How Many Grams Is a Half Ounce? Your Quick Answer
A half ounce of cannabis is 14 grams. More precisely, it's 14.17 grams, but dispensaries round down to 14 grams for simplicity. That's four eighths or two quarters.
Half Ounce vs. Eighth, Quarter, and Full Ounce: A Quick Comparison
Understanding where a half ounce fits among other common cannabis measurements helps you gauge value and portion size. Here's how they stack up:
| Measurement | Grams | Relative Size | Typical Use |
|---|---|---|---|
| Eighth (1/8 oz) | 3.5g | Small | A few sessions or a week for light users |
| Quarter (1/4 oz) | 7g | Medium | About a week for regular users |
| Half ounce (1/2 oz) | 14g | Large | Two weeks or more for most |
| Full ounce (1 oz) | 28g | Bulk | Monthly supply for heavy users |
As you can see, a half ounce is a solid middle ground, offering more bud than a quarter but still manageable for personal use.
How Many Grams Are in a Half Ounce?
The direct answer: a half ounce equals 14 grams. That's the standard used by dispensaries across the US, including in San Francisco.
| Unit | Grams (exact) | Grams (dispensary) |
|---|---|---|
| 1/2 ounce | 14.17g | 14g |
| 1 ounce | 28.35g | 28g |
| 1/4 ounce | 7.09g | 7g |
| 1/8 ounce | 3.54g | 3.5g |
When you buy a half ounce at a dispensary, you'll receive 14 grams. The tiny difference (0.17g) is negligible and typically not reflected in pricing or packaging.
Ounces to Grams: The Simple Conversion Formula
To convert any ounce amount to grams, multiply by 28.35. For example, 0.5 oz × 28.35 = 14.175g, which rounds to 14g.
| Ounces | Calculation | Grams |
|---|---|---|
| 0.5 oz | 0.5 × 28.35 | 14.17g (≈14g) |
| 1 oz | 1 × 28.35 | 28.35g (≈28g) |
| 0.25 oz | 0.25 × 28.35 | 7.09g (≈7g) |
| 0.125 oz | 0.125 × 28.35 | 3.54g (≈3.5g) |
Remember: 1 ounce is heavier than 1 gram (an ounce is about 28 times heavier). So if you're converting from grams to ounces, divide by 28.35 instead.
Why Some Say 14 Grams and Others Say 14.17: The Exact Answer
Both numbers are correct, but they serve different purposes. The exact conversion is 14.17 grams, but the cannabis industry rounds to 14 grams for simplicity and consistency.
| Number | Context | Why |
|---|---|---|
| 14g | Dispensary purchases | Standardized, easy to package and price |
| 14.17g | Scientific/legal | Precise metric conversion |
If you're buying a half ounce, expect 14 grams. If you're calculating for a recipe or lab, use 14.17g. The difference is less than a fifth of a gram—not something you'll notice in your bag.

Is a Half Ounce Right for You? How Much and How Long It Lasts
A half ounce is a great choice if you consume regularly but don't want to commit to a full ounce. It typically lasts a casual user 2–4 weeks, a moderate user 1–2 weeks, and a heavy user a few days to a week.
| Factor | Why It Matters | Typical Range |
|---|---|---|
| Frequency | How often you use affects how long it lasts | Daily vs. occasional |
| Method | Joints, bowls, or vaporizers use different amounts | Varies by method |
| Tolerance | Higher tolerance means more consumption | Varies by individual |
If you're unsure, start with a quarter and see how long it lasts. A half ounce offers better value per gram than smaller amounts, but only if you'll use it.
