Unit Converter
Convert between common units of length, weight, volume, temperature and speed.
About the Unit Converter
Unit Converter handles everyday unit swaps — kilometres to miles, Celsius to Fahrenheit, litres to gallons, kg to lb — with double-sided inputs so you can type in either side.
How to use
- Pick the category (length, weight, temperature, volume, speed).
- Type a value in either input; the other updates instantly.
- Swap categories without losing your number.
Benefits & key features
- Five most-used categories in one minimal interface.
- Bidirectional inputs — no 'from / to' guesswork.
- No currency conversions (rates change hourly, so we don't pretend).
- Works without an internet connection after first load.
Pro tip
Temperature conversions use the exact formulas (°F = °C × 9/5 + 32) rather than rounded lookup tables.
