Circular Pool Volume Formula:
From: | To: |
The circular pool volume formula calculates the total water volume in a cylindrical pool. It accounts for the pool's radius, average depth, and converts cubic feet to gallons.
The calculator uses the formula:
Where:
Explanation: The formula calculates the cylindrical volume in cubic feet and converts it to gallons (1 cubic foot = 7.48 gallons).
Details: Knowing your pool's volume is essential for proper chemical treatment, pump sizing, and maintenance planning.
Tips: Measure the pool's radius (half of diameter) and average depth (shallow end + deep end divided by 2). Enter values in feet.
Q1: What if my pool isn't perfectly circular?
A: This calculation works best for true circular pools. For oval pools, use the average of length and width as diameter.
Q2: How do I measure average depth?
A: Measure shallow end and deep end, then calculate (shallow + deep)/2. For multiple depths, take several measurements.
Q3: Why multiply by 7.48?
A: This converts cubic feet to gallons, as there are 7.48 gallons in one cubic foot of water.
Q4: What about pools with sloping bottoms?
A: The calculation assumes uniform depth. For more accuracy with slopes, divide pool into sections and calculate separately.
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).
