FUEL EFFICIENCY
	unit	unit- code		notes		combinations
	kilometres per litre	km/l (km/L)		Use km/L to get "km/L"		km/l mpgimp km/l mpgus
	litres per 100 kilometres	l/100 km (L/100 km)		Use L/100 km to get "L/100 km"		l/100 km mpgimp l/100 km mpgus

	miles per imperial gallon	mpgimp				mpgimp mpgus
	miles per US gallon	mpgus (mpgUS, mpgU.S.)		Use mpgUS to get "US" Use mpgU.S. to get "U.S." mpgus will give "U.S." if spelling is set to US & "US" otherwise		mpgus mpgimp
	imperial gallons per mile	impgal/mi				impgal/mi
	US gallons per mile	usgal/mi (USgal/mi, U.S.gal/mi)		As above with the us vs US vs U.S.		usgal/mi
The mpgUS, mpgU.S., USgal/mi vs U.S.gal/mi, km/L, L/100 km and L/km variants work within combinations also (making 36 combinations in total).
