Marijuana is sold in grams and ounces in herbal dispensaries and stores, and depending on the laws of each state in the United States, carrying different weights of marijuana can face other legal issues.
As a consumer, you should be aware of the amount of marijuana that is legal to consume and understand how these weight units translate to protect yourself better.

What is a gram, and how much is it?

A gram, sometimes colloquially referred to as a dime bag or dubbing, is the smallest size of a dried flower.

What is a pound?

You already know that a pound (abbreviated lb) is a unit of weight equal to 16 ounces.
If you live in the United States, you probably have a rough idea of your weight and an ambivalent sense of the metric system used in other parts of the world.

One eighth = eight ounces = 3.5 grams
1 quarter = quarter ounce = 7 grams
1 half = half ounce = 14 grams
1 ounce = 28 grams
One pound = 453 grams (a pound of anything is 453.592). Many think that 16 ounces or a pound contain 448 grams; this 448 gram is wrong.
