About this tool
The pound is defined as exactly 0.45359237 kg, so 1 kg ≈ 2.20462 lb. One avoirdupois ounce is 1/16 lb (28.3495 g), but precious metals use the heavier troy ounce (31.1035 g). “Ton” is ambiguous: a US short ton is 2,000 lb, a UK long ton is 2,240 lb, and a metric tonne is 1,000 kg (2,204.6 lb).
