How do I estimate trip fuel cost?

Divide the distance by your fuel efficiency to get the fuel used, then multiply by the price per liter or gallon. The calculator also works backward from a budget to find how far you can go.

Does it support both mpg and L/100km?

Yes — the calculator accepts miles per gallon, liters per 100 km, and kilometers per liter, and converts between them automatically.
