Convert Kilometers per Imperial Gallon to Nautical Miles per Liter
Convert Kilometers per Imperial Gallon (km/Imp gal) to Nautical Miles per Liter (nmi/L) instantly and accurately.
Conversion Formula
nmi/L = km/Imp gal × 8.41935868
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 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.
