The Unit Converter changes a value from one unit to another across 11 kinds of measurement: length, weight, temperature, volume, area, speed, time, digital storage, energy, pressure and fuel economy. It covers metric units (centimetres, kilograms, litres), US and UK imperial units (inches, pounds, gallons) and everyday ones such as cups, stones, acres and kilowatt-hours.
Conversions use the official definitions — 1 inch is exactly 2.54 cm, 1 pound exactly 0.45359237 kg, 1 US gallon exactly 3.785411784 litres — and the page shows the factor, the formula, the value in every other unit and a chart of common values, so you can check or reuse the numbers.
When to use it
- Converting height and weight between metric and imperial (cm ↔ feet and inches, kg ↔ lbs).

- Reading weather and oven temperatures in Celsius or Fahrenheit.
- Property sizes in square feet, square metres, acres and hectares.
- File sizes (MB ↔ GB), fuel economy (mpg ↔ L/100 km) and tyre pressure (psi ↔ bar).
