About converting kilograms to pounds

Mass and weight are different quantities, and the kilogram-to-pound conversion quietly straddles both. Strictly, a kilogram measures mass and a pound-force measures weight, but the pound used on scales and shipping labels is the avoirdupois pound of mass, defined since 1959 as exactly 0.45359237 kilograms. On Earth the distinction rarely matters; the everyday conversion is exact and unambiguous. Where it becomes confusing is that several different pounds have existed and one still circulates. The troy pound, used for precious metals, is about 373 grams rather than 454, which is why a pound of gold and a pound of feathers genuinely are different weights when the gold is quoted in troy. Precious metals are normally priced per troy ounce, at 31.1 grams against the ordinary ounce of 28.35. The other practical trap is the stone, used for body weight in Britain and Ireland and essentially nowhere else. Fourteen pounds to the stone is not obvious to anyone outside that convention, and medical figures given in stone convert to pounds and kilograms in ways that surprise people used to a single unit.

Frequently asked questions

How many pounds is 70 kg?
70 kilograms is 154.32 pounds, which is 11 stone 0.3 pounds. Rounding to 154 pounds or 11 stone is normal in everyday use, since bathroom scales are rarely accurate to a tenth of a pound anyway.
What is a stone?
Fourteen pounds, used almost exclusively in Britain and Ireland for body weight. It is not used in the United States, where the same weight is given in pounds alone — which is why an American and a Briton describe the same person very differently.
Is the conversion exact?
Yes. The international pound has been defined as exactly 0.45359237 kilograms since 1959. Anything you see beyond a few decimals is display rounding rather than uncertainty in the relationship.
Does this work for airline baggage limits?
The arithmetic does, but check what the limit refers to. Most airlines weigh the bag including its own weight, and a hard case can be four or five kilograms before you pack anything. Convert the limit, then subtract the empty case.
