Yeah, I've never heard of a dime being an actual weight- in our state, and a few surrounding ones, it's always a 10 buck bag of weed.

I got 1/8 the other day of some phenominal headies, and when I weighed it, it was 4.6 grams I love it when they add a bit more...

For the headies, I get

Gram= 10
Half 1/8= 25-30
1/8= 60
1/4= 80
O= 250
