Fuel economy Converter
Fuel economy uses both linear and inverse units. Miles per gallon (US or UK) and kilometers per liter increase as efficiency improves, while liters per 100 km decreases. These converters apply the correct relationship so a 30 MPG car is not treated like a simple scale factor into L/100km.
