Formula and example

How it is calculated

Conversion uses a common base unit; MPG and km/l use a reciprocal relationship.

Worked example

5 l/100 km = 20 km/l.

Things to check

  • A US gallon is 3.785411784 litres; an imperial gallon is 4.54609 litres. Lower l/100 km means better economy, while higher km/l or MPG means better economy. Reciprocal conversion requires a positive value.
  • Rounding is applied only to displayed results. Very small or very large values may appear in scientific notation.
