About Imperial Gallons per 100 Miles
Imperial gallons per 100 miles is the British volumetric consumption equivalent using the Imperial gallon (4.54609 L). Since the Imperial gallon is ~20.1% larger than the US gallon, a vehicle's Imp gal/100mi is correspondingly smaller than its US gal/100mi. A car at 7 L/100km needs 2.977 US gal/100mi but only 2.478 Imp gal/100mi. The unit appears in UK fleet management software and automotive engineering reports. A 50 mpg(Imp) car uses 2 Imp gal/100mi = 5.650 L/100km. 1 Imp gal/100mi = 4.54609/1.609344 = 2.8248 L/100km.
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.
