Basic weed measurements
Cannabis measurements are typically given in grams and ounces (even in the United States, where we love our imperial system).
Knowing how to convert between these units will keep you from getting shorted at the dispensary—or walking away with way more than you bargained for.
Here’s a breakdown:
1 Gram
A gram is enough to roll a joint or two or pack a few bowls.
Think of it as a sample size, perfect for testing a new strain.
You can expect to pay $10–$20 for a gram, depending on the strain and your location.
Eighth (⅛ ounce)
An eighth is 3.5 grams.
That is enough for about 3 to 7 joints, depending on how big you roll them, or several sessions with a bong or pipe.
This weed size typically costs $25–$50.
Quarter (¼ ounce)
A quarter is 7 grams of cannabis, enough for roughly 7–14 joints.
Known as a quarter ounce, this amount costs around $50–$80 and is ideal for casual users who smoke a few times a week.
Half (½ ounce)
At 14 grams, a half ounce is great for stocking up if you’re a regular consumer or want to avoid multiple trips to the local dispensary.
Expect to pay $90–$160 for this amount.
Ounce (28 grams)
If you’re buying an ounce (often called a zip), you’re either a frequent smoker or you’re preparing for a party!
One ounce costs $150–$350 and rolls about 28 to 56 joints at 0.5 to 1 gram each.
Quarter pound (113 grams)
A quarter pound (QP) is 4 ounces, or about 113 grams. That works out to 4 zips, 8 half ounces, 16 quarters or 32 eighths.
Commonly called a QP, this is typically bought by people who consume a lot of cannabis or those looking for a bulk purchase.
The cost for a QP ranges from $560 to $1,400.
Half pound (226 grams)
A half pound (HP) is 8 ounces, or about 226 grams (226.8 exactly). That works out to 8 zips, 16 half ounces, 32 quarters or 64 eighths.
A half pound of weed is not for the faint of heart—it’s for growers or people in the cannabis industry.
It weighs as much as a pineapple and costs $1,120 to $2,800.
Pound (453 grams)
A pound is 16 ounces, or about 453 grams (453.6 exactly). That works out to 2 HPs, 4 QPs, 16 zips or 128 eighths.
Weighing in at the size of a watermelon, a pound is most commonly handled by cannabis dispensaries or distributors.
It costs anywhere from $2,000 to $4,000.
How to convert weed measurements
Everything builds from the ounce, so a few simple rules cover almost every conversion:
- 1 ounce = 28 grams = 8 eighths = 4 quarters = 2 halves
- 1 quarter = 7 grams = 2 eighths
- 1 pound = 16 ounces = about 453 grams
The exact figure is 28.35 grams per ounce, so a true eighth is 3.54 grams. Dispensaries round it down and sell eighths as 3.5 grams, quarters as 7 grams and ounces as 28 grams. Check the net weight on the label, since that is what you are paying for.
For joints, a typical joint uses 0.5 to 1 gram. That works out to about 3 to 7 joints from an eighth, 7 to 14 from a quarter and 28 to 56 from an ounce.
What's in a gram?
For a first-time cannabis user or someone with specific needs, starting with a gram is usually the way to go.
This gives you enough for a single joint or a few hits from a pipe. Plus, if you’re sampling different strains, it’s easier to test them out without committing to larger amounts.
The average price for a gram of weed is around $10 to $20, but it can vary depending on where you are and the strain.
Eighths, quarters, and beyond: How much weed do you need?
Once you move past the basic gram, the most common measurement you’ll encounter is the eighth.
If you’re visiting a cannabis dispensary and looking to stock up for the week, an eighth is the go-to option.
It’s enough for several sessions and lets you try different cannabis products without breaking the bank.
- Eighth (⅛ ounce): This is around 3.5 grams, which means you can roll about 3 to 7 joints. It’s enough to last casual users a few days or even a week.
- Quarter (¼ ounce): A quarter ounce will give you about seven grams of cannabis—enough to last longer and ideal for those who prefer having a steady supply on hand.
For those who smoke daily or want to try making edibles, half ounces and ounces are better choices. A quarter ounce (7g) is also the standard ratio for a batch of homemade cannabutter — one stick of butter per quarter.
Not only will these larger amounts last longer, but buying in bulk also tends to be cheaper per gram.
Slang terms for weed measurements
Part of understanding weed measurements means getting familiar with the slang. These terms are often used in cannabis culture and can vary slightly depending on your region. Here are a few:
Dime bag
Typically 1 gram, it gets its name because it used to cost around $10.
Dub
Usually 2 grams for $20.
QP
Short for quarter pound: 4 ounces, or about 113 grams of weed.
HP
Short for half pound: 8 ounces, or about 226 grams of weed.
Zip
An ounce of weed.
Legal limits and considerations
Before you stock up, it’s crucial to know the legal limit in your state.
Many states allow up to one ounce for personal use, while others may have stricter limits.
Exceeding these amounts could land you in trouble, so always check local laws before making a bulk purchase.
Rolling it all up
Knowing your weed measurements not only helps you get the right amount but also ensures you’re not getting shorted or accidentally buying too much.
Whether you’re rolling up a small joint or planning to stock up for a month, understanding the difference between a gram, a quarter ounce, and a pound is essential.
