About Miles per Imperial Gallon
Miles per Imperial gallon (mpg(Imp)) is the UK and historically Commonwealth standard. The Imperial gallon (4.54609 L) is ~20.1% larger than the US gallon, so mpg(Imp) is always numerically higher: a 7 L/100km car achieves 33.6 mpg(US) but 40.4 mpg(Imp). All UK VCA-certified specs list mpg(Imp). Typical WLTP combined: supermini 45-60 mpg; full hybrid 55-75 mpg; diesel family car 48-68 mpg; large petrol SUV 28-38 mpg. 1 mpg(Imp) = 1.609344/4.54609 km/L = 0.354006 km/L; L/100km = 282.481/mpg(Imp).
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.
