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) = 3.343584e-9 Femtogram (fg).

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 femtogram is a unit of mass equal to 10⁻¹⁵ grams or 10⁻¹⁸ kilograms — one quadrillionth of a gram.
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg = 1,000 ag.
To convert fg to kg: multiply by 10⁻¹⁸. To convert fg to pg: divide by 1,000.
Expressing the mass of individual bacterial cells (~100 fg for E. coli) and subcellular components.
A single E. coli bacterium has a mass of about 600–700 fg. A single mitochondrion is roughly 1 fg.
Mixing up fg (femtogram) with fm (femtometer) — one is mass, the other is length.
A bacterium weighs ~500 fg — this gives you a tangible anchor for the femtogram scale.
