Unit Converters

Length, weight, volume and temperature converters: cm to inches, kg to lbs, Celsius to Fahrenheit and more. 84 tools, all running in your browser.

Each converter uses exact or internationally agreed conversion factors, such as 1 inch = 25.4 mm and 1 pound = 453.59237 g. Results are rounded for display only.

Where countries use different versions of a unit, such as the US and UK gallon or fluid ounce, the page says which one it uses.
