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.
