Fuel cost calculator
Estimate fuel quantity and cost for a trip.
Formula
Fuel L = km × (L/100 km) / 100; cost = fuel / priced volume × price
Trip distance: 300 mi · Fuel consumption / economy: 30 mpg (US) · Volume bought at that price: 1 US gal · Fuel needed ≈ (300 mi × 1,609.344 m/mi)÷100000×(235.214583 L/100 km·mpg (US) ÷ 30 mpg (US)) · Trip fuel cost ≈ (37.85411779)÷(1 US gal × 3.785411784 L/US gal)×(3.5)
How to use
- Enter trip distance and consumption.
- Enter price and the volume that price buys.
- Read fuel needed and trip cost.
Examples
- 500 km at 8 L/100 km needs 40 L; at 2 per liter it costs 80.
