Unit Converter
Select a category
Click a tab to choose from Length, Weight, Temperature, Area, Volume, Speed, Data Size, or Time. The unit dropdowns update to show only units relevant to that category.
Choose the source unit and enter a value
Select the unit you are converting from in the first dropdown and type your value. The result updates instantly without needing to press Enter.
Choose the target unit
Select the unit you want to convert to — the result appears immediately. Swap the dropdowns to reverse the conversion.
Note the Data Size distinction
For Data Size, be aware of the difference between decimal units (MB = 1,000,000 bytes) and binary units (MiB = 1,048,576 bytes). Storage manufacturers use decimal; operating systems typically report binary.
Use quick-access chips
Common conversion pairs like km↔miles or °C↔°F appear as chips for one-click setup, saving time when you repeatedly use the same conversion.
All done!
You are ready to use Unit Converter like a pro.
