How to calculate
Estimate distance from fuel remaining after setting aside a reserve.
Range in km = (fuel remaining − reserve) ÷ consumption × 100.
Worked example
Usable fuel remaining (litres): 45; Fuel reserve to keep (litres): 5; Consumption (L/100 km): 7.
Estimated remaining range: 571.43 km; Estimated remaining range: 355.07 miles.
Assumptions and limits
Estimate distance from fuel remaining after setting aside a reserve. Consumption varies with traffic, terrain and load; this is not a guarantee that fuel will last to a destination.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Estimate distance from fuel remaining after setting aside a reserve. Consumption varies with traffic, terrain and load; this is not a guarantee that fuel will last to a destination.
When this tool is useful
Range in km = (fuel remaining − reserve) ÷ consumption × 100.
Understanding your inputs
| Input | What to enter |
|---|---|
| Usable fuel remaining (litres) | Enter a number of at least 0 and no more than 1000000000000. |
| Fuel reserve to keep (litres) | Enter a number of at least 0 and no more than 1000000000000. |
| Consumption (L/100 km) | Enter a number of at least 0.001 and no more than 1000000000000. |
Frequently asked questions
Should I use the whole fuel tank in the range estimate?
Set aside a reserve before calculating. The result uses fuel remaining after that reserve and assumes the entered average consumption stays constant; real conditions can shorten the range.
