Mass vs weight on a scale

Strictly, a kilogram is mass and a pound on a bathroom scale is a unit of weight (force). Everyday converters — including this weight conversion calculator — treat them as proportional using the international avoirdupois pound of exactly 0.45359237 kg. That is the factor scales, passports, and nutrition labels use. It is not a cup-to-gram kitchen density (flour and sugar need a different tool).

What is the difference between a US ton, UK ton, and metric ton?

A metric ton (tonne) is 1,000 kg (2,204.62 lb). A US short ton is 2,000 lb (907.18 kg). A UK long ton is 2,240 lb (1,016.05 kg). Pick the matching unit in the converter if you are not converting body weight.

Common mistakes

  • Using 2.2 instead of 2.20462 for kg to lbs on large amounts — 100 kg is 220.46 lb, not 220.

  • Treating a stone as 10 lb. A stone is 14 lb.
  • Converting volume (cups) with this mass converter. Cups depend on the ingredient.
  • Rounding baby weight ounces too early. Convert the full kilogram amount, then split into lbs and oz.
