Estimate fuel needed, trip cost and cost per passenger using metric or US units.
Fuel economy is treated as distance per unit of fuel: km/L in metric mode and miles per US gallon in US mode.
Fuel needed equals trip distance divided by fuel economy. Multiply the required fuel by the price per liter or gallon to estimate total trip fuel cost.
Metric mode uses kilometers per liter. US mode uses miles per US gallon. Switching modes converts the current values so the same trip remains approximately equivalent.
No. Metric fuel economy is entered as km/L. If your vehicle reports L/100 km, divide 100 by that value to get km/L.
US mode uses the US liquid gallon, not the Imperial gallon.
Total estimated fuel cost is divided equally by the number of passengers you enter.
