What is Fuel Cost Calculator?
Knowing the fuel cost of a trip helps you budget, compare driving with other travel, and share costs with passengers.
What this tool does
The first part multiplies the distance by your fuel use to find the litres needed, then multiplies by the price. The second part converts miles per US gallon to litres per 100 km, kilometres per litre and miles per UK gallon.
How to use it
- Enter the distance, the fuel use in litres per 100 km and the price per litre.
- Read the fuel needed and the cost.
- Use the second part to convert from mpg.
Did you know?
- A US gallon is smaller than a UK gallon, so the same car shows a higher mpg figure in the UK.
- Driving fast, carrying heavy loads and cold weather all raise fuel use.
