Swimming Pool Volumes

Calculate Water Volumen for Any Pool Shape

Calculate Your Pool

Knowing tu pool's water volume es esencial for proper chemical treatment, heating costs, water bills, y maintenance planning. Whether tu have un/una small backyard pool o manage un/una Olympic facility, preciso volume calculos ensure safe, efficient operation.

Standard Pool Volumes

Pool TypeTypical DimensionsUS GallonsLiters
Small backyard12' × 24' × 4' avg8,600 gal32,500 L
Medium residential16' × 32' × 5' avg19,200 gal72,700 L
Large residential20' × 40' × 5.5' avg33,000 gal125,000 L
25-metro lap pool25m × 10m × 1.5m99,000 gal375,000 L
Olympic pool50m × 25m × 2m660,000 gal2,500,000 L

Calculating Pool Volumen

Rectangular Pools (Constant Depth)

Formula: Longitud × Width × Depth × 7.48 = Gallons

Ejemplo: 30' × 15' × 5' deep
30 × 15 × 5 × 7.48 = 16,830 galones (63,700 L)

Rectangular Pools (Variable Depth)

Use average depth: (Shallow end + Deep end) ÷ 2

Formula: Longitud × Width × Average Depth × 7.48 = Gallons

Ejemplo: 40' × 20' pool, 3' shallow un/una 8' deep
Average depth: (3 + 8) ÷ 2 = 5.5'
40 × 20 × 5.5 × 7.48 = 32,912 galones (124,600 L)

Circular Pool Calculation

Formula: Radius² × π × Depth × 7.48 = Gallons

Or simplified: Diameter² × 0.785 × Depth × 7.48 = Gallons

Ejemplo: 18' diameter pool, 4' deep
18² × 0.785 × 4 × 7.48 = 7,619 galones (28,840 L)

15' × 48"5,31020,100
18' × 48"7,65028,960
21' × 52"11,50043,530
24' × 52"15,00056,780
27' × 52"19,00071,920

Oval Pool Calculation

Formula: Longitud × Width × 0.785 × Average Depth × 7.48 = Gallons

Ejemplo: 15' × 30' oval, 4' deep
15 × 30 × 0.785 × 4 × 7.48 = 10,568 galones (40,000 L)

Irregular y Freeform Pools

For kidney-shaped, L-shaped, o otro irregular pools:

  1. Divide el/la pool into simpler shapes (rectangles, circles)
  2. Calculate cada section separately
  3. Suma el/la volumes together

L-Shaped Pool Ejemplo

Main section: 20' × 15' × 5' = 11,220 gal
Extension: 10' × 8' × 4' = 2,394 gal
Total: 13,614 galones (51,540 L)

Aplicaciones practicas

Chemical Dosing

Most pool chemicals son dosed per 10,000 galones. Knowing tu exacto volume prevents over- o under-treatment:

  • Chlorine: 1-3 ppm (parts per million)
  • pH adjusters: Vary by product
  • Algaecide: Typically per 10,000 galones

Heating Costs

It takes aproximadamente 8.33 BTUs un/una raise 1 galon of water 1°F. Un/Una 20,000-galon pool heated desde 70°F un/una 80°F requiere:

20,000 × 8.33 × 10 = 1,666,000 BTUs

Water Costs

Water rates son often per 1,000 galones. Filling un/una 25,000-galon pool at $5/1,000 galones = $125 in water alone.
