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 Nautical Miles per Liter
Nautical miles per liter (nmi/L) quantifies how far a vessel travels on one liter of fuel. 1 nmi/L = 1.852 km/L. Typical values: sailing yacht under auxiliary diesel ~0.2-0.5 nmi/L; fast 35-knot catamaran ferry ~0.003-0.008 nmi/L; outboard RIB at planning speed ~0.01-0.04 nmi/L. A sportsboat with a 200 L tank at 0.08 nmi/L has ~16 nmi theoretical range, reduced by 30-40% safety margin. Maritime energy efficiency programs under MARPOL Annex VI reference nmi/L before normalising for cargo capacity. 1 nmi/L = 1.852 km/L.
