Common mistakes
- Precious metals use the troy ounce (31.1034768 g), about 10% heavier than the avoirdupois ounce (28.349523125 g) used for food and parcels.
- "Ton" is ambiguous: the metric tonne used here is 1,000 kg, the US short ton 907.18474 kg and the UK long ton 1,016.0469088 kg.
- Kilograms and pounds measure mass. Pound-force (lbf) and newtons measure force — they are not interchangeable with kg.
