How to use Unit Converter

  1. Pick a category such as Length or Mass.
  2. Enter a value and choose the unit you are converting from.
  3. Read the conversion into every other unit in the table.

Metric and imperial

Most of the world uses the metric system (metres, grams, litres), while the United States uses US customary units (feet, pounds, gallons) and the United Kingdom mixes metric with some imperial units. Recipes, travel, shopping online and engineering all force conversions, so having every result in one table saves time.

Handy conversions to remember

  • 1 inch = 2.54 cm.
  • 1 mile = 1.609 km.
  • 1 kg ≈ 2.205 lb.
  • 1 litre ≈ 0.264 US gallons.
  • 0 °C = 32 °F; 100 °C = 212 °F.
  • 1 acre ≈ 4,047 m²; 1 hectare = 10,000 m².

Accuracy notes

Conversion factors used here are the exact or internationally agreed values where they exist (such as the inch at 2.54 cm). Results are rounded for display to about ten significant digits. US and UK gallons, pints and cups differ, so the tool labels them. Temperature is converted with a formula rather than a simple multiplier.

Why use this unit converter tool

  • Eight categories. Length, mass, volume, area, speed, time, data and temperature.
  • All results at once. No need to pick a target unit.
  • Imperial and metric. US and UK units included.
