Fuel Tank Range Calculator
Calculate how far you can drive on a full tank.
Enter your tank size and fuel efficiency to find your maximum driving range.
Maximum Range
Driving range is how far you can travel on a full tank of fuel.
Metric formula:
Range (km) = Tank Size (liters) × Fuel Efficiency (km/L)
Imperial formula:
Range (miles) = Tank Size (gallons) × Fuel Efficiency (mpg)
L/100km formula:
Range (km) = (Tank Size (liters) / L per 100km) × 100
Unit conversions:
- 1 US gallon = 3.785 liters
- 1 imperial gallon = 4.546 liters
- km/L × 2.352 = mpg (US)
- 235.21 / L per 100km = mpg (US)
Typical fuel efficiencies:
- Compact car: 14–18 km/L (33–42 mpg)
- Sedan: 11–15 km/L (26–35 mpg)
- SUV: 8–12 km/L (19–28 mpg)
- Truck/pickup: 6–10 km/L (14–24 mpg)
- Motorcycle: 20–30 km/L (47–70 mpg)
Note: Actual range varies with driving conditions, speed, terrain, A/C usage, and load.
