The pound is an imperial unit of mass equal to exactly 0.45359237 kilograms or 16 ounces.
1 lb = 16 oz = 0.45359237 kg = 453.59237 g = 7,000 grains.
To convert pounds to kg: multiply by 0.4536. To convert kg to pounds: multiply by 2.2046.
Body weight, grocery shopping, luggage weight limits, boxing weight classes, and recipe measurements in the US.
The pound is legally defined as exactly 0.45359237 kg worldwide since 1959. 'Pound' and British '£' both trace back to the Roman libra.
Confusing pounds (mass) with pound-force (a unit of force). Also, approximately 1 kg = 2.2 lb, not 2 lb.
Quick rule: divide pounds by 2 and subtract 10% for a rough kg conversion. Example: 150 lb ÷ 2 = 75, minus 10% ≈ 68 kg.
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.
