Unit Converter and Rates

Use it for seasonal angles — travel season, tax season, a rate that just moved.

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.

BUILT FOR ONE THUMB • A large, uncluttered keypad • Swipe through units without opening a menu • Switch direction with one tap • Tap the result to copy it

IN YOUR LANGUAGE English, Arabic, German, Spanish, French, Hebrew, Indonesian, Italian, Japanese, Portuguese (Brazil), Russian, Turkish and Simplified Chinese — with full right-to-left layout in Arabic and Hebrew, not just translated text.

FREE TO USE Unit Converter is free and supported by ads. An optional subscription removes them.
