About this conversion
US gallons per 100 miles and Kilometers per liter are both units used to measure fuel economy. US gallons per 100 miles (gal/100 mi) measures how many US gallons of fuel a vehicle consumes over 100 miles; a lower number means better efficiency. It is occasionally used in the United States for consumption-style comparisons. Kilometers per liter (km/L) measures how many kilometers a vehicle travels using one liter of fuel; a higher number means better efficiency. It is a common metric fuel economy unit. US gallons per 100 miles is a distance-per-volume efficiency unit while kilometers per liter is a volume-per-distance consumption unit, so converting between them means inverting the value rather than multiplying by a flat factor: 1 gal/100 mi = 42.51437074 km/L. This relationship stays accurate for automotive fuel efficiency ratings, vehicle comparisons and shopping, as well as EPA, WLTP and other international fuel economy standards.
