1. What is a Rectangle Tank Volume Calculator?

Definition: This calculator estimates the volume of a rectangular tank in gallons based on its dimensions in inches.

Purpose: It helps professionals and DIYers determine the capacity of rectangular tanks, aquariums, or containers.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{gal} = \frac{L \times W \times H}{231} \]

Where:

\( V_{gal} \) — Volume in gallons
\( L \) — Length in inches
\( W \) — Width in inches
\( H \) — Height in inches
231 — Cubic inches per gallon (conversion factor)

Explanation: The calculator multiplies the three dimensions to get cubic inches, then converts to gallons.

3. Importance of Tank Volume Calculation

Details: Accurate volume calculation ensures proper sizing for liquid storage, chemical dosing, and system design.

4. Using the Calculator

Tips: Measure the inside dimensions of your tank in inches. 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: Does this work for irregular shapes?
A: No, this only works for perfect rectangular tanks. Use different calculators for cylindrical or irregular shapes.

Q3: Should I use inside or outside dimensions?
A: Always use inside dimensions for accurate volume calculations.

Q4: How do I convert to liters?
A: Multiply gallons by 3.78541 to get liters.

Q5: Does this account for tank thickness?
A: No, subtract twice the wall thickness from each dimension for precise calculations.
