A short history of weight units

Weight (technically mass in everyday usage) was historically measured against grain or stone references, with each region defining its own pound. The kilogram was originally fixed in 1799 as the mass of one litre of water at 4°C, then redefined in 2019 in terms of the Planck constant. The avoirdupois pound used in the US and UK is exactly 0.45359237 kg by international agreement.

Common mistakes when converting weight

Confusing pounds-mass with pounds-force

Everyday "pound" is mass; in engineering, lbf is a force unit. They share a name but measure different things.

Using short ton instead of metric ton

A short ton is 907.185 kg, a long ton is 1016.047 kg, and a metric ton (tonne) is exactly 1000 kg.

Carat vs karat

Carat is a mass unit for gemstones (200 mg). Karat is a purity measure for gold. Same sound, different meaning.
