Weight Converter

About the Weight Converter

The Weight Converter translates measurements between every common unit — kilograms, grams, pounds, ounces, stones, tons (metric, US short, UK long), milligrams, micrograms, and more. Travellers crossing between metric and imperial countries, cooks following international recipes, parents tracking baby weight, fitness enthusiasts logging gym progress, and scientists working with lab samples all use weight conversion daily.

Units supported

Metric: milligrams (mg), grams (g), kilograms (kg), metric tons (t). Imperial / US: ounces (oz), pounds (lb), stones (st), short tons (US), long tons (UK). Specialised: troy ounces (precious metals), carats (gemstones), grains (ammunition, medication), micrograms (mcg, used in vitamin doses). Every conversion uses the internationally agreed values (1 lb = 0.45359237 kg exactly).

All conversions run in your browser using simple multiplication. Nothing is sent to our servers. The tool works offline once loaded — useful when checking weights at a market with no signal.
