How to use this tool

  • Enter a value using a decimal point or scientific notation.
  • Choose the input and output units. For temperature, choose absolute values or differences.
  • Select Convert units, review the result and download the text if useful. Reset restores defaults.

Examples

5 litres per 100 kilometres = 20 kilometres per litre.

Limitations

  • Uses floating-point arithmetic with output rounded to 12 significant digits. Maximum input magnitude is 1e100. Nonzero values or results outside the floating-point range are rejected. No network request is needed for calculation.
  • Values must be positive. Consumption and economy vary inversely; U.S. and imperial MPG are different.
