Unit Converter

What is Unit Converter

The Unit Converter converts between the main units of measurement — length, weight, temperature, volume, speed, area, data and time — with an instant result as you type.

All calculations happen in the browser, with no connection and nothing sent: you can use it offline.

How it works

1. Choose the category (length, weight, temperature…).
2. Select the source unit and the target unit.
3. Type a value: the conversion appears instantly.
4. Switch units freely to compare results.
