Where the number comes from

A pound is exactly 0.45359237 kilograms. That is a definition from the 1959 agreement that also fixed the inch, so there is no measurement error in the factor. Going from kilograms to pounds means dividing by it, which is why the answer is 2.204623 and carries on.

In your head: double it, then add ten per cent. Seventy kilograms doubles to 140, plus 14 makes 154, and the exact answer is 154.32. At body weights that trick lands within a fifth of a pound.

One caution. This is the international avoirdupois pound, the one on every bathroom scale. Precious metals are still sold in troy pounds and troy ounces, which are different weights, so a gold figure converted here will be wrong.

Frequently asked questions

How many pounds are in a kilogram?
About 2.204623. The clean number runs the other way: a pound is exactly 0.45359237 kilograms. That figure is a definition, agreed in 1959, not a measurement.
Is there a rule I can do in my head?
Double it and add ten per cent. Seventy kilograms doubles to 140, plus 14 is 154, and the exact answer is 154.32. That is accurate to a fifth of a pound at body weights.
Can I get stone and pounds?
Yes. Set the To field to Stone and the answer comes with a stone and pounds line under it. A stone is fourteen pounds exactly.
Is a pound the same everywhere?
The one here is, and it is the one nearly everybody means. It is the international avoirdupois pound. Troy pounds are still used for precious metals and are a different weight, so do not use this for those.
Should this say mass or weight?
Strictly it converts mass, and the kilogram and pound are both units of mass. Scales say weight, so that is the word most people search for. On Earth the distinction does not change the number.
Is there a limit on conversions?

Does this work without an internet connection?
