Grams, ounces, “eights” and “quarters” are just some of the terms that can be extremely confusing for both beginner and intermediate cannabis users.
This guide will break down imperial and metric weed measurements so that they are easy to understand.
Eighth of weed
You can often hear people say “an eighth”, or “a half quarter” and wonder how much weed that is exactly.
An eighth of weed refers to an eighth of an ounce. This is the amount of weed most frequently purchased by people who use cannabis moderately.
Converted to metric system, an eighth of an ounce is just a little over 3.5 grams.
An eighth of weed is about the size of a walnut. Depending on your appetite, you can roll up to 3 blunts, 3 to 4 large joints, or approximately 7 half-gram joints.
Fun fact: An eighth of weed is often dubbed a “slice”, or a “cut”. This is because pizzas are usually divided into 8 slices.
Half-eighth of weed
The name says it all: It’s one half of the eight of an ounce.
Although it’s half-eights are rarely sold on the market, it’s worth mentioning this term because you can still hear it from time to time.
Half-eighth of weed is around 1.7-1.8 grams, enough for several medium joints.
Quarter of weed
Slang names like “Q”, “quad” or just a “quarter” refer to a quarter of an ounce.
That’s 7.0874 grams, but it’s usually rounded to precisely 7 grams.
Intermediate users generally like to buy a “quarter” which can last for days, or even weeks depending on one’s frequency of use.
With a quarter of weed you can roll about six or seven blunts, or a handful of joints.
A quarter of weed is about the size of an apple.
Half of weed
Following the same logic, a half of weed refers to a half of ounce of weed.
A half is 14.1747 grams of dried cannabis, but of course, it’s rounded to 14 grams.
With this amount the price really starts to break, although it will also depend on the quality of the buds in question.
A half of weed is about the size of an orange. If you want to make some edibles, this is the amount usually required in recipes for making cannabutter, which is at the core of all canna-edibles.
Regular users like to buy a half of an ounce so they don’t have to go every now and then to refill their stash.
A half of weed is perfect for parties, road trips and other activities of that nature.
Ounce of weed
An ounce of weed is exactly that—a full ounce. That’s precisely 28.3495 grams, and it’s usually sold as 28 grams.
You can often hear stoners abbreviate an ounce to just an “O”. An ounce is also referred to as a “zip”.
Now this is a pretty large amount of weed, and very few places actually sell in this quantity.
South of the border, most dispensaries in the US (where cannabis is legal for recreational use) offer ounce deals.
Buying weed in whole ounces is the most cost-effective way to buy weed for daily, high-volume users.
What does an ounce of weed look like? It’s about the size of a coconut.
Quarter-pound of weed
In the cannabis community it’s known as a “QP”, and the name says it all.
A quarter-pound of weed equals 113.4 grams, or 4 ounces.
Half-pound of weed
“Half-pack” and “half-pounder” are the main slang terms for a half-pound of weed.
A half-pound totals to 226.8 grams, or 8 ounces of dried cannabis.
Pound of weed
One pound (1 lbs) is 448 grams, or sixteen ounces. And that’s quite a lot— imagine a bulk of weed the size of a watermelon and you’re almost there.
To be honest with you, I don’t think one person (or an entire group of people) could consume that much weed in any reasonable amount of time, so I’d consider this a dispensary-level volume of cannabis.
Keep in mind that the legal limit for possession and sharing in Canada is 30 grams.
One gram of weed
If you’re looking to buy small quantities of weed, it’s best to go for a gram, especially if you haven’t tried that strain before.
A gram of weed is often called a “dime bag” on the street. Also, it’s the smallest amount of weed you can purchase.
What does a gram of weed look like?
It’s about the size of a hazelnut. Experienced users who have developed tolerance to THC usually put an entire gram in one joint.
If you are smoking alone you can split it in half and roll two smaller joints.
If you’re new to cannabis this will undoubtedly be too much for you, especially if it’s a high-THC indica.
Five grams of weed
Most of the Canadian LP’s sell their products in five-gram and ten-gram packages.
Five grams of weed is 0.1763 ounces. This amount of weed looks about the size of an egg, and it’s a perfect amount for a few weeks of self-medication.
Five grams would be enough for 4 to 5 blunts, or five to ten joints, depending on their size.
In some dispensaries you can also sometimes hear the term a “5-gram eighth”. As we mentioned before an eighth is 3.5 grams, so what does it have to do with 5 grams?
This term refers to the price—a customer who buys a five-gram eighth will get 5 grams for the price of an eight (3.5g), which is a pretty sweet deal if you ask me.
10 grams of weed
Depending on the medical condition, most patients would buy a 10-gram jar and consume it over the course of weeks.
Ten grams is more than enough for rolling a bunch of joints for you and your friends, but it’s probably a bit too much for any crew to consume in one sitting.
A kilogram of weed
One kilo of weed is such a huge amount that I’ve only seen it in just one (of the numerous coffeeshops) I visited in Amsterdam.
One kilogram equals a thousand grams, or 2.2046 pounds.
Grams to ounces / ounces to grams
All these differing terms and measurement systems can be really confusing, but it’s actually quite simple to do the math.
Here’s a formula to help you figure out how many grams there are in an ounce.
One gram is 0.0352 ounces, so whatever number of grams you want to convert into ounces just multiply it by that number.
One ounce equals 28 grams, therefore by multiplying your ounces with 28, you’ll get the exact quantity in grams.
