Convert anything, in two taps. Unit Converter turns any measurement into any other — 138 units across 14 categories — and converts 162 world currencies at live rates. Pick a category, type a number, read the answer. No sign-up, no account, nothing to configure. EVERY MEASUREMENT YOU ACTUALLY USE • Length, Weight, Volume, Area, Speed, Temperature • Pressure, Power, Density, Time, Data • Fuel Mileage, including the ones most converters get wrong: km/L, L/100 km, MPG in both US and UK gallons • Gas Flow and Liquid Flow LIVE CURRENCY RATES 162 currencies, refreshed from a live feed, with the update time shown right under the title so you always know how fresh your rate is. Dollars to euros, pounds to yen, dirhams to rupees — cross-rates go through the base currency, so any pair works. WORKS WITHOUT A CONNECTION Every unit conversion runs on your device. On a plane, in a basement, or abroad with data switched off, length, weight, volume and the rest keep working. Currency rates need a connection to refresh; the last rates fetched stay available until they do.
