Frequently Asked Questions

How is fuel cost calculated for a trip?

In metric units: divide the distance (km) by 100, then multiply by your fuel efficiency (L/100 km) to get liters needed, then multiply by the price per liter. In imperial units: divide the distance (miles) by your MPG to get gallons needed, then multiply by the price per gallon.

What is a good fuel efficiency?

For metric, a typical car uses 7–10 L/100 km; a fuel-efficient car uses 4–6 L/100 km. For imperial, 25–35 MPG is average; above 40 MPG is considered efficient.

How do I convert MPG to L/100 km?

Use the formula: L/100 km = 235.21 ÷ MPG. For example, 30 MPG ≈ 235.21 ÷ 30 ≈ 7.84 L/100 km.
