I'd like to preface this by saying that I'm a former high school science and math teacher...
I like to measure my oils and NaOH in metric. So I thought to myself: "self, why don't you measure your molds in metric to get the mass of oils required that way, instead of mucking around converting ounces back to grams?"
So I went about my merry way, thinking of all the calculations I'll save myself. My 12" x 4" x 4" mold becomes a 30.48cm x 10.16cm x 10.16cm mold.
Are you laughing yet?
My mold, according to me, in metric, should require 1258.5__ of oil. I was a bit fuzzy on the units after multiplying the volume by 0.4. I decided it must be grams. I need 1258.5g of oil.
According to most normal people's calculations, using a factor of 0.4, my 12" x 4" x 4" mold needs 78.4oz of oils.
I make my recipe using 1258g of oil. I go to pour into the mold and my mold is only halfway full. I think to myself: "self, this doesn't seem right."
You can laugh now.
Turns out, 1258g does not equal 78.4oz. I was roughly 34oz short.
I now have little 2" high beer soaps.
(In all seriousness, this could have been quite bad if I'd measured the NaOH correctly and the oils incorrectly. But I input the oils into soapcalc, so my NaOH was correct for the amount of oils).
Lesson learned: the imperial system works?...?!...
