How Many Grams Is a Quarter Ounce?

A quarter ounce, universally shortened to a "quarter" in cannabis culture, is exactly 1/4 of a standard ounce. Since one ounce equals 28.3495 grams in the metric system, dividing that by four gives us the precise figure:

1 Quarter Ounce = 28.3495 divided by 4 = 7.0874 grams

In the cannabis industry, this is almost always rounded to 7 grams. When you buy a quarter at a dispensary, you will typically receive exactly 7.0 to 7.1 grams of cannabis flower.

The quarter ounce is the most popular standard cannabis measurement purchased in the United States. It represents a substantial amount for most consumers, enough for regular personal use over several days to a few weeks depending on your consumption habits, while remaining affordable compared to larger quantities like a half ounce or full ounce.

At a licensed dispensary, the weight on the label is required by law to be accurate. However, having a reliable kitchen scale at home lets you double-check any purchase. A true quarter will always read between 7.0 and 7.1 grams on a properly calibrated digital scale.

How Many Grams Is a Quarter of an Oz? Step-by-Step

  1. Start with the exact weight of 1 ounce: 28.3495 grams
  2. Divide by 4, since a quarter equals 1/4: 28.3495 / 4 = 7.08738 grams
  3. Rounded to 4 decimal places: 7.0874 grams
  4. Standard industry rounding: 7 grams

How Many Grams Is a Quarter Pound?

A quarter pound is a much larger quantity, exactly 1/4 of a pound. Since one pound equals 453.592 grams, a quarter pound works out to:

1 Quarter Pound = 453.592 divided by 4 = 113.398 grams

This is commonly rounded to 113.4 grams, or simply 113 grams. A quarter pound equals 4 ounces, or the equivalent of 16 quarters.

To be clear, because this causes frequent confusion:

  • Quarter ounce = 7 grams, the everyday purchase at a dispensary
  • Quarter pound = 113.4 grams, a bulk wholesale quantity that is 16 times larger

In the cannabis industry, a quarter pound is a wholesale-level quantity. It is rarely sold at retail dispensary counters since most states cap personal possession at 1 ounce (28g) for adults. A quarter pound is more relevant for licensed growers, distributors, and regulated businesses within the cannabis industry.

Complete Cannabis Measurement Chart

Cannabis is typically measured in a hybrid system: the names come from the imperial system (ounces, pounds), but the quantities are almost always discussed and labeled in grams. Here is the complete reference table every cannabis consumer should know:

Common NameFractionExact GramsRounded GramsApprox. Joints

Pro Tip: The joint count column above assumes 0.5 to 1 gram per joint. Blunts typically use 1 to 2 grams each, so a quarter ounce (7g) would yield roughly 3 to 7 blunts. Your exact yield depends on your personal consumption habits and rolling style.

Why Cannabis Uses the Imperial System

If you have ever wondered why cannabis is sold in ounces and pounds rather than clean metric units, you are not alone. Cannabis weights are a fascinating artifact of history. Long before legalization, the underground cannabis market in the United States developed its own informal measurement standards based on the imperial system, the same system used for most everyday US commerce.

When US states began legalizing cannabis, regulators naturally adopted the existing vocabulary that consumers and the cannabis industry already understood: grams, eighths, quarters, halves, and ounces. This hybrid approach, imperial names with metric actual weights, became the standard unit of commerce in modern cannabis retail.

Most other countries that have legalized cannabis (Canada, Germany, the Netherlands) use purely metric measurements. But in the US, expect to hear imperial fraction names at every dispensary. The standard cannabis measurement in the US is the ounce and its fractions, even if the gram is what gets printed on the label.

Visual Size Guide: What Does a Quarter Look Like?

One of the most common points of confusion for new cannabis consumers is that the same weight can look dramatically different depending on the product. A quarter ounce (7 grams) of cannabis flower is not a fixed visual size.

Dense vs. Airy Buds

The density of cannabis flower depends heavily on the strain type and how the cannabis was grown, trimmed, and cured. Indica-dominant strains tend to produce dense, compact buds that are smaller in volume but heavier per bud. Sativa-dominant and hybrid strains often produce airy buds with a more open structure, taking up significantly more space for the same weight.

  • Dense buds: 7 grams may fit in the palm of your hand and look like 2 to 3 large nuggets
  • Airy buds: 7 grams of premium flower might fill a small sandwich bag loosely
  • Both weigh the same: exactly 7 grams on a kitchen scale
Pro Tip: Never judge a quarter by eye. The visual volume of cannabis varies enormously by strain, grow method, and trim quality. A kitchen scale is the only reliable way to verify the exact weight of what you purchased. At a licensed dispensary, the weight is pre-verified and labeled by law, but owning a scale gives you personal peace of mind.

How Much Space Does a Quarter Take Up?

  • 7 grams (quarter) fits comfortably in a small 4 oz airtight glass jar
  • 14 grams (half ounce) fits in a medium 8 oz jar
  • 28 grams (full ounce) typically requires a large 16 oz pint jar

How to Weigh Cannabis Accurately

Whether you are verifying a purchase, portioning for recipes, or simply curious about what you have, knowing how to accurately weigh cannabis is a practical and essential skill for cannabis consumers.

