Unit Converter
Convert between units of length, weight, temperature, area, volume, and more.
About This Tool
The Unit Converter instantly converts between units across 7 measurement categories: length, weight, temperature, area, volume, speed, and digital data.
All conversions run in your browser — no data is sent to any server. Temperature conversions use formulas (not just ratios) to correctly handle Celsius, Fahrenheit, and Kelvin.

Use Cases
Developers use the data category to convert between bytes, KB, MB, and GB. Travelers convert speed and temperature when visiting countries with different standards. Chefs rely on volume conversions between teaspoons, cups, and liters.
