Diamond grading and pricing, gemstone trade, pearl classification, and jewelry appraisal.
The Hope Diamond weighs 45.52 ct (9.1 g). The Cullinan Diamond, the largest gem-quality rough diamond ever found, was 3,106 ct (621 g).
Confusing carat (ct, mass) with karat (K, gold purity). 24K gold is pure gold; a 24-carat diamond weighs 4.8 g.
Carat = weight of a gem. Karat = purity of gold. They sound the same but measure completely different things.
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.
