Fuel Range Calculator
Estimate how far your boat or vehicle can travel based on tank capacity, fuel burn rate, and speed. View range in NM, miles, and kilometers.
Frequently Asked Questions
How do I calculate my boat’s fuel range?
Divide usable fuel (after reserve) by your fuel burn rate to get operating hours, then multiply by average speed. Learn more at NOAA’s boating fuel guide (NOAA boating).
What’s the typical fuel burn rate for boats?
Gasoline outboards usually burn 0.24 L/h per HP, while diesel inboards average 0.20 L/h per HP. Actual rates vary with load and sea state. See US Energy Information Administration fuel data (EIA gasoline).
How much reserve fuel should I keep?
Keep at least 10–20% as reserve to allow for detours and current changes. This is standard safety guidance per US Coast Guard recommendations (USCG boating).
Can I use this calculator for cars or RVs?
Yes. Select your fuel burn rate and average speed in mph or km/h to estimate range for any vehicle.
How accurate is the Fuel Range Calculator?
It provides a theoretical estimate based on average conditions. Real-world range may vary ±15–25% depending on sea state, current, and efficiency.
