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 Miles per US Gallon
Miles per US gallon (mpg(US)) is the US and Canadian standard, displayed on every EPA Monroney sticker and used in CAFE regulations. The US gallon = 3.785411784 L; 1 mile = 1.609344 km. 2026 CAFE passenger car standard: ~49 mpg. Toyota Prius Prime: 52 mpg; Tesla Model 3: 132 MPGe. Historical: Ford Model T 21-25 mpg; 1973 US full-size cars 10-15 mpg. NASCAR at race speed: 4-5 mpg; Class 8 semi: 5-8 mpg. L/100km = 235.21458/mpg(US): 30 mpg = 7.84 L/100km; 50 mpg = 4.71 L/100km.
