1. What is the Gallons Per Inch Calculation?

The Gallons Per Inch calculation determines how many gallons of water a cylindrical tank holds per vertical inch of height. This is useful for tank calibration and monitoring liquid levels.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Gallons\_per\_inch = \frac{\pi \times r^2}{231} \]

Where:

\( r \) — Radius of the tank in inches
\( \pi \) — Mathematical constant (~3.14159)
231 — Cubic inches per US gallon

Explanation: The formula calculates the volume of a 1-inch tall cylinder (πr² × height) and converts it from cubic inches to gallons.

3. Importance of the Calculation

Details: Knowing gallons per inch helps in precise liquid measurement, tank calibration, and process control in industrial, agricultural, and water treatment applications.

4. Using the Calculator

Tips: Enter the tank radius in inches. The radius is half of the tank's diameter. The value must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Does this work for non-cylindrical tanks?
A: No, this formula is only for perfect cylinders. Other tank shapes require different calculations.

Q2: Why 231 cubic inches per gallon?
A: This is the standard US gallon volume (231 cubic inches = 1 US liquid gallon).

Q3: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real-world accuracy depends on tank construction precision.

Q4: Can I use this for other liquids besides water?
A: Yes, as long as you're measuring volume (not weight/mass). The result will be in gallons regardless of liquid type.

Q5: What if my tank is in feet instead of inches?
A: Convert feet to inches first (1 foot = 12 inches) before using the calculator.
