Convert length, weight and temperature instantly.
What is a unit converter?
A unit converter changes a measurement from one unit to another — for example, kilometres to metres, kilograms to pounds, or Celsius to Fahrenheit. It covers length, weight and temperature, so you can convert measurements for school, cooking, travel and work without looking up conversion factors.
How to use the unit converter
Choose the category (Length, Weight or Temperature), enter the value, pick the unit to convert from and the unit to convert to, then click Convert. The answer appears straight away.
Formula
Converted value = value × (from-unit in base units) ÷ (to-unit in base units). For length, metres are the base unit: 1 km = 1000 m, 1 ft = 0.3048 m and 1 mi = 1609.344 m.
Example
1 km = 1000 m, because 1 × 1000 ÷ 1 = 1000. Try it above: set From to km, To to m, Value to 1, and click Convert.
