Pool Volume Formula:
From: | To: |
The pool volume formula calculates the total water capacity of a rectangular pool in gallons. It takes into account the pool's length, width, and average depth, then converts cubic feet to gallons using the conversion factor 7.48 (gallons per cubic foot).
The calculator uses the pool volume formula:
Where:
Explanation: The formula first calculates cubic feet (L × W × D) then converts to gallons by multiplying by 7.48.
Details: Knowing your pool's volume is essential for proper chemical treatment, pump sizing, heater sizing, and general maintenance. Incorrect volume measurements can lead to improper chemical balance.
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. All values must be in feet and greater than zero.
Q1: How do I measure average depth for a sloping pool?
A: Add the shallow end depth to the deep end depth, then divide by two. For example: (3ft + 8ft)/2 = 5.5ft average depth.
Q2: What if my pool isn't rectangular?
A: This calculator is for rectangular pools. Different formulas exist for circular, oval, or irregular shaped pools.
Q3: Why is 7.48 the conversion factor?
A: There are 7.48052 gallons in one cubic foot of water. We use 7.48 for simplicity in calculations.
Q4: How accurate is this calculation?
A: It provides a good estimate for standard rectangular pools. Actual volume may vary slightly due to pool shape variations, steps, or benches.
Q5: Can I use this for above-ground pools?
A: Yes, as long as the pool is rectangular in shape. The calculation works the same for in-ground and above-ground pools.
