Common mistakes
- ✕Confusing pounds (lb) with pound-force or with the British stone (1 st = 14 lb).
- ✕Rounding too aggressively — 1 lb = 0.4536 kg, not 0.45 kg; the error compounds on large weights.
- ✕Using US "cups" for solid weight — cups are a volume unit, not a mass unit.
- ✕Short ton, long ton and tonne are three different units. A US short ton is 2000 lb = 907.18474 kg. A UK long ton is 2240 lb = 1016.0469088 kg. A metric tonne is 1000 kg. Freight and commodity figures are wrong by up to 12% if these are mixed up.
