Weed measurements can feel like a whole second language the first time you walk into a dispensary. From grams and eighths to dubs and zips, the terminology spans decades of cannabis culture — part street slang, part metric system, and entirely worth knowing before you buy. Consequently, this guide breaks down every weed measurement you are likely to encounter, what each one costs, and how much you actually get. For a broader introduction to cannabis, see our
.Weed Measurements: An Overview
The metric system forms the foundation of all weed measurements worldwide. No matter the country or the slang in use, cannabis sells by the gram and the ounce. Nevertheless, even with the enormous variety of nicknames and street terms for cannabis itself, the weights are universally consistent. One ounce equals 28 grams — that number is your anchor for everything that follows.
Modern legal dispensaries largely use weight-based terminology rather than the older cash-value slang. Nevertheless, knowing both systems helps you communicate confidently whether you are at a licensed retailer or talking with a long-time cannabis user. Throughout this guide, slang terms appear in italics on first use to distinguish them from proper weight designations.

One Gram of Weed (A “Dime Bag”)
At virtually every legal dispensary, one gram is the smallest weed measurement available. The slang term dime bag originates from the pre-legalization era, when $10 bought roughly one gram. In practice, however, street-level dime bags were notoriously inconsistent in actual weight.
Today, therefore, dispensaries price each strain per gram based on quality, rarity, and potency. A gram of generic flower typically runs $10–$15 USD. Premium strains with high THC percentages — 28% and above — can reach $20–$25 per gram. Expect to roll two to three joints from a single gram, or fill a moderate blunt. Visually, one gram of cannabis is roughly the size of a grape.
Two Grams — A Simple Weed Measurement With No Bulk Discount
A dub, dub sack, or dub bag historically referred to $20 worth of cannabis — typically two grams. The name derives from “double” the dime. Two grams fills a small ziplock-style bag about halfway when the buds are intact. Alternatively, it appears nearly full when broken down into smaller pieces. At licensed dispensaries, two grams costs twice the price of one. Consequently, this is one of the more straightforward weed measurements — no bulk discount, no mystery.
Eighth of an Ounce — One of the Most Popular Weed Measurements
The eighth is the most popular weed measurement at dispensaries nationwide — and for good reason. At 3.5 grams, an eighth delivers meaningful quantity. Furthermore, it typically comes at a lower per-gram price than buying single grams. Many dispensaries sweeten the deal further by offering four grams for the price of an eighth as a bulk incentive.
How much does an eighth cost?
Expect to pay $20–$25 for budget flower, and up to $50 for premium AAA-grade cannabis. Prices vary considerably by state. For instance, Colorado and Oregon tend to offer competitive prices due to robust local supply, while states with stricter cannabis laws often see higher costs.
How many joints can you roll with 3.5 grams?
Roughly 10–12 small personal joints, depending on how you roll. Visually, 3.5 grams of cannabis is about the size of a kiwi.
Quarter Ounce — A Key Weed Measurement for Regular Smokers
Specifically, a quarter, quad, or set equals one-quarter of an ounce — 7 grams of cannabis. At this weed measurement, bulk pricing typically kicks in. As a result, the per-gram cost runs lower than buying individual grams or eighths.
How much does a quarter ounce cost?
Budget flower typically runs $35–$40. High-quality cannabis can reach $70 or more per quarter, depending on location and strain. Visually, a quarter ounce is roughly the size of an apple — or a solid handful of buds.
How Long Does This Weed Measurement Last?
Generally speaking, even daily smokers can expect a quarter to last at least one week. Occasional smokers can stretch it to a month or beyond. At this weed measurement, proper storage becomes important. See our guide on
to protect your investment from drying out or developing mold.A quarter ounce yields 20 or more small joints, or around 10 full-sized blunts.
One-Half Ounce (The Half-O or Half Zip)
A half-O, half zip, or simply a half contains 14 grams — exactly half of one ounce. This weed measurement delivers some of the best per-gram value short of buying a full ounce, making it a popular choice for regular consumers.
How much does a half ounce cost?
Prices typically range from $90 to $200 USD depending on quality and location. The average sits around $110. At this weed measurement, the per-gram price drops below $10, compared to $12–$15 for single-gram purchases.
