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) = 2.013553213 Dalton (Da).

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 dalton is a unit of mass equal to one unified atomic mass unit (1/12 of a carbon-12 atom), approximately 1.661 × 10⁻²⁷ kg.
1 Da = 1 u = 1.6605390666 × 10⁻²⁷ kg. Proteins range from ~5 kDa to >1,000 kDa.
To convert Da to kg: multiply by 1.6605390666 × 10⁻²⁷. 1 kDa = 1,000 Da.
Protein molecular weights (hemoglobin ≈ 64.5 kDa), DNA fragment sizing, and antibody characterization.
Titin, the largest known protein, has a molecular weight of about 3,800 kDa (3.8 MDa). The average protein is ~40–50 kDa.
The dalton and u are identical — they're just preferred in different fields (Da in biology, u in chemistry/physics).
If a paper says a protein is '50 kDa,' that's 50,000 atomic mass units — about 50,000 hydrogen atoms' worth of mass.
