About this calculator

Use this to compare a US window sticker with a European brochure, or a road-trip log that mixed the two. Type the economy number and say whether it is mpg or L/100 km.

L/100 km = 235.214583 / mpg, using the US gallon. UK mpg is different (imperial gallon). Zero or negative economy is rejected. Both results are always shown.

Value: The economy number from the sticker or the trip computer.

From: mpg if the number is miles per US gallon; L/100 km if it is litres per 100 km.

mpg (US): Miles per US gallon.

L/100 km: Litres per 100 kilometres.
