1. What is Volume of Rectangle in Gallons?

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

Purpose: It helps determine liquid capacity of rectangular containers, tanks, or spaces for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

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 product of the three dimensions gives cubic inches, which is then converted to gallons.

3. Importance of Volume Calculation

Details: Accurate volume calculations are essential for liquid storage, aquarium sizing, chemical mixing, and industrial applications.

4. Using the Calculator

Tips: Enter all dimensions in inches. The calculator will provide the volume in US gallons. All values must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use feet instead of inches?
A: No, this calculator requires inches. For feet, multiply each dimension by 12 first.

Q3: Is this for US or UK gallons?
A: This calculates US gallons (231 cu in). UK gallons are 277.42 cubic inches.

Q4: Does this account for container thickness?
A: No, this calculates internal volume. For external dimensions, subtract wall thicknesses.

Q5: How precise is this calculation?
A: Very precise for perfect rectangles. Irregular shapes require different methods.
