Work out how much fuel a trip takes and what it costs - in L/100 km, km/L or MPG - for one way or a round trip, split between passengers.
Type the distance, your car's fuel consumption and the price at the pump to see how much fuel the trip takes and what it costs. Consumption can be entered the way your car or country shows it - litres per 100 km, km per litre, or miles per gallon (US or UK) - and the price per litre or per gallon. Tick round trip to double the distance, and split the cost between passengers. The page also shows the cost per kilometre or mile and your consumption converted to the other units.
Frequently asked questions
How is fuel cost calculated?
Fuel used = distance × consumption. At 6 L/100 km, 450 km takes 450 × 6 ÷ 100 = 27 litres. Multiply by the price per litre for the cost: 27 × 1.80 = 48.60.
Where do I find my car's consumption?
Most cars show the average on the dashboard or trip computer. For a real figure, fill the tank, drive, fill it again and divide the litres you put in by the kilometres driven, times 100. Official figures are usually optimistic by 10-20%.
What's the difference between US and UK MPG?
A UK (imperial) gallon is 4.546 litres, a US gallon 3.785 litres - so the same car gets about 20% more MPG on the UK scale. 30 MPG (US) is 7.8 L/100 km, while 30 MPG (UK) is 9.4 L/100 km.
