When it comes to cannabis measurements, knowing how much an 8th weighs compared to an ounce is important for consumers and sellers alike. An 8th refers to an eighth of an ounce, while an ounce (abbreviated as oz) is a unit of measurement equaling 28 grams.
Quick Answer
An eighth (1/8) of an ounce is equal to 3.5 grams. So it takes 8 eighths to make up one ounce, which is 28 grams. An eighth is a common quantity for cannabis purchases, while an ounce is a standard unit used by dispensaries and growers.
What is an 8th?
An eighth, commonly abbreviated as 8th, is a measurement of weight equal to one eighth of an ounce. Since one ounce equals 28 grams, one eighth of an ounce is equal to 3.5 grams. Some other key facts about 8ths:
- An 8th is a popular amount for cannabis purchases, ideal for 1-2 people.
- Most dispensaries sell cannabis flower in quantities of 1 gram, 3.5 grams (8th), 7 grams, 14 grams (half oz) and 28 grams (full oz).
- Buying cannabis in 8ths is more economical than buying by the gram, but allows you to sample strains without committing to a full ounce.
- The term “8th” comes from dividing an ounce into 8 equal portions, each weighing 3.5 grams.
What is an Ounce?
An ounce (abbreviated oz) is a unit of weight measurement. When used for cannabis, one ounce is equal to 28 grams. Some key facts about ounces:
- An ounce is a common unit for measuring cannabis flower quantities by dispensaries and growers.
- Often cannabis will be sold in full ounce (28g) increments or half ounce (14g) increments.
- One ounce is generally enough to roll between 28-40 joints, depending on rolling methods.
- Buying cannabis flower in ounce increments will be more economical compared to buying by the gram or 8th if you are a frequent consumer.
How Many 8ths are in an Ounce?
Since an 8th equals 3.5 grams, and there are 28 grams in an ounce, there are 8 eighths (8 x 3.5g) in 1 ounce (28g).
Here is a visual breakdown of the math:
- 1 ounce = 28 grams
- 1 eighth = 3.5 grams
- 28 grams divided by 3.5 grams = 8
So there are 8 eighths in every ounce. This makes an eighth exactly one eighth the weight of a full ounce.
8ths to Ounces Conversion Table
Here is a conversion table showing how many 8ths are in various ounce measurements:
| Ounces | Grams | 8ths |
|---|---|---|
| 1 oz | 28 g | 8 |
| 2 oz | 56 g | 16 |
| 3 oz | 84 g | 24 |
| 4 oz | 112 g | 32 |
| 16 oz (1 lb) | 448 g | 128 |
As shown, a single ounce contains 8 eighths. The number of 8ths scales accordingly for larger ounce measurements. A pound (16 oz) contains 128 eighths. This conversion allows you to easily determine the number of 8ths based on total ounces.
Pricing Differences Between 8ths and Ounces
When purchasing cannabis, you’ll generally find better savings buying in ounce increments vs. 8ths. However, pricing and value depend on a few factors:
- Dispensary Pricing – Many dispensaries offer discounted rates when buying larger quantities like ounces vs. 8ths. The per gram price is usually lowest for ounces.
- Strain Quality – Higher quality strains tend to command more value per gram compared to average quality. High quality 8ths may be priced similarly to average ounces.
- Purchase Frequency – For frequent consumers buying at least an 8th a week, ounces will offer more savings long term than repeated 8th purchases.
For example, a dispensary may price 8ths of a certain strain at $35, while ounces of the same strain cost $200. Although the upfront cost is higher, the per gram rate for the full ounce is only about $7 vs. $10 per gram for the 8th. For frequent buyers, the savings are significant when purchasing ounces.
Why Buy 8ths Instead of Ounces?
Buying cannabis by the 8th does have some advantages compared to ounces, depending on your needs:
- Sample New Strains – 8ths allow you to try out multiple strains without committing to a full ounce of one strain.
- Convenient Quantities – 8ths are handy portions for 1-2 people without excess leftovers.
- Within Budgets – The lower cost of 8ths may suit budgets better than buying a full ounce at once.
- Test Quality – With 8ths, you can first test out a strain’s quality before purchasing more.
For these reasons, casual or first-time consumers may prefer buying 8ths. However, frequent consumers will get better value purchasing full ounces.
Comparing Cannabis Prices by Weight
When purchasing cannabis, it’s helpful to understand prices across standard weight measurements. Here’s an overview of typical price ranges by quantity:
- Gram: $10-$15
- 8th: $30-$60
- Quarter Ounce (7g): $70-$100
- Half Ounce (14g): $130-$200
- Ounce (28g): $200-$300+
As shown, the per gram price declines significantly when buying in ounce increments vs. grams or 8ths. Dispensaries may offer deals for buying full ounces as well, like “mix-and-match” options allowing you to select multiple strains.

Legality of 8th and Ounce Purchases
When purchasing 8ths, ounces, or any amount of cannabis, it’s essential to follow state laws and possession limits. Here are some key legal considerations:
- In legal states, adults 21+ can purchase up to 1 oz of cannabis flower per transaction from licensed dispensaries.
- Purchasing 8ths, ounces, or any amount over state possession limits can result in criminal charges.
- Transporting purchased cannabis across state lines is illegal under federal law, even when traveling between legal states.
- Consuming cannabis in public areas remains illegal in states where recreational use is permitted.
- Employers, public housing, schools, and other entities may prohibit possession or use of any amount, even if legally purchased.
Carefully follow your state’s laws by only purchasing legal possession amounts and consuming cannabis in authorized private areas to avoid potential legal issues.
Does an Ounce Seem Like a Lot of Weed?
For first-time or occasional cannabis consumers, an ounce may seem like an extremely large quantity of marijuana. However, frequent users may go through an ounce every week or two. Here are some perspectives on ounce quantities:
- Casual smokers may make an 8th last 2+ weeks, making an ounce seem like a 6-8 month supply.
- Frequent users with high tolerances often consume 1 gram or more per day, using up an ounce in 4 weeks or less.
- Patients using cannabis for medical conditions may require an ounce every few weeks to maintain consistent relief.
- People who cook with cannabis or make infused oils/extracts may use several ounces per month for their products.
While 28 grams sounds like a lot to non-frequent users, regular cannabis consumers can use an ounce in a reasonable timeframe. Understanding your personal usage rate will determine whether buying by the ounce makes sense based on your needs.
Storing Leftover Cannabis
When buying in bulk, you may not use up all your cannabis right away. Proper storage is important for keeping leftover flower fresh until needed. Recommended storage tips include:
- Store in an airtight glass jar or container away from light and heat to preserve terpenes.
- Use Boveda or Integra humidity control packs to maintain optimal moisture content.
- Keep out of reach of children in a locked cabinet or safe if needed.
- Open container to allow gas exchange once a week for 5 minutes.
- Inspect buds and remove extremely dry or moldy portions before re-sealing.
Stored properly in a cool dark place, cannabis flower can retain quality and freshness for several months. Refrigeration is not needed for short-term storage, and may actually degrade trichomes over time.
Conclusion
Knowing eighth and ounce equivalents is helpful for purchasing flower according to your consumption habits. An 8th can be ideal for light, occasional use, while buying full ounces offers savings for frequent cannabis users. Legally purchase within possession limits, compare dispensary pricing, and use best storage practices to get the most out of your quantity. Understanding measurements like 8ths vs. ounces allows you to make informed decisions when buying cannabis flower.
