Thank you! I already knew how many oz the mold holds, but I couldn't remember if the total batch weight (I use Soapee) was what I was looking for. Yay!
I deal with math via my day job, so I like to keep things fairly simple when it comes to making soap.
To find out how much a mold will hold if I don't have that information I put it on the scale, tare it, fill it with water and them multiply it by 0.92 since oils/butters are lighter than water. It's an approximation, but it gives me a place to start for my first batch.
To start with a number to figure out how much Oils I will need for a mold, it starts with knowing your recipe. My recipe under the parameters I gave is 67.5% Oils...so I multiply that number by the total weight of the mold to: 0.675 x 44 = 29.70 and put that in as my Oil Weight and then I calculate and get 43.99 for my batch weight. Because I know that I can't scape every little bit of batter out of my bowl, or off my stick blender, or off my spatula...I rather be a little bit over than under which is why I went to 29.75 which is 44.07 or I could have just gone with 30.0 for 44.44.
