1. What is a Tank Dimensions to Gallons Calculator?

Definition: This calculator converts tank dimensions (in inches) to volume in gallons for both rectangular and cylindrical tanks.

Purpose: It helps determine the liquid capacity of tanks used in industrial, agricultural, or residential applications.

2. How Does the Calculator Work?

The calculator uses different formulas based on tank shape:

Where:

• \( V_{gal} \) — Volume in gallons
• \( L, W, H \) — Length, Width, Height in inches (rectangular)
• \( r, h \) — Radius and height in inches (cylindrical)
• 231 — Conversion factor (cubic inches per gallon)

Explanation: The calculator first computes volume in cubic inches, then converts to gallons by dividing by 231.

3. Importance of Tank Volume Calculation

Details: Accurate volume calculations ensure proper sizing for storage needs, chemical dosing, and system design.

4. Using the Calculator

Tips:

• Select tank shape (rectangular or cylindrical)
• Enter dimensions in inches
• For cylindrical tanks, measure radius (half of diameter)
• All values must be > 0

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use feet instead of inches?
A: No, this calculator requires inches. Convert feet to inches by multiplying by 12.

Q3: What about oval or irregular tanks?
A: For oval tanks, use average dimensions. For complex shapes, consult specialized calculators.

Q4: Does this account for tank thickness?
A: No, it calculates internal volume based on given dimensions. Subtract wall thickness if needed.

Q5: How accurate is this calculation?
A: It's mathematically precise for perfect geometric shapes. Real-world tanks may vary slightly.
