About Kilometers per US Gallon

Kilometers per US gallon (km/US gal) appears in regions where metric road distances coexist with US gallon fuel pricing - the US-Mexico border zone, parts of Latin America, and the Caribbean. 1 km/US gal = 1/3.785411784 km/L = 0.264172 km/L. A typical car at 12.75 km/L = 48.3 km/US gal; a scooter at 35 km/L = 132 km/US gal. Mexican Federal District fleet databases and Central American logistics records use this unit when US gallon fuel costs are referenced in kilometre-based route planning. 1 km/US gal = 0.264172 km/L.

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).
