How to
determine pool or spa water volumes or measure the interior
surface area? The volume of a pool, spa or hot tub is
important in helping to determine the quantities
of chemicals to be added or to properly size
some accessory equipment. While a precise figure
is always best, for most applications a
reasonably close approximation will suffice. In
the long term, the amount of chemicals required
depends on bather usage, location, exposure and
maintenance practices, as well as the actual
water volume. Interior pool or spa surface area
is important to determine the cost of a
resurfacing job or the amount of paint required
for a refinishing. If problems arise,
refer to the Pool Problems
Page or Spa Problems
Page, as a source of problem-solving information, broken
down into various categories. Scroll down the page and
click on the linked
keywords or
catch phrases below,
to access additional information, on that topic or product.

Irregularly Shaped Pools or Spas |

|
|
If possible check with the builder or dealer.
You may have to calculate the volume based on
two separate areas, if the pool is an "L" or "T"
shape.
For a hexagon or Octagon shape, calculate as a
circular pool or spa.
Otherwise, use the calculations for either an
oval or rectangular pools or spas and substitute
an average diameter, width or length. |

Calculating Pool or Spa Interior Surface Area |
| |
The calculations below are approximations only
and are based on average shallow and deep end
sizes and depths.
Pools or spas with atypical measurements may
require different amounts. |
|
| |
American/English Units: square feet
All
measurements are in feet. |
|
|
●
Rectangular or Freeform Shapes: L X W X 1.6
= Square Feet of Interior Surface
●
Oval or
Lazy L Shapes: L X W X 1.65 = Square Feet of
Interior Surface
●
Roman
Style Shapes: L X W X 1.55 = Square Feet of
Interior Surface |
| |
Metric Units: square meters
All
measurements are in meters. |
|
|
●
Rectangular or
Freeform Shapes: L X W X 1.6 = Square Meters
of Interior Surface
●
Oval or Lazy L
Shapes: L X W X 1.65 = Square Meters of
Interior Surface
●
Roman Style
Shapes: L X W X 1.55 = Square Meters of
Interior Surface |

You've seen the
formulas for conversion. But you don't always
have a pad and paper handy: let alone a
calculator. Here's an easy way to convert these
values.
From ºC to ºF: double the ºC, subtract 10%, add
32 and now you have ºF. Example: 30ºC times 2 =
60, minus 10% (-6) = 54, add 32 and you get
86ºF.
From ºF to ºC: subtract 32, divide in half, add
10% and now you have ºC. Example: 90ºF minus 32
= 58, divide in half = 29, add 10% (2.9) and you
get 31.9ºC. |
