How to Convert Atomic Mass Unit to Long Ton (UK)
To convert u to kg: multiply by 1.6605390666 × 10⁻²⁷. To convert u to MeV/c²: multiply by 931.494.
1 u = 1.6605390666 × 10⁻²⁷ kg = 1/Nₐ grams ≈ 931.494 MeV/c².
For example, 1 Atomic Mass Unit (u) = 1.634313e-30 Long Ton (UK) (ton (UK)).

About Atomic Mass Unit (u)
Definition
The atomic mass unit (unified) is defined as 1/12 the mass of a carbon-12 atom, approximately 1.661 × 10⁻²⁷ kilograms.
Mathematical Relationship
1 u = 1.6605390666 × 10⁻²⁷ kg = 1/Nₐ grams ≈ 931.494 MeV/c².
Conversion Formula
To convert u to kg: multiply by 1.6605390666 × 10⁻²⁷. To convert u to MeV/c²: multiply by 931.494.
Practical Applications
Molecular weight calculations, mass spectrometry data interpretation, and chemical stoichiometry.
Interesting Facts
A proton has a mass of ~1.007 u, a neutron ~1.009 u. The discrepancy from 1.000 reflects nuclear binding energy.
Common Mistakes
Confusing 'amu' (the old, obsolete term) with 'u' (the unified standard). Also, forgetting that 1 u ≠ 1 gram.
Educational Tips
Think of u as 'approximately the mass of one proton or neutron.' Carbon-12 = 12 u exactly (by definition).
About Long Ton (UK) (ton (UK))
Definition
The long ton (imperial ton) is a unit of mass equal to 2,240 pounds or approximately 1,016 kilograms.
Mathematical Relationship
1 long ton = 2,240 lb = 1,016.047 kg = 1.016 metric tonnes = 1.12 short tons.
Conversion Formula
To convert long tons to kg: multiply by 1,016.047. To convert long tons to short tons: multiply by 1.12.
Practical Applications
Ship displacement tonnage (historical, some naval vessels still use it), and some UK agricultural contexts.
Interesting Facts
Naval ship displacement is traditionally given in long tons. HMS Titanic displaced about 52,310 long tons.
Common Mistakes
Assuming a 'ton' is a 'ton' — the long ton is 12% heavier than a short ton and 1.6% heavier than a metric tonne.
Educational Tips
Easy memory: Long ton = British = 2,240 lb (long = larger). Short ton = US = 2,000 lb (short = smaller).
