How to convert Mile per gallon (US) to Kilometer per litre

Conversion factor and calculation steps from Mile per gallon (US) (mpg US) to Kilometer per litre (km/L).

Conversion logic

Consumption and economy are inverse: a higher mpg means fewer litres per 100 km.

mpg US = 235.214583333 ÷ (L/100 km)

km/L = 100 ÷ (L/100 km)

235.214583333 ÷ 1 mpg US = 235.214583333 L/100 km

100 ÷ 235.214583333 = 0.42514370743 km/L
