How to convert Fuel Economy

Fuel economy uses inverse relationships: a lower L/100 km value represents better fuel economy, while a higher MPG or km/L value represents better fuel economy.

Units included

Miles per US Gallon (mpg (US)), Miles per Imperial Gallon (mpg (Imp)), Kilometers per Liter (km/L), Liters per 100 km (L/100 km).

Conversions are mathematical reference conversions. Regional land units can vary by jurisdiction; use only a locally verified factor for region-dependent units such as bigha.
