Here's the interesting part:

1. Use the calculator for a cylinder dimension of: 1.5" radius and 23" height. NET RESULT IS: Total Batch Weight 1884.47 grams

That number is shy of the true amount by about 786 grams! Whoa Nellie! I kept looking at the number given me and in my mind I just knew that the 1884 number was off by quite a bit... actually by about 42% !! Time for the webmasters to "git 'er done" and correct this anomaly.

2. Correct way to compute is: Radius of 3" cylinder is 1.5", this number needs to be squared: 1.5 x 1.5= 2.25

Since the classic formula is Pi x r/2 for area, for a cylinder it is: V=πr2h Volume = pi x r/2 x h (height)

So the 3" x 23" cylinder's volume works out to: 1.5 x 1.5 = 2.25 x pi (3.14) = 7.07 sq. inches x 23" height = 162.61 cubic inches.

(Now we go to Google to convert cu. inches to cubic centimeters (equivalent... more or less to grams of oil).

We'll round this off to 163 cu. inches for simplicity's sake.

163 cu. inches converted to cubic centimeters is: 2671.09 cu. cm. this is "roughly" equivalent to the amount of oils, etc. used to fill the cylinder with soap mixture.

Actually my recipes are set to 2670 grams on the "By Total Size" adjustment and they completely fill up the PVC pipe which is actually 23-3/4" in height with a 1/2 thick thick internal plug for the bottom of the mold.

Thoughts? Suggestions? Comments? I know there will be some MENSA scholar or M.I.T. grad out there who will take me to task on my above though processes, but hey it's not the first time I've been around the "proverbial block". At my age, Rhino Hide Skin is a blessing. I'm no Einstein that's for sure!

So... I wanted to point this out in the hope of getting that part of the calculator recipe resizer tweaked and corrected. I'm someone resized a batch and was a little baffled about the net result.
