Converters
Convert between metric, imperial and other everyday or technical units, from length, mass, temperature and volume to energy, power, pressure, angle, fuel economy, density and frequency, or use the general Unit Converter for any of them.
Convert length, mass, temperature (including oven Gas Marks), area, volume, speed, data storage, energy, power, pressure, angle, fuel economy, density, frequency or currency between the units each converter supports, or use the Unit Converter for a quick conversion in any of these categories. US customary and Imperial units are always kept clearly distinct where both exist.
Converting a recipe's Imperial pints to millilitres, checking a file size in KiB versus kB, comparing mpg with litres per 100 km, or converting a price into another currency.
Conventions and limitations
A US gallon and an Imperial gallon are different sizes, and so are US and Imperial miles per gallon, the decimal (kB) and binary (KiB) data-storage units, and mechanical and metric horsepower. Numerila never blurs these distinctions together. A plain number in a result is exact; a result starting with ≈ is rounded to 10 significant figures.
