About Liters per Mile
Liters per mile (L/mi) combines the SI litre with the statute mile. 1 L/mi = 100/1.609344 = 62.137 L/100km - an extreme consumption scale. A vehicle consuming 1 L/mi burns as much as a car doing 62 L/100km (equivalent to large agricultural machinery or construction equipment). In endurance motorsport, race engineers convert telemetry fuel-flow (L/s) and lap distance (measured in miles) into L/mi for refuelling window calculations. An M1 Abrams tank consuming 3.3 L/km corresponds to 0.053 L/mi. 1 L/mi = 62.137 L/100km.
