Frequently Asked Questions
Does the calculator support metric units?
Yes. Switch between miles/mpg and kilometers/L per 100 km using the unit toggle to match your region's fuel economy standard.
How is the fuel cost calculated?
Total fuel needed = Distance ÷ Fuel Efficiency. Total cost = (Total fuel × Gas Price) + Tolls. Cost per person = Total cost ÷ Number of passengers.
Can I calculate round-trip costs?
Yes. Toggle the Round Trip option and the distance is doubled before the fuel cost is computed.
Is my data sent to a server?
No. All calculations run in your browser; nothing is uploaded or stored.
