How it works

Convert mass units used in cooking, shipping, and fitness.

When this question comes up

Weight conversion is used for luggage limits, shipping labels, recipes and fitness tracking. The most common mistake is not arithmetic but identity: a US short ton, a metric tonne and an Imperial ton are three different weights, and “oz” can mean a mass ounce or a fluid ounce.

Rules and limits

  • 1 pound = 0.45359237 kg exactly, and 1 stone = 14 pounds.
  • The metric tonne (t) is 1000 kg. The US short ton is a different unit at 907.18474 kg — check which one you need.

Worked example

1 kg = 2.2046226 lb · 10 st = 63.502932 kg

Checking the result by hand

1 pound = 0.45359237 kg exactly, and 1 stone = 14 pounds. To go from kilograms to pounds, divide by 0.45359237 — roughly multiply by 2.2046. For a quick sanity check, remember that 1 kg is a little over 2 lb, so 70 kg is a little over 154 lb.

FAQ
