About this tool
Enter a value, pick the unit you have and the unit you want, and the result updates as you type. Nine mass units are supported: kilogram, gram, milligram, metric ton, pound, ounce, stone, imperial (long) ton and US (short) ton. Conversions pass through kilograms using fixed factors, and the answer shows up to 8 decimal places. Take care with the three kinds of ton: a metric ton is 1,000 kg, a US ton is about 907 kg and an imperial ton is about 1,016 kg. Swap flips the units and Copy copies the result. Everything runs in your browser.
How to use it
- Type the weight you want to convert.
- Choose the From unit and the To unit.

Common problems
- Ton gives a different number than expected
- Pick the right ton: Metric Ton (1,000 kg), US Ton (short ton) or Imperial Ton (long ton).
- Ounces for liquids
- Ounce here is a unit of weight, not fluid volume. Use a volume converter for liquids.
- The result shows a dash
- The input is empty or not a valid number.
