How Many Grams in an Ounce of Weed? (2026 NJ Guide)
There are 28 grams in an ounce of weed. See our complete NJ cannabis weight guide with conversion charts, real dispensary prices, and legal purchase limits.
There are 28 grams in one ounce of weed (28.3495 grams to be exact). Whether you are visiting a New Jersey dispensary for the first time or simply want to understand cannabis measurements before you shop, this guide breaks down every weight from a single gram to a full ounce with NJ-specific pricing, legal purchase limits, and practical size comparisons.
Cannabis measurements can feel confusing when you are new. Dispensary menus list eighths, quarters, and halves with no explanation, and the pricing jumps can seem random if you do not know how the math works. The good news is that the system is straightforward once you see it laid out. And once you understand it, you will make smarter buying decisions every single time you shop.
As budtenders at The Library in West Orange, we walk new customers through these measurements multiple times a day. This guide captures everything we explain at the counter, plus the NJ-specific legal context and pricing data that no national guide includes.

Understanding Cannabis Measurements: From Gram to Ounce
Every dispensary in New Jersey uses the same measurement system. Here is what each weight looks like, what it costs, and who it is best for. We have included size comparisons to everyday objects so you know exactly what to expect when your budtender hands you the bag.
The Gram (1g) — The Starting Point
About the size of a small grape or a penny stacked 3 high
NJ Price Range
$10-$15
Yields
1-2 joints or 2-3 bowls
Common Slang
G, single, dime bag
Budtender Pro Tip
If you are trying a new strain, start with a gram before committing to a larger purchase. It is the lowest-risk way to figure out what you like. Interested in gentle exploration? Our microdosing guide explains how to use small amounts effectively.
The Eighth (3.5g) — The Most Popular Purchase
About the size of a golf ball or large walnut
NJ Price Range
$30-$55
Yields
3-7 joints depending on roll size
Common Slang
Eighth, slice, half-quarter, cut
Why It Is the Most Popular
The eighth hits the sweet spot between affordability and quantity. It is enough for a light consumer to last a week or two, small enough to try premium strains without overspending, and the per-gram price starts dropping compared to buying singles. If you are not sure what size to buy, start here.
The Quarter (7g) — The Sweet Spot for Value
About the size of an apple or large kiwi
NJ Price Range
$55-$95
Yields
7-14 joints
Common Slang
Quarter, quad, Q
Budtender Pro Tip
Quarters usually offer the best value-per-gram at NJ dispensaries. The price break from an eighth to a quarter is significant, making this the ideal size for regular consumers who have found a strain they enjoy. Most of our returning customers buy at this size. Check out our guide on NJ cannabis pricing for a deeper breakdown.
The Half Ounce (14g) — The Bulk Saver
About the size of a grapefruit or baseball
NJ Price Range
$90-$160
Yields
14-28 joints
Common Slang
Half, half-O, half zip
Budtender Pro Tip
Buying a half ounce makes financial sense when you have found your go-to strain and consume regularly. The per-gram savings are substantial compared to buying multiple eighths. Just make sure you store your cannabis properly so the last gram is as fresh as the first.
The Ounce (28g) — The Maximum NJ Purchase
About the size of a softball or small coconut
NJ Price Range
$160-$300
Yields
28-56 joints (or more with smaller rolls)
Common Slang
Zip, O, zone, lid
Important NJ Legal Note
One ounce (28g) is the maximum amount of cannabis flower you can purchase in a single transaction at a New Jersey dispensary. This is set by the NJ Cannabis Regulatory Commission. For heavy consumers, buying at the ounce level delivers the absolute best price per gram. Proper cannabis storage is essential at this quantity to maintain freshness over weeks of use.
Why Visual Estimates Are Unreliable
Cannabis density varies dramatically by strain. A fluffy sativa ounce can look two or three times larger than a dense indica ounce at exactly the same weight. This is why dispensaries weigh everything on calibrated digital scales rather than eyeballing it. If you are ever unsure, check our indica vs. sativa guide to understand why different strains look and feel so different at the same weight.

