About Kilometers per Liter (km/L)

A measure of vehicle fuel efficiency expressed as kilometers driven per liter of fuel consumed. km/L is the standard fuel-economy unit in India (where it appears on every passenger-car ARAI test result and showroom sticker), Japan (JC08 and the newer WLTP-equivalent JIS test cycle), Brazil (INMETRO PBE-Veicular labeling program), and parts of Southeast Asia. Reference values: a typical small gasoline car achieves 12-18 km/L (about 28-42 US mpg), a fuel-efficient diesel 18-25 km/L, a hybrid 22-30 km/L combined, an electric vehicle isn't typically rated in km/L (uses kWh/100km or km/kWh instead). Higher numbers mean better efficiency. Related units include the inverse L/100km (used in Europe per EU Regulation 1153/2017) and miles per US gallon (used in the US per EPA fuel-economy labels); converting between all three is one of the most common automotive calculations for international travelers, expats, and import enthusiasts. 1 km/L = 2.3521 US mpg = 2.8248 UK mpg = (100 ÷ value) L/100km.

About Miles per Gallon (mpg)

A measure of vehicle fuel efficiency used primarily in the United States and United Kingdom. In the US, "mpg" means miles per US gallon (the value calculators generally default to); in the UK, "mpg" traditionally means miles per Imperial gallon — about 20% higher for the same actual efficiency (since 1 UK gal = 1.201 US gal), a notorious source of trans-Atlantic confusion in automotive journalism. Federal EPA fuel-economy labels (city/highway/combined) and Corporate Average Fuel Economy (CAFE) standards per 49 CFR Part 531 are all stated in US mpg. Reference values: 2025 CAFE-mandated fleet average 49 mpg combined; typical US passenger cars 25-35 mpg combined; full-size pickup trucks 18-22 mpg; hybrids 45-60 mpg; the Toyota Prius (the long-running hybrid benchmark) ~56 mpg combined. EVs are rated in MPGe (miles per gallon of gasoline equivalent) at 33.7 kWh/gal, with EPA-tested Tesla Model 3 RWD ~132 MPGe. Convert mpg to km/L by multiplying by 0.4251; to L/100km via 235.215 ÷ value.
