So I think I am going crazy thinking about this issue. I need to fill 1000 units 0.25 fl. oz. of lip balm at 250mg of CBD each. In order to make sure each 'tin' gets 250mg, my formula needs 250 grams of CBD. How would an excel sheet keep my formula dose consistent if I need to change volume of units? Or is this the completely wrong way to think about this?
