wtf is a gm?.gram? no way a doctor says to take 4000mg of aspirin, niether would they say to take 4 mg

The (regular) 5 grain aspirin tablet is 325 milligrams.
This would represent 12 tablets per day.
This dose would normally be given as two tablets every four hours.
Or as on a prescription ASA gr. X Q4H.
