1. What is the Fuel Oil Tank Capacity Formula?

The fuel oil tank capacity formula calculates the volume of a rectangular tank in gallons from its dimensions in feet. The formula accounts for the conversion from cubic feet to gallons (1 cubic foot = 7.48 gallons).

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 volume in cubic feet (L × W × H) then converts it to gallons by multiplying by 7.48.

3. Importance of Tank Capacity Calculation

Details: Knowing your fuel oil tank capacity helps with inventory management, ordering the correct amount of fuel, and understanding your storage limitations.

4. Using the Calculator

Tips: Measure the interior dimensions of your tank in feet. Enter length, width, and height. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my tank isn't rectangular?
A: This calculator is for rectangular tanks only. Cylindrical tanks require a different formula (π × r² × h × 7.48).

Q2: How accurate is this calculation?
A: It's accurate for perfect rectangular tanks. Real-world tanks may have internal structures reducing actual capacity.

Q3: Should I measure inside or outside dimensions?
A: Always use inside dimensions for accurate capacity calculation.

Q4: What's the typical size of a home fuel oil tank?
A: Common residential tanks hold 275-500 gallons, often measuring about 27"W × 44"H × 60"L for a 275-gallon tank.

Q5: How do I convert inches to feet for measurement?
A: Divide inches by 12 to get feet (e.g., 27 inches = 2.25 feet).
