1. What is Volume in Gallons of a Rectangle?

Definition: This calculator estimates the liquid volume a rectangular container can hold, measured in gallons.

Purpose: It helps determine capacity for tanks, aquariums, containers, or any rectangular space that holds liquids.

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

Explanation: The formula calculates cubic inches (L×W×H) then converts to gallons (1 gallon = 231 cubic inches).

3. Importance of Volume Calculation

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

4. Using the Calculator

Tips: Measure inner dimensions in inches for accurate results. 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: Convert feet to inches first (1 foot = 12 inches) or modify the formula to divide by 0.13368 instead.

Q3: Does this work for irregular shapes?
A: No, this is only for perfect rectangles. Use different formulas for cylinders or irregular shapes.

Q4: How accurate is this calculation?
A: It's mathematically precise for perfect rectangles. Real-world factors like container thickness may affect actual capacity.

Q5: What about UK gallons?
A: UK gallons are different (1 UK gallon = 277.42 cubic inches). Use a different conversion factor for UK measurements.
