1. What is a Rectangle Fuel Tank Calculator?

Definition: This calculator estimates the volume of a rectangular fuel tank in gallons based on its dimensions in inches.

Purpose: It helps engineers, mechanics, and tank designers determine the capacity of rectangular fuel tanks.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{gal} = \frac{L \times W \times H}{231} \]

Where:

\( V_{gal} \) — Volume in gallons
\( L \) — Length of tank (inches)
\( W \) — Width of tank (inches)
\( H \) — Height of tank (inches)

Explanation: The formula calculates cubic inches first, then converts to gallons (1 gallon = 231 cubic inches).

3. Importance of Fuel Tank Volume Calculation

Details: Accurate volume calculation ensures proper fuel storage capacity planning, compliance with regulations, and efficient space utilization.

4. Using the Calculator

Tips: Measure the internal dimensions of your tank in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: 231 cubic inches equals 1 US liquid gallon, which is the standard conversion factor.

Q2: Can I use this for other liquids?
A: Yes, this calculates total volume. For actual capacity, consider leaving 10-15% headspace.

Q3: What if my tank has irregular shapes?
A: This calculator is for rectangular tanks only. For cylindrical tanks, use a different calculator.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect rectangles. Real tanks may vary slightly due to manufacturing tolerances.

Q5: Can I use centimeters instead of inches?
A: First convert cm to inches (1 inch = 2.54 cm) or modify the formula to use 3785.41 (cubic cm per gallon).