Browse MenuBeyond the Ounce: Larger Cannabis Measurements
These larger measurements are included for educational reference. They exceed NJ personal purchase limits and are used in wholesale cultivation and industry contexts only.
Quarter Pound (QP) — 113g / 4 oz
Used in wholesale, cultivation, and licensed distribution. Consumers will never encounter this measurement at a dispensary counter. Exceeds NJ personal purchase and possession limits.
Slang: QP, quarter pack, quap
Pound — 453g / 16 oz
Industry-level measurement used by licensed cultivators, processors, and distributors. Consumers never encounter this measurement in legal retail settings. Possession of this amount without a license carries serious legal consequences in NJ.
Slang: pack, elbow, LB
Legal Reminder
In New Jersey, purchasing cannabis beyond the 1-ounce transaction limit or possessing amounts exceeding legal thresholds without proper licensing can result in criminal penalties. Always purchase from licensed dispensaries and stay within legal limits. For the most current regulations, visit the NJ Cannabis Regulatory Commission.
NJ Cannabis Purchase Limits & Legal Context
Understanding NJ cannabis law is just as important as understanding measurements. Here is what every consumer needs to know about legal purchase and possession limits in New Jersey as of 2026.
Recreational Purchase Limit
1 ounce (28 grams) of cannabis flower per transaction. This is a per-transaction limit, not a daily limit. You may visit multiple dispensaries in a day, but each transaction is capped at 1 ounce.
Possession Limit
Up to 6 ounces (170 grams) of usable cannabis with a valid explanation of legal purchase (e.g., dispensary receipts). Amounts between 1 and 6 ounces are decriminalized but should be accompanied by proof of legal purchase.
Medical Patient Limits
NJ medical cannabis patients may have higher monthly allotments than recreational consumers. Specific limits depend on the patient's prescription and the NJ Cannabis Regulatory Commission guidelines. Medical patients also benefit from tax exemptions.
NJ Cannabis Tax Structure
NJ applies a social equity excise fee and local municipality tax on cannabis purchases, which affects final retail pricing. Medical cannabis purchases are exempt from sales tax. The tax rate can add approximately 7-12% to the base price depending on municipality.
Source: These limits are set by the NJ Cannabis Regulatory Commission (NJCRC) under the New Jersey Cannabis Regulatory, Enforcement Assistance, and Marketplace Modernization Act. For the most current regulations and any updates, visit nj.gov/cannabis.
NJ Dispensary Pricing: What You Will Actually Pay in 2026

Get DirectionsCannabis Weight by Product Type
Cannabis is not just flower anymore. Different product types use different measurement systems, and understanding this prevents confusion at the dispensary counter. One gram of concentrate is not the same experience as one gram of flower.
Edibles
Edibles are measured in milligrams (mg) of THC, not grams of product weight. The physical weight of a gummy or chocolate is irrelevant. What matters is the cannabinoid content per serving.
- NJ standard: 10mg THC per serving, 100mg THC per package
- Beginner dose: 2.5mg-5mg (start low, go slow)
- Experienced dose: 10mg-25mg per serving
- NJ price range: $20-$45 per package (100mg)
New to edibles? Read our edibles dosing guide for beginners and our best edibles in NJ for product recommendations.
Vape Cartridges
Vape cartridges are measured in grams of oil, but the experience per gram is vastly more potent than flower due to concentration.
- Standard sizes: 0.5g and 1g cartridges
- Puffs per gram: approximately 100-200 draws
- THC concentration: typically 70-90%
- NJ price range: $30-$55 (0.5g), $50-$80 (1g)
Want a detailed breakdown? See our THC vape cartridge guide.
Concentrates (Wax, Shatter, Live Resin)
Concentrates are sold by the gram, but a single gram goes much further than a gram of flower because of the dramatically higher potency.
