1. What is a Cylinder Tank Volume Calculator?

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

Purpose: It helps professionals and DIYers determine the liquid capacity of cylindrical containers used in various industries.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{gal} \) — Volume in gallons
• \( r \) — Radius of the cylinder (inches)
• \( h \) — Height of the cylinder (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, fuel tanks, and water systems.

4. Using the Calculator

Tips: Measure the radius and height in inches (diameter ÷ 2 = radius). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: There are 231 cubic inches in one US gallon, which is the standard conversion factor.

Q2: Can I use diameter instead of radius?
A: Yes, but you'll need to divide diameter by 2 first (radius = diameter/2).

Q3: Does this work for horizontal tanks?
A: No, this calculator is for vertical cylindrical tanks only.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders, but actual tanks may have variations.

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