Weight Converter
Switch between kilograms, pounds, ounces, stones, and tons for the things you actually weigh: yourself, a suitcase, a parcel, a bag of flour, or a truckload of cargo. Type a number, choose the unit you have, and the converter also lists the same weight in every other unit at once.
Units you can convert
- Metric: metric ton (tonne), kilogram, gram, milligram, microgram.
- US and imperial: pound, ounce, stone, US short ton, UK long ton, US hundredweight.
- Specialist: carat (for gemstones) and grain (for bullets, arrows, and medicine).
Body weight: kg, lb, and stone
Doctors, gyms, and fitness apps rarely agree on units. A reading of 70 kg is 154.32 lb, or just over 11 st, because one stone is exactly 14 pounds (11 st = 154 lb). If your UK scale shows 11 st, that is 69.85 kg.
| Body weight | Pounds | Stone |
|---|---|---|
| 60 kg | 132.28 lb | 9.45 st |
| 70 kg | 154.32 lb | 11.02 st |
| 90.72 kg | 200 lb | 14.29 st |
Luggage and shipping limits
Airlines usually publish checked-bag limits in both systems: 23 kg is 50.71 lb, and 50 lb is 22.68 kg – so the two limits are not identical. Couriers price small parcels by the ounce or gram: 500 g is 17.64 oz, and a 12 oz package is 340.19 g. For bulk freight, a US short ton is 0.907 t while a UK long ton is 1.016 t, a 12% difference that matters on a bill of lading.
Kitchen and hobby weights
Bakers moving between American and European recipes can convert ounces to grams for flour and sugar. Jewelers use the carat, which is exactly 0.2 g, and reloaders measure powder in grains (1 grain = 64.79891 mg).
If you need troy ounces for precious metals or atomic and astronomical masses, use the Mass Converter. To turn a weight into a volume, look up the density with the Density Converter.