- Standard sizes: 0.5g and 1g
- THC concentration: 60-90% (vs. 15-30% for flower)
- 1g of concentrate is equivalent to roughly 3-4 grams of flower in terms of total THC content
- NJ price range: $40-$70 (0.5g), $60-$100 (1g)
Pre-Rolls
Pre-rolls are measured by the weight of flower inside the paper. They offer convenience at a slight per-gram premium compared to loose flower.
- Standard sizes: 0.5g, 0.75g, 1g singles
- Multi-packs: 5-pack (2.5g-3.5g total), 7-pack or 10-pack
- Infused pre-rolls: enhanced with concentrates for 35-50%+ THC
- NJ price range: $8-$15 (singles), $25-$55 (multi-packs)

Key Takeaway on Product Weights
A gram is a gram by weight, but the effects vary enormously by product type. One gram of flower with 25% THC contains about 250mg of THC. One gram of concentrate at 80% contains 800mg. One gram of edible product might contain only 10mg. Always pay attention to the THC content, not just the physical weight, when comparing products.
Cannabis Slang Dictionary: Every Weight Term Explained
Cannabis has its own language, and weight slang has evolved over decades. Whether you hear these terms from friends, see them online, or come across them in pop culture, here is what they all mean. You do not need to use these at a dispensary, but knowing them helps you understand what people are talking about.
| Slang Term | Meaning |
|---|---|
| Nick / Nickel bag | $5 worth of cannabis |
| Dime bag | $10 worth (~1g) |
| Dub | $20 worth (~1.5-2g) |
| Slice | Eighth (3.5g) |
| Quad / Q | Quarter (7g) |
| Half-O | Half ounce (14g) |
| Zip | Ounce (28g) |
| Zone | Ounce (28g) |
| Lid | Ounce (28g) |
| O | Ounce (28g) |
| QP | Quarter pound (113g) |
| Elbow | Pound (453g) |
| Key / Kilo | Kilogram (1,000g) |
A note on dispensary etiquette: While these slang terms are widely understood, NJ dispensaries use standard measurement terms on their menus and labels. You can absolutely use slang when talking with your budtender (we hear it all day), but official packaging and receipts will always list the precise weight in grams.
How to Weigh Cannabis at Home
Dispensary products are weighed on calibrated commercial scales before packaging, but it is perfectly reasonable to verify your purchase at home. Here is how to do it accurately.
Get a Digital Scale
Purchase a digital scale with 0.01g precision. Affordable options under $20 are available on Amazon and at kitchen supply stores. Look for a scale that reads to at least two decimal places for accuracy.
Place a Container on the Scale
Put a small dish, shot glass, or piece of parchment paper on the scale platform. This holds the cannabis without losing any material on the scale surface.
Press "Tare" or "Zero"
Hit the tare button to reset the display to 0.00g with your container on it. This ensures you are only measuring the weight of the cannabis, not the container.
Add Your Cannabis
Carefully place your flower into the container. Avoid breaking up buds if you want to verify the total weight. Handle by the edges of the container to keep oils off the scale platform.
Read the Measurement
Wait 2-3 seconds for the display to stabilize, then read the weight. Your dispensary purchase should be within 0.1g of the labeled weight. Note that packaging weight (bag, label) should not be included.
Why Visual Estimation Fails
Two different strains at exactly 3.5 grams can look wildly different in your hand. Dense indica buds take up much less space than airy sativa buds at the same weight. A scale removes all guesswork. If your strongest strains look smaller, it is usually because density increases with potency, not because you received less product.
What If My Weight Is Off?
Licensed NJ dispensaries use commercial-grade, regularly calibrated scales. If your home scale shows a discrepancy of more than 0.2g, first check that your own scale is calibrated correctly (most come with a calibration weight). Minor differences are normal due to moisture loss during transport. If there is a significant discrepancy, contact the dispensary. Reputable dispensaries will make it right.
