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 Nautical Mile
Liters per nautical mile (L/nmi) is the maritime fuel consumption unit. One nautical mile = 1.852 km exactly (one arcminute of latitude). A large container ship (400 m, 200,000 DWT) at 18 knots consumes 50,000-100,000 L/nmi of heavy fuel oil; a RoPax ferry 800-3,000 L/nmi; a RIB patrol boat at 25 knots 30-80 L/nmi. Slow-steaming reduces L/nmi by 30-40% due to the cubic drag-speed relationship. Bunker cost per nmi = L/nmi × fuel price/litre. 1 L/nmi = 100/1.852 ≈ 53.996 L/100km.
