km/L = mpg × 0.425144Formula
mpg = km/L × (235.214583333 / 100) (constants shown rounded)Multiply km/L by 2.35215 to get US mpg. The factor is 3.785411784 L per US gallon divided by 1.609344 km per mile, written in the formula as 235.214583 / 100. Japanese, Indian, and many Latin American sources rate cars in km/L, while US buyers compare mpg. A car rated 15 km/L equals about 35.28 mpg. Test cycles differ between regions, so a converted figure will not match the number on a US window sticker.
