Worth knowing
The pound is defined as exactly 0.45359237 kilograms, so one kilogram is 2.2046226 pounds. The familiar shortcut of 2.2 is close, but it drifts by about a fifth of a pound at 100 kilograms — enough to fail an airline baggage check.
The mistake to avoid
Doubling the kilogram figure and adding ten per cent is a popular mental shortcut, and it is a reasonable approximation, but it drifts noticeably above 100 kg. For anything going on an official form, use the exact factor of 2.2046226.
