1. What is the Pool Capacity Formula?

The pool capacity formula calculates the volume of water a rectangular swimming pool can hold in gallons. It multiplies the length, width, and height (depth) of the pool in feet, then converts cubic feet to gallons using the conversion factor 7.48 (gallons per cubic foot).

2. How Does the Calculator Work?

The calculator uses the pool capacity formula:

Where:

• \( V \) — Volume in gallons
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( H \) — Height (depth) in feet
• 7.48 — Conversion factor (gallons per cubic foot)

Explanation: The formula first calculates the cubic footage of the pool, then converts it to gallons since pool capacity is typically measured in gallons.

3. Importance of Pool Capacity Calculation

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

4. Using the Calculator

Tips: Measure your pool's length, width, and average depth in feet. For irregular shapes, divide into rectangular sections and calculate each separately.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure average depth?
A: For pools with sloping bottoms, measure the shallow end depth and deep end depth, add them together, and divide by 2.

Q2: What if my pool isn't rectangular?
A: Different formulas exist for circular or oval pools. For complex shapes, consult a pool professional.

Q3: Why 7.48 gallons per cubic foot?
A: This is the standard conversion factor as one cubic foot equals 7.48052 US gallons.

Q4: How accurate is this calculation?
A: It's accurate for perfect rectangular pools. Real-world factors like curves, steps, and fittings may slightly affect actual capacity.

Q5: Can I use meters instead of feet?
A: Yes, but you'll need to use a different conversion factor (1 cubic meter = 264.172 gallons).