Visually, 14 grams of cannabis is comparable to a large grapefruit. It fills roughly one-third of a standard sandwich-sized ziplock bag. Expect approximately 30 personal joints or 20 full-sized blunts from a half-O.
One Ounce — The Maximum Legal Weed Measurement in Most US States
A full ounce — also called a zip or an O — is, notably, the maximum legal possession amount for recreational consumers in most US states. It contains 28 grams. At this weed measurement, dispensaries often offer their best per-gram pricing, making the ounce the most cost-efficient purchase for regular users.
How much does an ounce cost?
Budget flower runs $150–$200. Premium AAA cannabis can reach $300 or more. Visually, 28 grams fills a sandwich ziplock bag and is comparable in size to a peeled coconut.
What can you do with an ounce?
Additionally, beyond smoking, an ounce is a practical quantity for making
, tinctures, and extracts. Expect roughly 8 grams worth of concentrate from one ounce of quality flower. At this weed measurement, you should also expect 50 or more blunts, or close to 100 small personal joints.Storage matters at this quantity
At one ounce, proper storage is essential. Check out our guide on
— a standard ziplock bag is not adequate at this volume, and poor storage leads to dry, harsh smoke and lost potency.One-Quarter Pound (The QP)
Important legal note: No US state permits recreational consumers to possess more than one ounce at a time. Only medical patients in certain states may possess up to six ounces. A quarter pound far exceeds legal personal possession limits everywhere in the US.
A QP contains four ounces — 112 grams of cannabis. As a weed measurement, a quarter pound falls firmly in commercial or cultivation territory. Consequently, it exceeds legal personal possession limits everywhere in the US. For reference, a quarter pound yields well over 300 joints. Even rolling oversized blunts daily, it takes nearly six months to work through a QP. Prices typically range from $800 to $1,500 USD depending on quality and source.
One Pound of Marijuana
As a weed measurement, one pound of cannabis equals 16 ounces — approximately 453 grams. (Note: the minor discrepancy between 448 grams — the theoretical metric conversion — and 453 grams is due to the difference between imperial and metric systems.) This weed measurement exists almost exclusively in the context of commercial cultivation, licensed wholesale, and unfortunately the illegal market. Prices range from $1,500 to $4,000 or more depending on quality.
How Are Cannabis Concentrate Weed Measurements Different?
Cannabis concentrates — wax,
, shatter, oils, and other high-purity extracts — follow the same gram-based weed measurements as flower. However, concentrates carry an additional measurement: THC percentage by weight.Higher THC percentage typically means smaller serving sizes. Moreover, it generally results in a higher per-gram cost. Waxes, shatters, and similar concentrates typically sell in 0.5 to 1 gram quantities. Hash, which often carries a lower THC percentage, usually sells in quantities of 1 gram or larger. Prices fluctuate based on THC percentage, manufacturing process, and strain origin.
Edibles: A Different Kind of Weed Measurement
Edibles use a different measurement system than other weed measurements entirely. Rather than grams of cannabis, edibles list THC content in milligrams (mg) — typically as a total amount for the entire product rather than per serving.
For example, a dispensary brownie labeled “100mg THC” contains 100 milligrams of THC in the whole product. Cutting it into quarters gives roughly 25mg per piece — a much more manageable dose for most users. For beginners, 5–10mg is a common starting point. See our
for a current breakdown of dosed products across every format.For loose items like gummies, simply divide the total THC listed on the package by the number of pieces inside. A bag labeled “250mg THC” containing 25 gummies works out to 10mg per gummy — straightforward math that makes dosing reliable. Prices for edibles range widely. That said, $20–$30 USD covers many solid options at the entry level.
Weed Measurements: Wrapping Up
Weed measurements span decades of cannabis culture — from the imprecise street-level dime bag to the precisely weighed dispensary ounce. As legalization matures and regulated retail becomes the norm, therefore, the older cash-value slang is gradually giving way to clear weight-based terminology. That is genuinely good news for consumers: knowing your weights means knowing exactly what you are buying, at what price, and whether you are getting value.
Walk into any dispensary with a solid grasp of weed measurements and you will have everything you need to shop confidently, communicate clearly with your budtender, and make purchases that actually suit your needs. Happy shopping — and as always, happy smoking.
