/c² (the binding energy). This 'mass defect' represents nuclear binding energy.
To convert deuteron masses to kg: multiply by 3.3435837724 × 10⁻²⁷.
Fusion energy research (deuterium-tritium and deuterium-deuterium reactions), NMR/MRI, and neutron production targets.
The deuteron's binding energy (2.224 MeV) is quite small, making it the most weakly bound stable nucleus.
Assuming md = mp + mn exactly — the mass defect (binding energy) makes the deuteron slightly lighter than the sum.
The deuteron is the simplest nucleus with more than one nucleon. Its binding energy (2.224 MeV) is E=mc² in action.
The Planck mass is the fundamental natural unit of mass, approximately 2.176 × 10⁻⁸ kg (about 21.76 micrograms).
mₚ = √(ℏc/G) ≈ 2.176 × 10⁻⁸ kg ≈ 21.76 µg ≈ 1.31 × 10¹⁹ proton masses.
To convert Planck masses to kg: multiply by 2.176434 × 10⁻⁸.
No direct practical applications — a Planck mass is roughly the mass of a flea egg, but its significance is theoretical.
Unusually, the Planck mass is macroscopic (~22 µg) — about the mass of a flea egg, a grain of sand, or a small dust mite.
Expecting Planck mass to be extremely small like other Planck units — it's actually macroscopic (~22 µg).
Other Planck units are absurdly small or large, but the Planck mass is surprisingly human-scale: about 20 micrograms.
