1. What is a Tank Gallon Size Calculator?

Definition: This calculator estimates the volume of liquid a tank can hold in gallons based on its dimensions.

Purpose: It helps determine tank capacity for storage, industrial applications, aquariums, or any liquid containment needs.

2. How Does the Calculator Work?

The calculator uses different formulas based on tank shape:

\[ V_{gal} = \frac{L \times W \times H}{231} \text{ (rectangular)} \] \[ V_{gal} = \frac{\pi \times r^2 \times h}{231} \text{ (cylindrical)} \]

Where:

\( V_{gal} \) — Volume in gallons
\( L \) — Length (inches, rectangular tanks)
\( W \) — Width (inches, rectangular tanks)
\( H \) — Height (inches, rectangular tanks)
\( r \) — Radius (inches, cylindrical tanks)
\( h \) — Height (inches, cylindrical tanks)

Explanation: The calculator converts cubic inches to gallons (1 gallon = 231 cubic inches) for accurate volume measurement.

3. Importance of Tank Volume Calculation

Details: Proper tank volume estimation ensures correct sizing for liquid storage, prevents overfilling, and helps in system design.

4. Using the Calculator

Tips: Select tank shape, enter dimensions in inches. All values must be > 0. For cylindrical tanks, measure diameter and divide by 2 for radius.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231 in the formula?
A: There are 231 cubic inches in one US gallon, so this conversion gives volume in gallons.

Q2: Can I use this for irregular shaped tanks?
A: No, this calculator only works for standard rectangular or cylindrical shapes. For irregular shapes, consult a specialist.

Q3: How accurate is this calculation?
A: It provides theoretical maximum capacity. Actual usable volume may be less due to internal components or tank shape variations.

Q4: What about metric measurements?
A: Convert cm to inches (1 inch = 2.54 cm) before using this calculator or use a metric-specific tool.

Q5: Does this account for tank thickness?
A: No, use internal dimensions for most accurate results. For very thick-walled tanks, subtract twice the wall thickness from each dimension.
