How to Calculate Vehicle Mileage
The mileage calculator above uses a simple formula: divide the total distance driven by the fuel consumed. If you drove 400 km and used 28 litres of petrol, your mileage is 400 ÷ 28 = 14.3 km/l. This real-world measurement is far more reliable than manufacturer-claimed ARAI figures.
Understanding Mileage Units — km/l vs MPG
In India, fuel efficiency is measured in km/l (kilometres per litre). The US uses MPG (miles per gallon), while Europe prefers L/100 km (lower is better). When comparing vehicles across countries — for instance, checking if an imported car is efficient — our mileage converter translates between all four standards instantly.
Convert Mileage to Kilometres
A common search is "mileage converter to km" — users want to know how far they can drive with a given amount of fuel. Use the "Mileage → Distance" mode above: enter your vehicle's known mileage and the fuel in your tank, and it calculates the total range in kilometres. For example, 15 km/l × 35 litres = 525 km.
What Is Good Mileage?
Good mileage varies by vehicle type. For a petrol car in India, 14–20 km/l is considered good. Diesel cars typically deliver 18–25 km/l. Bikes range from 35–65 km/l depending on engine size. SUVs are lower at 8–15 km/l, and commercial trucks average 3–6 km/l. The gauge in our mileage estimator benchmarks your result against these ranges.
Tips to Improve Mileage
Consistent speeds between 45–60 km/h yield the best efficiency. Keep tyres at recommended pressure (under-inflation alone can reduce mileage by 3–5%). Regular servicing, smooth acceleration, reduced AC use, and lighter loads all contribute. Tracking mileage monthly helps you spot problems early — a sudden drop often signals engine or tyre issues.
