Pool Volume Formula:
From: | To: |
The pool volume calculation determines the total water capacity of a swimming pool in gallons. This is essential for proper chemical treatment, pump sizing, and maintenance planning.
The calculator uses the standard pool volume formula:
Where:
Explanation: The formula calculates the cubic footage of the pool and converts it to gallons using the standard conversion factor.
Details: Knowing your pool's volume is crucial for proper chemical dosing, selecting the right size pump and filter, and calculating heating requirements.
Tips: Measure the length and width at their longest points. For depth, average the shallow and deep end depths if your pool has a slope. All measurements should be in feet.
Q1: How do I measure depth for a sloped pool?
A: Add the shallow end depth and deep end depth, then divide by two to get the average depth.
Q2: What about irregularly shaped pools?
A: For circular pools, use π × radius² × depth × 7.48. For complex shapes, divide into regular sections and calculate each separately.
Q3: Why is 7.48 the conversion factor?
A: There are 7.48052 gallons in one cubic foot of water, which we round to 7.48 for simplicity.
Q4: How accurate is this calculation?
A: It provides a good estimate. For precise chemical dosing, consider additional factors like steps, benches, and water features.
Q5: Does this work for saltwater pools?
A: Yes, the volume calculation is the same regardless of water type, though chemical treatment differs.
