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
litres per kilometre l/km (L/km) Use L/km to get "L/km"
  • l/km impgal/mi
  • l/km usgal/mi
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).
