Unit Converter

Convert length, weight, temperature, volume, area and digital units instantly.

Unit Converter handles the conversions you actually use: length (mm, cm, m, km, inch, foot, yard, mile), weight (g, kg, oz, lb), temperature (Celsius, Fahrenheit, Kelvin), volume (mL, L, fl oz, cup, gallon), area (m², hectare, ft², acre), and digital storage (KB, MB, GB, TB and the binary equivalents). Pick a category, enter a value in any unit, and every other unit in that category updates simultaneously. There is no Convert button — the answer appears as fast as you type. Travelers use it to translate weather forecasts and grocery prices when crossing between countries that use different systems. Cooks use it to follow international recipes without a sticky-note conversion table on the counter. Engineers use it to bridge between metric specs and imperial fasteners. The conversion factors are hard-coded with the official, internationally agreed-upon ratios — nothing approximated — so the answers match what you would get from a reference textbook.
