Convert Kilometers per Imperial Gallon to Milliliters per Kilometer

Convert Kilometers per Imperial Gallon (km/Imp gal) to Milliliters per Kilometer (mL/km) instantly and accurately.

Conversion Formula

mL/km = 4546.09 ÷ km/Imp gal

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 Milliliters per Kilometer

A milliliter per kilometer (mL/km) equals 0.1 L/100km. A compact car at 7 L/100km uses 70 mL/km; a 50cc scooter at 2.5 L/100km uses 25 mL/km; a loaded semi at 35 L/100km uses 350 mL/km. This scale makes proportionality across very different vehicle categories clear without fractional L/100km values. In motorsport, a Formula 3 car consuming ~55 mL/km over a 5.8 km circuit burns ~319 mL/lap, enabling sub-lap pit-stop window planning. CNG and LPG comparison reports also use mL/km of liquid-fuel equivalent. 1 mL/km = 0.1 L/100km.
