1. What is the Pool Volume Formula?

The pool volume formula calculates the total gallons of water in a rectangular pool by multiplying length × width × average depth × 7.48 (the number of gallons in a cubic foot of water).

2. How Does the Calculator Work?

The calculator uses the pool volume formula:

Where:

• \( V \) — Volume in gallons
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( D \) — Average depth in feet
• 7.48 — Gallons per cubic foot

Explanation: The formula calculates the cubic footage of the pool and converts it to gallons using the standard conversion factor.

3. Importance of Pool Volume Calculation

Details: Knowing your pool's volume is essential for proper chemical treatment, pump sizing, heating calculations, and general maintenance.

4. Using the Calculator

Tips: Measure your pool's length and width at their longest points. For depth, average the shallow and deep end measurements if your pool has a slope.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure average depth?
A: For pools with a slope, add the shallow end depth and deep end depth, then divide by 2.

Q2: What if my pool isn't rectangular?
A: This calculator is for rectangular pools. Different formulas exist for circular, oval, or kidney-shaped pools.

Q3: Why is 7.48 the conversion factor?
A: There are 7.48052 gallons in one cubic foot of water (standard conversion factor).

Q4: How accurate should my measurements be?
A: For best results, measure to within 1/4 foot (3 inches) for length/width and 1 inch for depth.

Q5: Does this work for above-ground pools?
A: Yes, the formula works for any rectangular pool, whether in-ground or above-ground.
