To be exact, an eighth of an ounce is 3.54375 grams; however, the standard practice most medical marijuana dispensaries use is to round it to 3.5 grams. Some generous dispensaries and delivery services will give you an extra 0.5 grams, making an eighth 4.0 grams — although dispensaries that do this most likely make up the difference by increasing the cost of the eighth from the get-go.
