there was a day and time when I would have felt the same and I did convert home recipes to pro formulas. It has been a long time ago and I know longer have all the little things like fractions or whole teaspoons/tablespoons in my memory. The same is true with things like coconut and nuts. I just don't have the weights per volume in my head like I used to. All the books that have that info are packed away and very inaccessible. At the time of my post I was in abit of a time crunch and hoped someone might have a formula available. I also needed something a good bit larger than the single cake home recipe.
