When purchasing cannabis, the 1/8 (one eighth) quantity is a very popular one. But how many grams are actually in 1/8 of an ounce of marijuana?
For all intents and purposes, an eighth of cannabis is 3.5 grams; this is the amount you’ll be purchasing when buy 1/8 from a dealer or cannabis outlet. However, technically speaking 1/8 of marijuana is 3.54 grams.
The same slight discrepancy is true of all other typical forms of marijuana quantities that are sold:
- 1/8 an ounce = 3.54 grams
- 1/4 an ounce = 7.08 grams
- 1/2 an ounce = 14.17 grams
- 1 ounce = 28.34 grams

When purchasing from a dealer or cannabis retail outlet, all of these will be quantities that are used; in addition to the standard one gram. Some will sell smaller amounts, such as half grams; others may sell larger amounts, such as quarter or half pounds (four and eight ounces). In rare instances a full pound might be offered; this equals a full 16 ounces. However, in most states with legal cannabis, outlets aren’t legally allowed to sale over an ounce (though in Maine the limit is 2.5 ounces).
