About Liters per 100 Kilometers

Liters per 100 kilometers (L/100km) is the standard fuel consumption unit of the EU, China, Australia, and most of the world. Lower values mean greater efficiency: 5 L/100km is exactly twice as efficient as 10 L/100km. EU WLTP certification requires reporting in L/100km; CO₂ in g/km ≈ L/100km × 23.9 (petrol) or × 26.5 (diesel). Benchmarks: European average new car (2024 WLTP) ~6.5 L/100km; compact SUV 8-11; articulated truck 28-35; M1 Abrams tank ~130. 1 L/100km = 235.215/mpg(US) = 282.481/mpg(Imp).

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.
