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 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.
