Cannabis Flower Measurements Explained: From Grams to Ounces
| Quick Answer
Cannabis flowers are commonly measured in grams, while ounces are used for larger quantities. One ounce equals approximately 28.35 grams; in everyday product listings, an ounce is often rounded to 28 grams. Knowing these measurements helps you compare package sizes and price per gram without relying on slang or guesswork. |
Why Cannabis Weight Matters
The weight shown on a product listing tells you how much flower is in the package, not how strong it is. Two products with the same weight can have different THC and CBD levels, aromas, and terpene profiles. Check both the net weight and the product details before comparing options.
For shoppers browsing cannabis flower options, the listed quantity is a useful starting point. Check the individual product page for the stated weight and other available information.
Cannabis Measurements at a Glance
These are common gram-to-ounce equivalents you may see in product discussions:
| Common term | Approximate weight | Useful conversion |
|---|---|---|
| Gram | 1 g | About 1/28 of an ounce |
| Eighth | 3.5 g | ⅛ ounce |
| Quarter | 7 g | ¼ ounce |
| Half-ounce | 14 g | ½ ounce |
| Ounce | About 28 g (28.35 g precisely) | 1 ounce |
What Do the Common Terms Mean?
Gram: a small quantity
A gram is a straightforward unit for comparing smaller packages. It can be useful when you want to compare a product without committing to a larger quantity. The visible size of a gram can vary because flower density, bud shape, and moisture affect how much space it occupies. Appearance alone is not a reliable way to measure weight.
Eighth and quarter: fractional ounces
An eighth means one-eighth of an ounce and is commonly listed as 3.5 grams. A quarter means one-quarter of an ounce, or about 7 grams. These names are shorthand for weight, so check the net quantity printed on the listing or package.
Half-ounce and ounce: larger quantities
A half-ounce is approximately 14 grams, while an ounce is about 28.35 grams. Listings may round an ounce to 28 grams for convenience. When comparing different quantities, calculate the price per gram rather than assuming a larger package is automatically better value.
How to Compare Weight and Value
Package price alone can be misleading when quantities differ. To compare like with like, divide the listed price by the net weight in grams. For example, a hypothetical 7 g package priced at $70 works out to $10 per gram, while a 3.5 g package at $42 works out to $12 per gram. The first has a lower price per gram, but the right choice still depends on your budget, storage and whether you will use the quantity before quality changes.
Before comparing listings, check these details:
- Net weight in grams, rather than the package size or how full it looks.
- Price per gram, especially when comparing different quantities.
- THC and CBD information, which describes cannabinoid content rather than weight.
- Packaging date and recommended storage conditions where provided.
Does Weight Tell You About Potency?
No. Weight and potency describe different things. A 3.5 g package does not automatically contain more or less THC per gram than a 7 g package. Read cannabinoid information separately and avoid treating strain names as a guarantee of strength. For example, cannabis indica strains may be described using familiar category labels, but those labels do not replace the product’s own details.
The same principle applies to cannabis concentrates. Concentrates are a different product format, so their net weight and cannabinoid information should not be compared directly with dried flowers by weight alone. For Canadian products, Health Canada explains label information, including net weight and THC/CBD details, in its guide to reading and understanding cannabis product labels.
Quick FAQs
How many grams are in an ounce of cannabis?
A standard ounce is 28.35 grams. Cannabis listings commonly round this to 28 grams.
Is an eighth the same as 3.5 grams?
Yes. An eighth is one-eighth of an ounce and is commonly represented as 3.5 grams.
Does a larger package mean better value?
Not always. Compare the price per gram, product details, and package information before deciding.
Can I estimate weight by looking at the buds?
Visual estimates are unreliable because bud density and shape vary. Use the stated net weight on the product listing or packaging.
Are grams used for cannabis concentrates too?
Concentrates may also be labelled by weight, but they are a different product category. Compare their own label information rather than assuming the same weight means the same potency as flower.
Bottom Line
Remember the basic conversions: 3.5 g is an eighth, 7 g is a quarter, 14 g is a half-ounce and an ounce is about 28 g. Use the net weight and price per gram to compare quantities, then check cannabinoid details and label information separately.
