How Many Grams in 1/8 of Marijuana?


An eighth of cannabis.

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

Below is a visual comparison of these quantities, courtesy of Leafly:


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).

Other marijuana quantities:

Although the quantities shown in the image above are the most common when it comes to marijuana, some like to purchase even larger amounts. Here are some of those options:

Quarter pound:

A quarter pound of marijuana contains four ounces. Given that most legal states have a limit of 2.5 ounces of less, purchasing a quarter pound or more at one time is typically relegated to the black market. A quarter pound equals:

  • 32 eights
  • 112 grams

Half pound:

A half pound of marijuana contains eight ounces. A half pound equals:

  • 64 eights
  • 224 grams

Full pound:

A full pound of marijuana contains 16 ounces. A full pound equals:

    • 128 eights
    • 448 grams

    Back in my underground gardening days, I had an old balance scale but without a half gram weight. So, I decided to make 32 gr. OZ’s Makes the division simpler, I could use my scale without guessing and it made a lot of my friends more than satisfied with their commerce. Besides, in my world, it’s about the product, not the profit.
