So.. yeah.. uhm Google it nub ? There must be thousands of convertors online ? Yeah.. there sure are.. trouble is the calculator that comes up right on Google's main page is showing it varies by the type of fluid / substance.. It's not water so I don't want to go with that conversion.. These will be the tips I plan to fill.. but the source for my oil/juice/liquid says they get theirs in grams since it's all for themselves & don't know what that would be in ml. Danke /salute
