How it works

This page is the unit converter with kilograms to pounds chosen. Conversions use the js-quantities library, which keeps the exact definitions of the units (1 pound is 0.45359237 kg), and the results are shown to eight significant digits.

Where the number comes from

Since the international yard and pound agreement of 1959, the pound is defined as exactly 0.45359237 kilograms, and an ounce is exactly one sixteenth of a pound. Dividing 1 by 0.45359237 gives the 2.2046226 that appears on this page. Nothing was measured to get it, so every digit is a definition and the conversion has no rounding error of its own.

Weights you might look up

kg	lb	lb	kg
50	110.23	100	45.36
60	132.28	150	68.04
70	154.32	175	79.38
80	176.37	200	90.72
90	198.42	14 (one stone)	6.35
100	220.46	50	22.68

Bags and parcels follow the same arithmetic: 20 kg is 44.09 lb, 23 kg is 50.71 lb and 32 kg is 70.55 lb. A limit written as 50 lb is therefore a little under 23 kg, and a bag at 23 kg is a little over 50 lb.

Mistakes to avoid

Do not round 2.2046 to 2 in your head for anything that matters: 70 kg would come out as 140 lb, a full 14 lb short. The shortcut 2.2 is close enough for a quick idea, and the error grows with the weight. Also check which unit a recipe or a label means by oz: this page uses the ounce of weight (28.35 g), which is not the fluid ounce used for liquids.
