1. What is the Fuel Tank Measurement Formula?

The fuel tank measurement formula calculates the volume of a rectangular fuel tank in gallons. It multiplies the length, width, and height (in feet) and then converts cubic feet to gallons using the conversion factor 7.48 gallons per cubic foot.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume in gallons
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( H \) — Height in feet
• 7.48 — Conversion factor (gallons per cubic foot)

Explanation: The formula first calculates the cubic feet of the tank by multiplying the three dimensions, then converts to gallons since fuel is typically measured in gallons.

3. Importance of Accurate Fuel Tank Measurement

Details: Accurate fuel tank measurement is crucial for determining fuel capacity, planning refueling schedules, calculating fuel economy, and managing fuel inventory for truck fleets.

4. Using the Calculator

Tips: Measure the internal dimensions of your fuel tank in feet. Enter length, width, and height as decimal numbers (e.g., 2.5 feet). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 7.48?
A: There are 7.48052 gallons in one cubic foot. The calculator uses this conversion factor to give results in gallons.

Q2: Can I use this for cylindrical tanks?
A: No, this calculator is for rectangular tanks only. Cylindrical tanks require a different formula (π × r² × h × 7.48).

Q3: How accurate is this calculation?
A: It provides theoretical maximum capacity. Actual usable capacity may be less due to tank shape variations, internal components, and safe fill levels.

Q4: Should I measure inside or outside dimensions?
A: Always use internal dimensions for accurate volume calculation, as tank walls have thickness that reduces internal capacity.

Q5: What about irregularly shaped tanks?
A: For complex shapes, you may need to break the tank into regular geometric sections and calculate each separately.
