How was the .4 calculated?
I apologize in advance for my poor search abilities.
Background:
For several months, I have used the basic formula (H * W * L) * .4 to convert the volume of my mold into the amount of oil to put into a lye calculator.
This method has worked just fine for me.
However, it bothers me that I can't figure out how the .4 was calculated.
I read the stickied thread about calculating oil using the .4 rule of thumb, and it was suggested that the .4 was related to the amount of water that is being mixed with the lye. That sounds reasonable, but to date, I just can't seem to recreate that math.
I have been able to accurately calculate the weight of a oil in grams that will fill a particular mold using the density of the oil to convert from volume to fluid ounces, and then to ounces, and then to grams.
But reverse engineering the .4 is just baffling me.
Does anyone have a link or explanation or just the full formula for how the .4 was derived?
Thanks in advance,
- Paul
