If you’re not familiar with how cannabis is weighed, measured, and sold, all of those terms can feel like a huge question mark. It’s clear they’re units of measurement for weed — but what exactly do they all mean?
A Breakdown of Weed Measurements
Let’s start with the smallest unit of measurement and work our way up.
A gram is defined as “metric unit of mass equal to one-thousandth of a kilogram.” A gram is a small unit of measurement, which makes it a solid choice for cannabis consumers who don’t want to purchase weed in small amounts. For example, if they’re looking to try a new strain or don’t consume cannabis frequently.
The rest of the units of measurement for cannabis have to do with ounces — either in full or a fraction.
An eighth is an eighth of an ounce — or 3 1/2 grams of weed. The eighth is one of the most popular, if not the most popular, weight to sell cannabis. For many people, an eighth of weed is the perfect amount; it’s enough to feel like you have plenty of weed at your disposal, but not so much that you feel like you have too much weed and not enough time to consume it.
The next unit of measurement is a quarter. A quarter refers to a quarter of an ounce, and it weighs approximately 7 grams. Technically, a quarter weighs 7.0874 grams, but the industry standard is to round down to the nearest gram.
A half is a half-ounce of weed, which weighs 14 grams.
And a full ounce? An ounce weighs 28 grams.
When you’re purchasing weed in a dispensary, typically, the highest volume you can buy at any one time caps out at an ounce. But people who work within the cannabis industry, such as buyers and dispensary owners, can buy in larger quantities — including pounds and kilograms. One pound is made up of 16 ounces — which weighs in at a truly impressive 448 grams.
Here’s a quick reference chart of how weed is measured — and how much each measurement weighs in grams:
1 eighth = ⅛-ounce = 3.5 grams
1 quarter = ¼-ounce = 7 grams
1 half = ½-ounce = 14 grams
1 ounce = 28 grams
1 pound = 16 ounces = 448 grams
How to Make Sure You’re Getting What You Pay For
When you purchase weed at the dispensary — whether you’re getting a single gram to test out a new grower or investing in a full ounce of your go-to strain — you want to make sure you’re getting what you paid for. And the only way to know for sure that your cannabis is the proper weight is to weigh it.
Your budtender should weigh out your cannabis in clear view; this way, you can see exactly how many grams are being weighed out — and how that corresponds to how much you asked for. If you get to the dispensary and can’t remember the gram conversions, just ask your budtender; he or she will be able to tell you how many grams are in an eighth, quarter, half, or ounce — and then can weigh out your weed to show you that the cannabis you’re taking home is the accurate weight.
In some states with adult-use cannabis laws, flower is required to come pre-packaged and was measured prior to arriving to the dispensary. If you still want to ensure that its the weight indicated on the packaged, you can weigh the flower with a scale at home.
