Unit Converter: convert any measurement, currency or size in one tap.
IN SHORT
A fast, offline unit converter that turns any measurement, currency or clothing size into the answer you need — with live exchange rates and a built-in calculator. If you can use a calculator, you can use this.
WHO IT'S FOR
Cooks, contractors, DIY-ers, students, travelers and anyone who needs a quick, precise conversion. Also handy for engineers, nurses and online shoppers comparing international sizes.
WHAT YOU GET
• 18+ categories in one place — weight, length, temperature, volume, speed, area, time, data, energy and more.
• Live currency conversion — real-time exchange rates, updated automatically.
• A real calculator built in — type an expression and convert the result instantly.
• Works offline — every unit (except live rates) converts with no connection.
HOW IT WORKS
1) Pick a category from the icon grid.
2) Tap the two units you want and type a value — or a full calculation.
3) Read the precise result instantly, to the number of decimals you choose.
