Circular Pool Volume Formula:
From: | To: |
The circular pool volume formula calculates the water capacity in gallons for round swimming pools. It accounts for the pool's radius, average depth, and converts cubic feet to gallons.
The calculator uses the circular pool volume formula:
Where:
Explanation: The formula first calculates the area of the circular pool (πR²), then multiplies by depth to get cubic feet, and finally converts to gallons.
Details: Knowing your pool's volume is essential for proper chemical treatment, pump sizing, heating calculations, and general maintenance.
Tips: Measure the pool's radius (half of diameter) and average depth (shallow end + deep end ÷ 2). Enter values in feet for accurate results.
Q1: How do I measure average depth?
A: Measure shallow end depth and deep end depth, add them together, and divide by 2.
Q2: What if my pool isn't perfectly round?
A: For oval pools, use the average of the long and short radii. For irregular shapes, consider breaking it into circular sections.
Q3: Why multiply by 7.48?
A: There are 7.48 gallons in one cubic foot of water.
Q4: How accurate is this calculation?
A: Very accurate for perfectly round pools with uniform depth. Slight variations may occur with irregular shapes or varying depths.
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).
