About Imperial Gallons per Mile
Imperial gallons per mile is the British counterpart, using the 4.54609 L Imperial gallon. 1 Imp gal/mi = 4.54609/1.609344 × 100 = 282.481 L/100km - among the largest fuel-consumption values in practical use, representing large vessels and heavy machinery. It appears in older Royal Navy vessel technical logs and historical British railway and steam-locomotive records. As mpg(Imp) and gal/mi are reciprocals, a 50 mpg(Imp) car uses exactly 0.02 Imp gal/mi = 5.650 L/100km. 1 Imp gal/mi = 282.481 L/100km.
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).
