To convert tonnes to kg: multiply by 1,000. To convert tonnes to short tons: multiply by 1.10231.
1 t = 1,000 kg = 10⁶ g = 2,204.62 lb = 1.10231 short tons = 0.98421 long tons.
For example, 1 Metric Ton (t) = 6.022141e+29 Atomic Mass Unit (u).

The metric ton (tonne) is a unit of mass equal to 1,000 kilograms or one megagram.
1 t = 1,000 kg = 10⁶ g = 2,204.62 lb = 1.10231 short tons = 0.98421 long tons.
To convert tonnes to kg: multiply by 1,000. To convert tonnes to short tons: multiply by 1.10231.
Cargo shipping, vehicle weight ratings, construction material ordering, and agricultural harvests.
The three 'tons' often cause confusion: metric tonne (1,000 kg), short ton (907 kg, US), and long ton (1,016 kg, UK).
Confusing metric tonnes with short tons (US) or long tons (UK). A metric tonne is 10% heavier than a US short ton.
1 tonne = ~2,200 lb. Quick check: multiply tonnes by 2.2 to get approximate thousands of pounds.
The atomic mass unit (unified) is defined as 1/12 the mass of a carbon-12 atom, approximately 1.661 × 10⁻²⁷ kilograms.
1 u = 1.6605390666 × 10⁻²⁷ kg = 1/Nₐ grams ≈ 931.494 MeV/c².
To convert u to kg: multiply by 1.6605390666 × 10⁻²⁷. To convert u to MeV/c²: multiply by 931.494.
Molecular weight calculations, mass spectrometry data interpretation, and chemical stoichiometry.
A proton has a mass of ~1.007 u, a neutron ~1.009 u. The discrepancy from 1.000 reflects nuclear binding energy.
Confusing 'amu' (the old, obsolete term) with 'u' (the unified standard). Also, forgetting that 1 u ≠ 1 gram.
Think of u as 'approximately the mass of one proton or neutron.' Carbon-12 = 12 u exactly (by definition).
