Naming the amount.

Yo, Cannabis people, Happy Holidays.

Um, I don't want to sound like a idiot but I don't know the names for the amounts.
Ex. 20 is a dub
I don't know if it is different around the world,i guess it depends on the place and the quality...but anyways if you could help me out and not flame me too bad.

Thank you
