Pool Volume Formula:
From: | To: |
Pool water volume refers to the total amount of water contained in a swimming pool, measured in gallons. Knowing your pool's volume is essential for proper chemical treatment, filtration, and maintenance.
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: Accurate volume measurement is crucial for proper chemical dosing, pump sizing, filter maintenance, and heating efficiency. Incorrect volume can lead to water quality issues or equipment problems.
Tips: Measure your pool's length and width at their longest points. For depth, average the shallow and deep end measurements if your pool has a slope. Enter all dimensions in feet.
Q1: How accurate is this calculation?
A: Very accurate for rectangular pools. For irregular shapes, use multiple rectangular sections or consult a pool professional.
Q2: What about circular or oval pools?
A: For circular pools, use π × radius² × depth × 7.48. For oval pools, use π × ½ length × ½ width × depth × 7.48.
Q3: Why is pool volume measured in gallons?
A: Most pool chemicals are dosed per gallon, and pool equipment (pumps, heaters) is rated in gallons per minute/hour.
Q4: How often should I recalculate my pool volume?
A: Only if you significantly change the pool's shape or size. Seasonal water level changes don't require recalculation.
Q5: What if my pool has an irregular shape?
A: Break it down into regular shapes (rectangles, circles) and calculate each section separately, then sum the volumes.
