Fuel economy is quoted as either Miles per Gallon (MPG) or Kilometres per litre (Km/L). In the UK we use imperial units for distance but metric units for volume. This is a simple application to calculate the MPG for the previous tank of petrol.
The app also does straightforward calculations in Imperial (MPG) and metric (KmL & L/100K)
Enter the miles travelled for the last tank of petrol and then either the number of litres or the cash value of petrol and the price per litre. The program will calculate the volume of petrol used and convert it to Gallons. The MPG value is then displayed.
Values are automatically stored into a database , you can view your history as a graph or in a simple table.
