I have the KD7000 and when I make a batch of soap and it calls for something like 3.08 oz, I can never get it at 3.08. I can either get 3.05 or 3.10. I have been just going with 3.10 of whatever it is I am weighing, but got to thinking that maybe I don't need to do that with lye? I figure it is ok with water and oils. Is this amount anything to fret over? Should I try to start weighing in grams instead? I didn't really think it was an issue until I was reading another post and saw that since I make smaller batches (I've made 1.5 lbs, and 21 oz batch sizes) it might be a bigger deal than I thought. What do you think?
