About Unit Converter
Every linear unit is defined as a multiple of a base unit — the metre, kilogram, square metre, litre or metre per second — so converting is a matter of multiplying by one factor and dividing by another. The factors used here are the exact international definitions: 1 inch = 2.54 cm, 1 pound = 0.45359237 kg, 1 US gallon = 3.785411784 L, 1 mile = 1,609.344 m.
Temperature is the exception because the scales don't share a zero. Fahrenheit = Celsius × 9 ÷ 5 + 32, and Kelvin = Celsius + 273.15, so the calculator goes through Celsius for every temperature conversion.
Cup, pint and gallon sizes differ between US and UK (imperial) measures; the volume list uses US units and includes the UK gallon separately. Results are trimmed to a sensible number of significant figures for display.
Common questions
- How do I convert cm to inches?
- Divide by 2.54. There are exactly 2.54 centimetres in an inch, so 175 cm is 175 / 2.54 = 68.9 inches.
- How do I convert Celsius to Fahrenheit?
- Multiply by 9/5 and add 32. 20 C is 20 x 1.8 + 32 = 68 F. To go the other way, subtract 32 then multiply by 5/9.
