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.
About Imperial Gallons per Mile
Imperial gallons per mile is the British counterpart, using the 4.54609 L Imperial gallon. 1 Imp gal/mi = 4.54609/1.609344 × 100 = 282.481 L/100km - among the largest fuel-consumption values in practical use, representing large vessels and heavy machinery. It appears in older Royal Navy vessel technical logs and historical British railway and steam-locomotive records. As mpg(Imp) and gal/mi are reciprocals, a 50 mpg(Imp) car uses exactly 0.02 Imp gal/mi = 5.650 L/100km. 1 Imp gal/mi = 282.481 L/100km.
