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.

About Liters per Kilometer

Liters per kilometer (L/km) is 100× larger than L/100km, suited to heavy vehicles and industrial machinery. A European family car at 0.07 L/km; a Class 8 semi-truck 0.33-0.40 L/km; an M1 Abrams tank ~1.3 L/km on road, ~4 L/km off-road; a diesel mainline locomotive 5-8 L/km. Australian road trains (200+ t) log fuel in L/km to plan outback depot spacing. A Caterpillar 793F mining dump truck fully laden uses 4-6 L/km. 1 L/km = 100 L/100km.
