Fuel Cost Calculator – Quick Cheat Sheet

Total distance = one-way distance × (2 if round trip) × trips.
Fuel used (MPG): gallons = total miles ÷ MPG; liters = gallons × 3.785411784.
Fuel used (L/100 km): liters = total km × (L/100 km ÷ 100); gallons = liters ÷ 3.785411784.
Cost = fuel used × price (per gallon or per liter, converted as needed).
Units: 1 mile = 1.609344 km; 1 gallon = 3.785411784 L (U.S. liquid).
