Question: is 2 dubs an 8th?
Answer: An ounce is a little over 28 grams, but for rounding purposes, the industry standard is 28 grams per ounce. An ounce is broken up into 8 equal increments of 3.5 grams, hence the 'eighth. ... A forty sack will be two dubs put together, so you can see how it differs from an eighth, which is always 3.5 grams.
