1. What is the Pool Volume Formula?

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

2. How Does the Calculator Work?

The calculator uses the pool volume equation:

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 volume 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, heater sizing, and general maintenance.

4. Using the Calculator

Tips: Measure length and width at the pool's longest and widest 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 depth for a sloped pool?
A: Average the shallow end depth and deep end depth (shallow depth + deep depth) ÷ 2.

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

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

Q4: How accurate is this calculation?
A: It provides a good estimate for standard rectangular pools. Irregular shapes or features like steps may affect accuracy.

Q5: Can I use meters instead of feet?
A: For metric measurements, use length × width × depth × 1000 (liters per cubic meter) then convert to gallons if needed.
