1. What is the Cylinder Volume Formula?

The cylinder volume formula calculates the capacity of a cylindrical container in US gallons. This is particularly useful for tanks, barrels, and other cylindrical containers in industrial, agricultural, and household applications.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

\[ \text{Gallons} = \frac{\pi \times r^2 \times h}{231} \]

Where:

\( \pi \) — Approximately 3.14159
\( r \) — Radius of the cylinder (inches)
\( h \) — Height of the cylinder (inches)
231 — Cubic inches per US gallon

Explanation: The formula calculates the volume in cubic inches (πr²h) and converts it to US gallons by dividing by 231 cubic inches per gallon.

3. Importance of Volume Calculation

Details: Accurate volume calculation is essential for determining storage capacity, mixing ratios, and filling levels in cylindrical containers across various industries.

4. Using the Calculator

Tips: Measure the radius and height in inches. The radius is half of the diameter. All values must be positive numbers.

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 this for metric measurements?
A: No, this calculator is specifically for inches to US gallons. For metric, you would use different units (cm or m to liters).

Q3: What if my cylinder isn't perfect?
A: This calculation assumes a perfect cylinder. For irregular shapes, more complex calculations are needed.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise for perfect cylinders. Accuracy depends on your measurements.

Q5: Can I calculate partial fills?
A: Yes, just use the actual liquid height for the h value in the formula.
