How Distance from Fuel Calculator Works
This tool works by multiplying available fuel by fuel economy to show how far the vehicle can travel.
- Step 1
Enter available fuel
Type the gallons or liters available in the tank or a container.
- Step 2
Enter fuel economy
Type MPG, km/L, or L/100 km.
- Step 3
Apply a safety margin
Choose a margin, such as 10%, for hills and detours.
- Step 4
Read the distance
The calculator shows the full range and the range after the safety margin.
Distance from Fuel Calculator Formula
The formula multiplies fuel by MPG, or divides liters by L/100 km and multiplies by 100.
Distance (mi) = Gallons × MPG
Distance (km) = Liters ÷ L/100 km × 100
Safe Distance = Distance × (1 − Margin %)
- Gallons, Liters
- = fuel available
- Margin %
- = share of range held back for safety
Worked Example
- A driver has 6.5 gallons (24.6 liters) left in a 28 MPG (8.4 L/100 km) car.
- Distance = 6.5 × 28 = 182 miles (293 km).
- Safe distance with a 10% margin = 163.8 miles (264 km).
- A 150-mile drive fits within the safe distance.
Distance from Fuel Calculator Conversion Table
The table lists driving distance in miles for common fuel amounts and fuel economy ratings.
| Fuel (gal / L) | 15 MPG | 20 MPG | 25 MPG | 30 MPG | 40 MPG | 50 MPG |
|---|---|---|---|---|---|---|
| 1 / 3.8 | 15 | 20 | 25 | 30 | 40 | 50 |
| 2 / 7.6 | 30 | 40 | 50 | 60 | 80 | 100 |
| 5 / 18.9 | 75 | 100 | 125 | 150 | 200 | 250 |
| 8 / 30.3 | 120 | 160 | 200 | 240 | 320 | 400 |
| 10 / 37.9 | 150 | 200 | 250 | 300 | 400 | 500 |
| 15 / 56.8 | 225 | 300 | 375 | 450 | 600 | 750 |
| 20 / 75.7 | 300 | 400 | 500 | 600 | 800 | 1,000 |
Multiply miles by 1.609 for kilometers. One US gallon (3.785 L) in a 30 MPG car covers 30 miles (48.3 km). A 30 MPG rating equals 12.8 km/L and 36.0 imperial MPG.
What is a Distance from Fuel Calculator?
A Distance from Fuel Calculator is a range tool that calculates how far a vehicle can travel on a known amount of fuel.
Drivers need a distance answer in 3 common moments: the fuel light comes on, a jerry can is the only fuel left, or a remote route has a long gap between stations. The Distance from Fuel Calculator turns fuel on hand into miles or kilometers.
The safety margin protects against lower-than-expected fuel economy from hills, wind, and heavy loads.
What are the uses of a Distance from Fuel Calculator?
There are 4 main uses of the Distance from Fuel Calculator, including low-fuel decisions, jerry can planning, and generator-to-vehicle checks.
Decide on low fuel
Check whether the next station is within reach.
Plan with spare fuel
See how far a 5-gallon (19 L) can takes the vehicle.
Check remote routes
Compare range with the gap between stations.
Plan small-engine use
Estimate ATV, boat, or mower range from fuel on hand.