Step-by-Step: Using a Digital Kitchen Scale

  1. Choose the right scale: Use a digital kitchen scale that measures to 0.1 gram precision at minimum. Scales measuring to 0.01g are even better for small quantities.
  2. Calibrate first: Many digital scales include a calibration weight. Use it regularly to ensure accuracy.
  3. Use a container: Place a small bowl, plate, or piece of paper on the scale. Press the tare (zero) button to reset the display to 0.0g with the container in place.
  4. Add your cannabis: Gently place your cannabis flower or buds into the container.
  5. Read the weight: A genuine quarter ounce will display between 7.0 and 7.1 grams.
What the scale should read for each common quantity:
• 1 gram: 0.9 to 1.1 g
• Eighth (1/8 oz): 3.4 to 3.6 g
• Quarter (1/4 oz): 7.0 to 7.1 g
• Half ounce (1/2 oz): 14.1 to 14.2 g
• Full ounce: 28.3 to 28.4 g

How Much Does a Quarter Cost? Price Guide by Market

The cost and price of a quarter ounce of cannabis is one of the most searched questions for both new and experienced consumers. The honest answer: it varies depending on several factors. Here is a breakdown of what drives the price you see at a dispensary.

Factors That Affect the Price of a Quarter

  • Strain type and THC content: Premium flower with high THC content and potency commands a higher price. Budget strains cost significantly less.
  • Quality tier: Top-shelf, mid-shelf, and value (bottom-shelf) cannabis can vary by $20 to $40 per quarter at the same dispensary.
  • State and local taxes: Cannabis taxes vary enormously. California adds 15% excise plus city taxes. Oregon has lower taxes, making prices more competitive. State and local taxes can add 20% to 40% to the base price.
  • Local market competition: In states with many licensed dispensaries, competitive prices are lower. Newer markets with fewer dispensaries tend to have higher costs.
  • Indoor vs. outdoor grow: Indoor cannabis typically sells for more due to higher production costs. Sun-grown outdoor cannabis is usually less expensive.

Average Price of a Quarter Ounce by Market Tier

Market / TierPrice (Before Tax)Price (After Tax, est.)
Dispensary - Budget / Value Flower$20 to $35$25 to $50
Dispensary - Mid-Shelf Flower$35 to $55$45 to $75
Dispensary - Top-Shelf / Premium Flower$55 to $80$70 to $110
Dispensary - Craft / Exotic Strains$75 to $100+$95 to $130+

Before you invest in any purchase, it is smart to compare prices across dispensaries in your area. Many dispensary websites and apps list menu prices including taxes so you can compare competitive prices before walking in. Buying in larger quantities, a half ounce or full ounce, often reduces the effective cost per gram significantly.

Pro Tip: Do not let price alone push you toward buying more than you need. The cannabis industry has made bulk buying accessible, but larger quantities increase the importance of proper storage. If you cannot store a full ounce correctly, a quarter ounce may offer better value by preserving quality and potency.

Proper Storage: How to Keep a Quarter Fresh

Proper storage is one of the most underrated factors affecting your cannabis experience. Even the highest-quality premium flower will degrade quickly if stored incorrectly. Here is the essential guide to keeping your quarter ounce at peak quality.

The Ideal Storage Setup

The gold standard for cannabis storage is an airtight glass jar, specifically a mason jar or purpose-built cannabis container with a tight-sealing lid. Glass is chemically inert and will not transfer any odors or chemicals to your flower, unlike plastic bags or containers which can affect both flavor and potency over time.

  • Container: Airtight glass jar (4 oz size is perfect for a quarter)
  • Temperature: Cool room temperature, ideally 60 to 70 degrees F (15 to 21 degrees C)
  • Humidity: 59% to 63% relative humidity (use a Boveda pack for precision control)
  • Light: Store away from direct light, as UV rays degrade THC content and potency
  • Location: A drawer, cabinet, or closet works well

What Degrades Cannabis Quality?

FactorEffect on CannabisHow to Avoid It
Heat (above 77 degrees F)Dries out trichomes, degrades THCStore in a cool location
UV LightBreaks down cannabinoids, reduces potencyUse opaque or dark glass jars
High Humidity (above 65% RH)Promotes mold and mildew growthUse humidity packs, avoid bathrooms
Low Humidity (below 55% RH)Dries out flower, makes smoke harshHumidity packs maintain 59 to 63%
Oxygen exposureOxidizes THC into CBN over timeKeep a tight airtight seal
Plastic bagsStatic damages trichomes; chemicals may leachAlways use glass containers

When stored properly in an airtight glass jar under the right conditions, a quarter ounce of cannabis flower can stay fresh and potent for 6 months to 1 year. Most consumers use a quarter within 2 to 4 weeks, which makes proper storage easy to maintain.

Quarter vs. Larger Quantities: Is Bulk Buying Worth It?

One of the most practical questions cannabis consumers face is whether to invest in a larger quantity to save money. Let us look at the cost-per-gram math for bulk buying compared to purchasing a quarter at a time.

