About Kilometers per Imperial Gallon

Kilometers per Imperial gallon (km/Imp gal) combines metric distances with the British Imperial gallon (4.54609 L). 1 km/Imp gal = 1/4.54609 km/L = 0.21997 km/L. A typical mid-size car at 12.75 km/L = 57.96 km/Imp gal. It appears in pre-1970s Australian road transport regulations, some South African vehicle import documentation, and pre-1979 Canadian fuel efficiency standards. Relationship to mpg(Imp): km/Imp gal = mpg(Imp) / 1.609344, so 50 mpg(Imp) = 31.07 km/Imp gal. 1 km/Imp gal = 0.21997 km/L.

About Liters per Kilometer

Liters per kilometer (L/km) is 100× larger than L/100km, suited to heavy vehicles and industrial machinery. A European family car at 0.07 L/km; a Class 8 semi-truck 0.33-0.40 L/km; an M1 Abrams tank ~1.3 L/km on road, ~4 L/km off-road; a diesel mainline locomotive 5-8 L/km. Australian road trains (200+ t) log fuel in L/km to plan outback depot spacing. A Caterpillar 793F mining dump truck fully laden uses 4-6 L/km. 1 L/km = 100 L/100km.
