Fuel Efficiency Converter
Convert vehicle fuel economy between km/L, US MPG, Imperial UK MPG, and L/100km.
A fuel efficiency converter translates vehicle gas mileage across km/L, US MPG, Imperial MPG, and L/100km. To convert US MPG to km/L, divide by 2.352. To convert US MPG to L/100km, calculate 235.215 / MPG. 30 US MPG equals 12.75 km/L (7.84 L/100km).
Accounts for both direct distance-per-volume ratios (MPG, km/L) and inverse volume-per-distance metrics (L/100km).