Cost Per Gram Comparison (Mid-Shelf Example)

QuantityGramsApprox. Cost (mid-shelf)Cost Per Gram
1 gram1 g$10 to $15$10 to $15 per gram
Eighth (1/8 oz)3.5 g$25 to $40$7 to $11 per gram
Quarter (1/4 oz)7 g$35 to $55$5 to $8 per gram
Half ounce (1/2 oz)14 g$60 to $90$4 to $6 per gram
Full ounce (1 oz)28 g$99 to $160$3.50 to $6 per gram

The math clearly shows that larger quantities offer better value per gram. However, there are real-world considerations that make the quarter ounce the practical sweet spot for most cannabis consumers:

  • Freshness: Cannabis is best consumed within 2 to 4 weeks of purchase for peak flavor and potency. Buying more than you will use in that time means accepting some degradation.
  • Variety: Buying a quarter lets you try different strains. Committing to a full ounce means staying with one strain for several weeks.
  • Legal possession limits: Many states cap personal possession at 1 ounce (28g) for adults, making larger purchases irrelevant at the personal use level.
  • Upfront cost: The savings per gram must be weighed against having more money tied up at once.

When a Quarter Is the Right Purchase

  • You are a light to moderate consumer (several times per week)
  • You want to try a new strain without a large investment
  • You want to maintain freshness and quality of your supply
  • You are shopping at a dispensary with good selection across multiple strains
  • Your consumption habits mean a quarter lasts 1 to 3 weeks

Frequently Asked Questions

These are the 10 most common questions about cannabis measurements, formatted for fast, direct answers.

1. How many grams is a quarter?
A quarter ounce contains exactly 7.0874 grams, universally rounded to 7 grams in cannabis culture and at legal dispensaries. It is one-fourth of a standard ounce (28.3495g) and is the most popular purchase size for cannabis consumers across the United States.
2. How many grams is a quarter pound?
A quarter pound equals 113.398 grams, typically written as 113.4 grams. It contains 4 ounces of cannabis, equivalent to 16 quarter-ounces. Quarter pound quantities are wholesale-level and exceed personal possession limits in most US states.
3. How many grams are in a half ounce?
A half ounce contains 14.1748 grams, rounded to 14 grams. It is exactly double a quarter ounce. Halves are a popular bulk purchase for regular consumers since they offer better per-gram value while remaining manageable in terms of freshness and possession limits.
4. How many grams is a quarter of an oz vs. a quarter of a pound?
A quarter of an oz = 7 grams. A quarter of a pound = 113.4 grams. The difference is exactly 16 times. In most dispensary conversations, "a quarter" means a quarter ounce (7g).
5. How much does a quarter of weed cost at a dispensary?
A quarter ounce typically costs $35 to $80 before taxes at licensed US dispensaries, depending on quality tier, strain type, THC content, and potency. After state and local taxes (which can add 15% to 40%), the out-of-pocket cost often ranges from $45 to $110+. Compare prices across dispensaries and look for member deals or daily specials to reduce your cost.
6. What is the smallest amount you can buy at a dispensary?
The smallest amount most dispensaries sell is 1 gram of flower, though some sell half-grams for pre-rolls or concentrates. The next step up is an eighth (3.5g), followed by a quarter (7g). For first-time visitors, buying a single gram or an eighth is a smart way to sample a strain before committing to a quarter ounce.
7. How do I know if I got the correct weight for my quarter?
Use a digital kitchen scale to verify. Place a container on the scale, press tare to zero it, then add your cannabis. A correct quarter will read between 7.0 and 7.1 grams. At licensed dispensaries, products are pre-weighed and sealed by law, but having your own scale at home is always useful for peace of mind and accurate dosing.
8. Why does a quarter sometimes look bigger or smaller than expected?
The visual volume of 7 grams of cannabis varies dramatically based on strain type and bud density. Dense, tightly-structured buds look smaller than airy buds of equal weight. Both weigh exactly 7 grams. This variation is completely normal and is not a sign of being shortchanged. It depends on how the cannabis flower was grown and processed.
9. How many joints can I roll from a quarter ounce?
A quarter ounce (7 grams) typically yields 7 to 14 standard joints, based on 0.5 to 1 gram per joint. Light users who roll 0.5g joints can get 14 joints. Heavier joints using 1g each yield 7. If you prefer blunts, which typically use 1 to 2 grams, expect 3 to 7 blunts from a quarter, making it a substantial amount for most consumption habits.
10. What is the best way to store a quarter ounce of cannabis?
Store your quarter in an airtight glass jar (a 4 oz mason jar works perfectly) in a cool, dark location. Maintain a humidity level of 59% to 63% RH using a small humidity control pack if possible. Avoid plastic bags, excessive heat, direct sunlight, and frequent opening. With proper storage, your quarter will remain potent and aromatic for 1 to 3 months or longer.

Final Summary: Cannabis Measurements at a Glance

Understanding cannabis quantities is an essential part of navigating the cannabis industry, whether you are a first-time buyer at a dispensary or a regular consumer optimizing your purchase strategy.
