Weight Converter

Everything converts through the ounce: value x (ounces per the unit you have) / (ounces per the unit you want). The anchor is exact: 1 pound is 0.45359237 kilograms. A pound is 16 ounces, a stone 14 pounds, and a US ton 2,000 pounds against a metric ton of 1,000 kilograms.

How many pounds are in a kilogram?

About 2.20462 pounds. For mental arithmetic, double it and add ten percent: 70 kg becomes 140 plus 14, or 154 pounds, against a true 154.3.

What is the difference between a US ton and a metric ton?

A US or short ton is 2,000 pounds, about 907 kg. A metric ton is 1,000 kg, about 2,205 pounds, so it is roughly ten percent heavier. There is also a British long ton of 2,240 pounds, which this leaves out because almost nobody uses it now.

Why do the UK and Ireland weigh people in stones?

Custom, mostly. A stone is 14 pounds, so 12 stone is 168 pounds or 76 kg. It survives for body weight in those countries while everything else there went metric decades ago.
