Cindy, a grain is actually 65 milligrams so it's quite large. I don't intend to measure powders to put into capsules and most of that is done by machines nowadays anyway. Mostly you have to know because some older doctors still write scripts in grains or less often, scruples. I intend to work in a hospital pharmacy and preferably in a cancer center pharmacy mixing chemotherapy bags.
