Kilometers Per Liter Tips

Kilometers per liter (km/L) is a common fuel efficiency measurement in many countries including Japan and India.
Higher km/L values indicate better fuel efficiency (more distance per unit of fuel).
To convert from kilometers per liter (km/L) to liters per 100km (L/100km), divide 100 by the km/L value.
To convert from km/L to MPG, multiply by 2.352.
For accurate km/L readings, fill your tank completely, record the odometer, drive normally, then refill and divide the kilometers driven by liters used.
For electric vehicles, the equivalent measurement would be kilometers per kilowatt-hour (km/kWh).
