Everyday metric and imperial conversions
A quick, no-nonsense converter for the units real life throws at you in the UK — height in centimetres and feet, weight in kilograms and stone, temperatures in Celsius and Fahrenheit, distances in miles and kilometres, plus volume and speed. Pick a category, choose your units and type a number; the answer updates instantly.
Everything is calculated in your browser using standard conversion factors, so it works offline and nothing you type is sent anywhere. UK units are included where they differ from American ones (for example, a UK pint and UK gallon), so your conversions match what you'll actually use at home.
