Fuel Consumption Converter

Convert vehicle fuel efficiency and consumption between all common units with correct handling of reciprocal relationships. Covers Litres/100km (European standard), km/L (Japanese/Asian standard), mpg US (American standard), mpg UK (British Imperial), L/km, L/mile, miles/litre, gallons(US)/100mi, and gallons(UK)/100mi. Correctly handles the fact that L/100km and mpg are reciprocal (higher L/100km = worse; higher mpg = better), unlike simple unit conversions. Clearly shows the US vs UK gallon difference (1 UK gallon = 1.2009 US gallons). Includes a quick reference table with common mpg-to-L/100km equivalents. Adjustable significant figures. All conversions are instantaneous and browser-based.
