Frequently asked questions

Which unit categories are supported?

Eight: length, weight, temperature, area, volume, speed, data and time — covering the conversions people need day to day.

How do I convert Celsius to Fahrenheit?

Choose the temperature category, set Celsius to Fahrenheit, and type the value — e.g. 25°C converts to 77°F. Temperature uses the proper offset formula, not a simple ratio.

Does it convert both ways?

Yes — pick any pair of units in either direction within a category: miles to km, km to miles, kg to lb, lb to kg, and so on.

Does it work offline?

Once the page has loaded, yes — conversion is pure local math, no lookup calls. Useful when you're converting units precisely because connectivity is limited.

Is Unit Converter free to use?

Yes. Unit Converter is completely free on GenRise, with no limits, watermarks, or hidden paywalls.

Yes. Since Unit Converter processes everything in your browser, your files never leave your device. There is no server-side storage, no tracking of file contents, and no data collection.
