About Miles per Imperial Gallon
Miles per Imperial gallon (mpg(Imp)) is the UK and historically Commonwealth standard. The Imperial gallon (4.54609 L) is ~20.1% larger than the US gallon, so mpg(Imp) is always numerically higher: a 7 L/100km car achieves 33.6 mpg(US) but 40.4 mpg(Imp). All UK VCA-certified specs list mpg(Imp). Typical WLTP combined: supermini 45-60 mpg; full hybrid 55-75 mpg; diesel family car 48-68 mpg; large petrol SUV 28-38 mpg. 1 mpg(Imp) = 1.609344/4.54609 km/L = 0.354006 km/L; L/100km = 282.481/mpg(Imp).
About Miles per Liter
Miles per liter (mi/L) appears in regions where fuel is dispensed in liters but road distances follow older imperial maps - parts of Sub-Saharan Africa, the Middle East, and South Asia. 1 mi/L = 1.609344 km/L. A car at 10 mi/L = 16.09 km/L = 37.85 mpg(US). India's auto press used mi/L before metrication; some Pakistani logistics companies still use it for long-haul route-efficiency reports. Converting: mpg(US) = mi/L × 3.785411784; mpg(Imp) = mi/L × 4.54609. 1 mi/L = 1.609344 km/L.
