in my old pipe it was 3 per gram, so 3 x 3.5 = 10.5 so maybe 9 by the time you lose random weed flakes etc. but with my bubbler it would be like...3 bowls hehe it EASILY fits 2g's but i was able to pack 3.2 when i chopped up some kush and really cramed it in there...damn that bowl went around a 4 head rotation like 5 times lol
