1. What is Pool Volume Calculation?

Pool volume calculation determines the total water capacity of a swimming pool in litres. Knowing your pool's volume is essential for proper chemical treatment, filtration, and maintenance.

2. How Does the Calculator Work?

The calculator uses the rectangular pool volume formula:

Where:

• \( V \) — Volume in litres
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( D \) — Average depth in feet
• 28.32 — Conversion factor (cubic feet to litres)

Explanation: The formula calculates cubic volume then converts from cubic feet to litres (1 cubic foot = 28.32 litres).

3. Importance of Accurate Pool Volume

Details: Proper chemical dosing depends on accurate volume. Under-dosing leads to ineffective treatment, while overdosing can damage equipment and irritate swimmers.

4. Using the Calculator

Tips: Measure length and width at the longest/widest points. For depth, average shallow and deep end measurements if your pool has varying depth.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure an irregularly shaped pool?
A: For circular pools, use π × radius² × depth × 28.32. For oval pools, use π × ½ length × ½ width × depth × 28.32.

Q2: What if my pool has varying depths?
A: Calculate average depth: (shallow end depth + deep end depth) ÷ 2.

Q3: Why is pool volume important?
A: Essential for proper chemical balancing, pump/filter sizing, heater sizing, and water replacement calculations.

Q4: How accurate is this calculation?
A: Within 5-10% for rectangular pools. More complex shapes require more precise measurements or professional assessment.

Q5: Can I use meters instead of feet?
A: Yes, but use different conversion: L × W × D × 1000 (for cubic meters to litres). 1 cubic meter = 1000 litres.
