What does cannabis look like? A visual guide to cannabis quantities

A gram, an eighth, an ounce–what does it all mean? We’ve all been there at one point. Attempting to make sense of the names associated with different cannabis quantities can be challenging. Central to the confusion is conceptualization of weight, which depends on both product size and density.

If you are new to cannabis, we hope this video and visual guide will provide you with a general framework to wrap your head around the common sale quantities for flower. Keep in mind that these depictions are approximations, given that density varies (at times drastically) between products. In other words, a dense cannabis flower can look a lot smaller than a fluffy bud and still carry the same weight.

Thankfully, cannabis shops and producers use digital scales to determine the exact weight of your weed before it is packaged. And, if you wish to weigh the weed from your own garden or verify your purchased products, digital scales can easily be found for purchase. Remember that moisture is part of the weight. Cannabis flower will lose weight as it ages and dries out.

### How to convert ounces of weed to grams

For reference, here is a quick conversion guide from ounces of weed into grams.

• Eighth (1/8) ounce = 3.5 grams
• Quarter (1/4) ounce = 7 grams
• Half (1/2) ounce = 14 grams
• Full (1) ounce = 28 grams

The price of flower varies depending on the quality of the product and the market in which it is sold. You can expect to pay between \$4 and \$20 for a gram of flower—sometimes getting a price break when you purchase larger quantities.

### Express Summary: Ounces vs grams of weed

Cannabis quantities can be confusing. How much is a gram of weed? How big is an ounce? And an eighth is an eighth of what, exactly? Let’s zoom out. Cannabis flower is often sold in quantities, ranging from one gram to one ounce. Some common terms you hear are an eighth, which means an eighth of an ounce (or three and a half grams), a quarter ounce (or seven grams), and a half ounce, (14 grams).

The smallest amount of cannabis flour you can typically buy is one gram. A gram is going to roll about two joints or three to four bowls, making it a great option for the occasional consumer or when trying a new strain. Next size up is three and a half grams, or an eighth. That’s enough for about seven joints, seven grams or quarter ounce will get you about 14 joints, which means that 14 grams (or a half ounce) can roll nearly 30 joints. So, a full ounce of cannabis, which is 28 grams, can roll nearly 60 joints or pack upwards of 100 bowls. It’s worth noting that pre-rolled joints are often sold in half gram or full gram quantities. You may choose a half gram to share with a friend or a full gram for a larger group.

The last thing to know is about density of your cannabis flower, as it varies greatly by strain. So an eighth of dense gelato buds might look full and dense, while an eighth of Maui Wowie buds look light and fluffy.
