The SI derived unit for fuel consumption is: meter per cubic meter (m/m³)
1 mile per gallon (U.S) (mi/gal) = 425 143.7 meter per cubic meter (m/m³)
1 mile per gallon (U.S) (mi/gal) = 0.425 143 7 kilometer per liter (km/L)
1 liter per 100 kilometer (L/100km) = 235.215 mile per gallon (U.S) (mi/gal)
Units mainly used in car industry to measure fuel consumption of engines. Units used for measuring fuel consumption are volume per distance (like: gallons per 100 miles) or distance per volume (like: kilometers per liter). The following table halps to convert between various fuel consumption units. L - liter can be changed to any volume unit like gallon or cubic meter e.g X is the value to be converted.
Fore example: convert 4 liter per 100 kilometer [L/100km] into liter per kilometer [L/km] and kilometers per liter [km/L].
