We buy our weed in grams here, so when I read on international sites how much people smoke and what they pay for an ounce(oz) or an 1/8 a 1/4, a 1/2 etc. I'm always confused and have no clue what they're talking about and whether the prices are good or not. There are so many different ounces and pounds that I don't even know which ounce or pound to use if I want to convert to grams. (source wikipedia) International avoirdupois ounce 28.3495231 grams International troy ounce 31.1034768 grams Apothecaries' ounce 31.1034768 grams Maria Theresa ounce 28.0668 grams Dutch metric ounce 100 grams Chinese metric ounce 50 grams Pounds are even more confusing: Pound (mass) - Wikipedia, the free encyclopedia And what is an 1/8 or a 1/4, 1/2, etc? I often just read something like, "I bought an 1/8". Is it an 1/8 of an ounce or a pound? I'm so confused about that. :jointsmile: So, how to convert ounce, pound, 1/2, 1/4, 1/8 etc. to gram, which measuring units are used in the weed business? Thanks.
