What is a unit converter?
A unit converter translates a measurement from one unit to another — for example 5 miles to kilometers, 2.5 kg to pounds, or 300 K to Celsius. Manual conversions are error-prone: every unit family has its own conversion factors, and mixing up meters with feet or liters with gallons can throw off a recipe, a shipping label, or a calculation at work.
This unit converter covers the four unit families people convert most: length, weight, temperature, and volume. It runs entirely in your browser — pick a category, enter a value, choose the source and target units, and the result appears instantly. There is no signup, no download, and no limit on how many conversions you make.

- Enter the value and choose the unit you are converting from and the unit you want the result in.
