About this conversion
Kilometers per liter and US gallons per 100 miles are both units used to measure fuel economy. 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 (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 is a distance-per-volume efficiency unit while us gallons per 100 miles is a volume-per-distance consumption unit, so converting between them means inverting the value rather than multiplying by a flat factor: 1 km/L = 42.51437074 gal/100 mi. This relationship stays accurate for automotive fuel efficiency ratings, vehicle comparisons and shopping, as well as EPA, WLTP and other international fuel economy standards.
