1. What is the Fuel Tank Volume Calculation?

The fuel tank volume calculation estimates the gallon capacity of a car's fuel tank assuming a rectangular shape. This is useful for custom fuel tanks or when specifications aren't available.

2. How Does the Calculator Work?

The calculator uses the volume formula:

\[ V = (L \times W \times H) \times 7.48 \]

Where:

Explanation: The formula calculates the cubic volume then converts it from cubic feet to gallons (1 cubic foot = 7.48 gallons).

3. Importance of Fuel Tank Calculation

Details: Knowing your fuel tank capacity helps in trip planning, fuel efficiency calculations, and when modifying or replacing a fuel tank.

4. Using the Calculator

Tips: Measure the interior dimensions of your fuel tank in feet. For irregular shapes, use average dimensions or divide into rectangular sections.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It's accurate for rectangular tanks. For irregular shapes, it provides an estimate. Actual capacity may vary due to tank shape and internal components.

Q2: Why use 7.48 as the conversion factor?
A: 7.48 gallons equals 1 cubic foot. This is the standard conversion for US liquid gallons.

Q3: Should I measure internal or external dimensions?
A: Always measure internal dimensions for accurate volume calculation, as tank walls take up space.

Q4: Can this be used for other liquids?
A: Yes, the calculation works for any liquid, though the result will be in US gallons.

Q5: How do I measure a cylindrical tank?
A: For cylindrical tanks, use the formula: V = π × r² × h × 7.48, where r is radius and h is height.
