About Kilometers per Liter
Kilometers per liter (km/L) is the standard fuel economy unit in Japan, South Korea, India, Indonesia, Brazil, and most of Latin America and Southeast Asia. Japan's WLTC test cycle certifies fuel economy in km/L under JIS D 1012. Representative WLTC values: Toyota Prius ~26-32 km/L; Honda Jazz hybrid ~28-36 km/L; Hyundai Tucson petrol ~11-14 km/L; Royal Enfield Bullet 350 (India) ~35-42 km/L; 50cc scooter ~40-55 km/L. Hypermiling records: a Prius exceeding 80 km/L. 1 km/L = 100/(km/L value) L/100km = 2.352 mpg(US).
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).
