Weight and Mass Converter

Kilos on the scale, pounds on the label

A European airline caps checked bags at 23 kg, a recipe from a British site asks for 250 grams of flour, a dumbbell set from abroad lists its weight in kilos. Jood's weight converter works between six units: kilogram, gram, milligram, tonne, pound and ounce.

How to use it

1. Enter the value; a dot or a comma both work as the decimal mark.
2. Choose the unit you are converting from and the one you want.
3. Click "Start Now" to see the result with the unit name.

Examples worked out with the tool

• A 23 kg suitcase weighs 50.7063 lb, and a 50 lb limit is 22.6796 kg.
• 8 oz of butter is 226.7962 g, and 500 g is 17.637 oz.
• One pound is 453.5924 g, and one tonne is 2,204.6226 lb.

The tool uses the international definition: a pound is exactly 0.45359237 kg. The tonne is the metric tonne of 1,000 kg, not the US short ton of 2,000 lb, which is about 907 kg.

Careful: gold is weighed in a different ounce

The ounce in this tool is the ordinary avoirdupois ounce used for cooking and parcels: 28.3495 g. Gold and silver prices are quoted per troy ounce, which is about 31.1035 g. If you work out the price of a gram of gold from the world price, divide by 31.1035 rather than using this tool's ounce, or you will be off by roughly 10%.

When you will need it

• Travel: airlines outside the US set baggage limits in kilograms.
• Cooking: European and Australian recipes measure in grams.
• Fitness: gym plates and dumbbells are labeled in kilos in many countries.
• Shipping: international couriers may quote by the kilogram.

For liquid amounts in a recipe, such as cups and fluid ounces, use the volume converter. The calculation runs on Jood's server in an instant and nothing is stored.
