To convert neutron masses to kg: multiply by 1.67492749804 × 10⁻²⁷.
mn = mp + 1.293 MeV/c². About 0.14% heavier than a proton.
For example, 1 Neutron Mass (mn) = 1.846292e-30 Short Ton (US) (ton (US)).

The neutron mass is the rest mass of a neutron, approximately 1.675 × 10⁻²⁷ kilograms, slightly heavier than a proton.
mn = mp + 1.293 MeV/c². About 0.14% heavier than a proton.
To convert neutron masses to kg: multiply by 1.67492749804 × 10⁻²⁷.
Nuclear reactor design, neutron radiography, and neutron activation analysis for material composition.
A free neutron decays into a proton, electron, and antineutrino in about 14.7 minutes. Inside a nucleus, it can be stable for billions of years.
Assuming neutrons and protons have exactly the same mass — the neutron is 0.14% heavier, which is critical for nuclear stability.
The mn > mp mass difference allows neutron beta decay (n → p + e⁻ + ν̄ₑ). Without it, atomic nuclei as we know them wouldn't exist.
The short ton (US ton) is a unit of mass equal to 2,000 pounds or approximately 907.185 kilograms.
1 short ton = 2,000 lb = 907.18474 kg = 0.90718 metric tonnes.
To convert short tons to kg: multiply by 907.185. To convert short tons to metric tonnes: multiply by 0.9072.
Coal mining output, grain production, truck payload limits, and US shipping and freight.
The US short ton (2,000 lb) is about 10% lighter than a metric tonne (2,205 lb) and about 11% lighter than a UK long ton (2,240 lb).
Assuming 'ton' means the same thing everywhere. In the US it's 2,000 lb; in the UK it's 2,240 lb; in metric it's 2,205 lb.
Remember: short ton = 2,000 lb, long ton = 2,240 lb, metric tonne = 2,205 lb. The metric tonne is between the other two.
