1. What is Tank Gallon Capacity?

Tank gallon capacity refers to the volume of liquid a rectangular tank can hold, measured in US gallons. This calculation is essential for various applications including water storage, fuel tanks, aquariums, and industrial containers.

2. How Does the Calculator Work?

The calculator uses the standard volume formula for rectangular tanks:

Where:

• \( L \) — Length of the tank in inches
• \( W \) — Width of the tank in inches
• \( H \) — Height of the tank in inches
• \( 231 \) — Conversion factor (cubic inches to US gallons)

Explanation: The formula calculates the volume in cubic inches and converts it to US gallons using the standard conversion factor of 231 cubic inches per gallon.

3. Importance of Tank Capacity Calculation

Details: Accurate tank capacity calculation is crucial for proper sizing of storage systems, determining fill times, calculating chemical dosing, and ensuring compliance with safety regulations.

4. Using the Calculator

Tips: Enter all dimensions in inches. Measure the internal dimensions of the tank for accurate results. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why use 231 as the conversion factor?
A: 231 cubic inches equals exactly 1 US gallon, which is the standard conversion used in the United States.

Q2: Can I use this for cylindrical tanks?
A: No, this calculator is specifically for rectangular tanks. Cylindrical tanks require a different formula using radius and height.

Q3: Should I measure inside or outside dimensions?
A: Always measure internal dimensions for accurate capacity calculation, as tank walls have thickness.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise for perfect rectangular shapes. Real-world factors like tank irregularities and internal components may affect actual capacity.

Q5: Can I convert to imperial gallons?
A: For imperial gallons, use 277.42 cubic inches per imperial gallon instead of 231.
