This is for you "Techie" types who have a boiling pot
or box with no markings on it that tell you how much water it holds.
Smaller pots usually have the quart capacity stamped on them. We're
working with cubic inches here. A cubic inch is a square that is
1" X 1" X 1" in size. Here is how to calculate
the round pot. Equation: Pi (3.14)
times the radius (diameter divided by
2) squared (times itself), times the
depth of the pot in inches divided by 231
(231 cubic inches in a gallon of fluid (which includes water)). Example: I
have a pot that is 18" in diameter (measure across the top side
to side) and 16" deep. These are rough measurements to the
inch. Pi = 3.14
The radius is 9" (18" divided
by two)
The radius squared is 9" X 9"
which equals 81.
So now we have 3.14
X 81 X 16
= 4,069 (this is the total cubic inches in the pot) 4,069 /
231 = 17.6 (the number of gallons the
pot will hold) Now, what about a box? Simple,
forget Pi. Width X Length X Depth (all in inches) / 231.
Why would you want to know this seemingly useless information?
Suppose you are going to borrow a big boiler set and want to use
my Boiled
Crawfish (or Crab) recipe. First thing you want to be able to at
least estimate is how much water you're dealing with right?
Now you have the way to do it!
