Pool Tank Capacity Formula:
| From: | To: |
The pool tank capacity formula calculates the volume of water a rectangular pool can hold in gallons. It multiplies the length, width, and height (depth) of the pool in feet, then converts cubic feet to gallons using the conversion factor 7.48 gallons per cubic foot.
The calculator uses the pool capacity formula:
Where:
Explanation: The formula first calculates the cubic volume of the pool in cubic feet, then converts it to gallons since pool capacity is typically measured in gallons.
Details: Knowing your pool's capacity is essential for proper chemical treatment, pump sizing, filtration system maintenance, and heating calculations.
Tips: Measure your pool's length, width, and average depth in feet. For irregular shapes, divide into rectangular sections and calculate each separately. All values must be positive numbers.
Q1: How accurate is this calculation for non-rectangular pools?
A: For circular pools, use π × radius² × depth × 7.48. For irregular shapes, break down into regular shapes and sum the volumes.
Q2: Should I use average depth or maximum depth?
A: Use average depth for best results. Measure shallow end and deep end depths, add them, and divide by 2.
Q3: What if my pool has a sloping bottom?
A: For pools with gradual slopes, use the average depth. For pools with sudden depth changes, calculate each section separately.
Q4: Why is the conversion factor 7.48?
A: There are 7.48052 gallons in one cubic foot. The calculator uses the rounded value of 7.48 for simplicity.
Q5: How can I measure my pool dimensions accurately?
A: Use a measuring tape for above-ground pools. For in-ground pools, consult construction plans or use a long measuring tape with help.
