How it works
Fuel used = (distance ÷ 100) × consumption in L/100 km, and cost = fuel used × price per litre. All three inputs are yours.
Assumptions & limits
- Consumption is entered as litres per 100 km; price as currency per litre.
- Distance, consumption and fuel price are all user-supplied.
§
FAQ
- Can I use mpg instead?
- This tool uses L/100 km and price per litre. Convert your figures first, or use the fuel-economy converter.
