Quick conversions

What this tool converts

13 categories in one place — length, weight, temperature, time, speed, area, volume, data, energy, pressure, angle, power and frequency. Each category covers 6–12 of the most-used units. All conversions happen in your browser, with double-precision floating point — the same precision used by Google and physics software.

Notes on precision

  • Results are shown with up to 10 significant digits. Values too large or too small switch to scientific notation automatically.
  • "Month" is fixed at 30 days and "Year" at 365 days. For calendar-accurate month/year calculations, use a dedicated date calculator.
  • "Mach" uses the speed of sound at sea level (343 m/s). It varies with altitude and temperature.
  • Metric data units (KB, MB, GB) are powers of 1000 — the official SI definition. Binary units (KiB, MiB, GiB) are powers of 1024 — what operating systems use internally.
  • US and UK gallons differ. We include both — pick the one matching your use case.

Useful reference points

  • Water freezes at 0 °C = 32 °F = 273.15 K.
  • Water boils at 100 °C = 212 °F = 373.15 K (at sea level).
  • 1 mile = 1.609 km · 1 foot = 0.305 m · 1 inch = 2.54 cm.
  • 1 kg = 2.205 lb · 1 pound = 453.59 g.
  • 1 litre = 0.264 US gallons · 1 US gallon = 3.785 litres.
  • 1 hectare = 2.471 acres · 1 acre = 4,047 m².

Tips

  • Click any row in the "Quick conversions" table to lock that unit as the target.
  • Use the swap button (⇆) to flip the source and target units without re-typing.
  • Scientific notation is supported in the input box — type 1e6 for one million.
