About US Gallons per 100 Miles

US gallons per 100 miles is the volumetric consumption figure displayed alongside mpg on the EPA Monroney fuel-economy label on all new US vehicles since 2013. A smaller number means a more efficient car. At $4/gal, gal/100mi × 4 gives the dollar fuel cost per 100 miles. Ranges: 1.5-2 gal/100mi for efficient compacts (50-67 mpg); 2.5-3.5 for mainstream sedans (28-40 mpg); 4-6 for crossovers/light trucks (17-25 mpg). 1 US gal/100mi = 3.785411784/1.609344 = 2.3521 L/100km.

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.
