Fuel Rate Calculator

Formatting only. This does not change the calculation.
Odometer difference between two fill-ups. Used in "distance and fuel used" mode, and as the trip length when converting.
Volume needed to refill the tank after that distance.
Price per unit of the fuel volume unit above (per US gallon, per imperial gallon or per litre).

How this is worked out

5 steps
  1. Distance 350 km = 350 km; fuel 12.5 L = 12.5 L.
  2. Economy = 350 km / 12.5 L = 28 km/L.
  3. 28 km/L = 3.571429 L/100km.
  4. Fuel for 350 km = 350 km / 28 km/L = 12.5 L = 12.5 L.
  5. Cost = 12.5 L x 3.6 = 45, i.e. 0.1286 per km.
