1. What is a Gallon Volume Calculator for Cylinder?

Definition: This calculator estimates the volume of a cylinder in gallons based on its radius and height measurements in inches.

Purpose: It helps professionals and DIYers determine liquid capacity of cylindrical containers like tanks, pipes, or barrels.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{gal} \) — Volume in gallons
• \( r \) — Radius in inches
• \( h \) — Height in inches
• \( 231 \) — Conversion factor (cubic inches per gallon)

Explanation: The formula calculates the cylindrical volume in cubic inches then converts to gallons.

3. Importance of Cylinder Volume Calculation

Details: Accurate volume calculations are essential for liquid storage, chemical processing, and industrial applications.

4. Using the Calculator

Tips: Enter the radius and height in inches. Both values must be > 0. The result will be in US gallons.

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use different units?
A: This calculator requires inches. For other units, convert to inches first.

Q3: Does this work for horizontal cylinders?
A: This formula is for vertical cylinders. Horizontal cylinders require more complex calculations.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real-world containers may vary slightly.

Q5: What about irregular shapes?
A: This calculator is for regular cylinders only. Different formulas are needed for irregular shapes.
