About weight conversion

Strictly these are mass conversions rather than weight — mass is constant, weight is the force gravity applies to it — but everyday usage says weight, so that is the wording used here. The kilogram is the SI base unit, and since 1959 the international pound has been defined as exactly 0.45359237 kg, making conversions between metric and imperial mass exact. Note that a metric ton (1000 kg) differs from both the US short ton and the UK long ton.
