Mileage Calculator — Free Online (Tolyo.app)
Average mileage & cost per km/mi.
Unit matches selected fuel unit (L)
Results are estimates. Real-world mileage depends on vehicle condition, load, speed, and traffic.
How the Tolyo.app Mileage Calculator Works
Enter your distance traveled and fuel used to get average mileage in km/L and MPG, plus the efficiency format many drivers use internationally —L/100km. Add a fuel price to reveal total trip cost and cost per km/mi.
Formulas (client-side only)
- • Mileage (km/L) = distance (km) ÷ fuel (L)
- • L/100km = (fuel (L) ÷ distance (km)) × 100
- • MPG (US) = mileage (km/L) × 2.352
- • Trip cost = fuel used × price per unit
- • Cost per km/mi = trip cost ÷ distance
Tips for More Accurate Mileage
- • Fill the tank to the same level each time and reset the trip meter.
- • Use longer trips to average out city/traffic variation.
- • Check tire pressure, driving speed, and air-conditioning usage — they affect fuel economy.
Informational only — values vary by driving style, terrain, vehicle condition, and weather.
