I really want to download and try out this spreadsheet. **** my laptop for committing suicide. I really need to get a new one.
I use metric measurements and everyone seems to agree on something around volume x .7 to calculate the amount of oils needed for a mold. So I tried using that twice now and end up with less soap than needed both times.I am completely ignorant when it comes to ounces and inches, so I did the math to figure out what it would be in cm and grams.
Take the volume in cubic cm (Length x Width x Height).
Divide that by 2,54^3 (which is 2,54 x 2,54 x 2,54) = 16,39 (to get the cubic cm into cubic inches).
And multiply by 28,35 to convert that into ounces.
Then multiply by the 0,4.
(L x W x H) / 16,39 x 28,35 x 0,4
Which is the same as :
(L x W x H) x 0,692
That's for the metric users.
Please note: I have not tested this formula so use at your own risk! Althouth the link given by TopCat http://www.smellychicksonline.com/2008/ ... your-mold/ gives 0,657 for metric users... I don't know where it comes from but it is very close to what I found.
Post #187 has the weight/volume ratios for water, oils, and solid fats given in both metric and imperial. It's kind of clunky to get there, but with that info, plus the measurements of your mold you should be able to come up with a fairly close answer.Has anyone worked this out in metric?
Sorry I am new and just using the search feature. I am not sure what Necro posting is.Post #187 has the weight/volume ratios for water, oils, and solid fats given in both metric and imperial.

Also, this is an old thread. Last post before ours were over two years ago (though I'll admit the info in the thread may well be handy to several of us new folks). Necro posting is kind of frowned on, overall. Much better to quote snips from the old thread you're referencing in a new thread.
I've done that with my silicone molds but this is a homemade wooden mold. It's not going to hold water.I know this may sound dumb but I hate math so all I do is fill my mold with water and then measure that to get my volume. Then I reverse engineer the water amount on a soap calc and oila! It isn't very scientific but it works every time.
