Whether you're a dispensary owner or customer, knowing how many ounces are in a pound of weed can help you score the best value for cannabis flower, shake, or trim.

Knowing the common weed measurements ensures you buy the right amount for your needs. Knowing how to convert ounces to pounds and pounds to ounces is also helpful.

Buying in bulk often gives cannabis businesses a better bang for their buck compared to consistently and individually buying one gram, eighths, quarter ounces, half ounces, or even ounces of cannabis at a time.

Knowing the amount of weed you’re getting in your purchase can help save you time and money in the long-run. That means you can spend less time driving to the dispensary or paying delivery fees and more time enjoying your weed. Let’s find out how many ounces in a pound of marijuana.

Mass vs. Weight – What Is the Difference?

Let's start with the basics. Before we discuss how to convert pounds to ounces or ounces to pounds, we will cover the difference between weight and mass. Many people use these two terms interchangeably, but they mean different things.

Mass refers to the quantity of matter in an object. Mass is commonly measured in kilograms and grams.

Weight refers to the interaction between an object and gravity. It is the force of gravity exerted on the mass of an object.

In other words, the weight of a mass is caused by gravity.

Here’s a formula to remember the difference between mass and weight.

Weight = Mass x Acceleration Due to Gravity

Although the mass of an object remains a constant throughout, its weight varies from place to place. For example, that means you will have the same mass on Earth as you do on the moon.

On Earth, gravity can change by location due to several factors, including seasons, topography, and other environmental conditions. For example, the gravity on Earth is weaker at the equator due to centrifugal forces created by the Earth’s rotation. Gravity is also weaker at higher altitudes, since it is further from the planet’s center.

In short, you can weigh differently based on your location.

In an extreme example, your weight on the moon would be substantially less because the moon's gravity exerts far less force than on Earth. For example, if you weighed 175 lbs on Earth, you would weigh 28.93 lbs on the moon.

On Earth, the average surface gravity is 9.8 meters per second per second. On the moon, the average surface gravity is about 1.6 meters per second per second.

Summary – Mass is an inherent characteristic of matter. No matter where you are, it does not change. Weight can vary depending on the effect of gravity. In an environment without gravity, an object’s weight can be zero, but its mass does not change.

American vs. Standard Mass Measurements

In the United States, the standard units of weight are ounces, pounds, and tons, all part of the U.S.’s customary system of weight.

Tip: Do not confuse the U.S. customary system of weight with the British imperial system. Although they both use the same names of the units, their sizes can vary significantly.

Generally, small amounts of mass such as mail and packages are weighed in ounces. Medium amounts such as your body weight are measured in pounds. Large objects such as cars or trucks are measured in tons. While you can use any customary measurement unit to show the weight of an object, this is the most common way to use ounces, pounds, and tons.

You can easily convert between these units of measurement. For a better perspective on the relationship between each unit weight, here is a conversion:

  • 16 ounces = 1 pound
  • 2,000 pound = 1 ton
  • 907 kg = 1 ton

The metric system, used internationally, measures dry weight in grams (g), kilograms (kg), and tonnes (t). In some American product labels, U.S. customary units (ounces and pounds) may be listed alongside metric units (grams). Metric units are also commonly used by American companies during the manufacturing and distribution process.

What Is an Ounce?

According to Merriam-Webster, an ounce, abbreviated as oz., is defined as “a unit of weight equal to 1/12 troy pound” or “1/16 avoirdupois pound.”

But, what the heck is a troy and avoirdupois pound?

Troy weight is “a system of weight used mainly for precious metals and gems.” A troy ounce is equal to 31.10348 grams and often abbreviated as “oz t” or “t oz.” A troy ounce is equal to 0.0833 troy pounds.

An avoirdupois ounce measurement of weight is based on the pound of 16 ounces. In the U.S., the avoirdupois unit, measured in ounces and pounds, is standard. An avoirdupois ounce is equal to 0.0625 pounds or 28.35 grams, slightly lower than the troy ounce.

Summary: An avoirdupois ounce is equal to 1/16 of an avoirdupois pound. A troy ounce, used to weigh precious metals, equals 1/12 of a troy pound.

What Is a Pound?

According to Merriam-Webster, a pound, abbreviated as lb., is defined as “a unit (of mass and weight) now in general use among English-speaking peoples equal to 16 avoirdupois ounces or 7,000 grains or 0.4536 kilograms.”

Generally, one pound is 16 ounces.

What Is A Pound Of Weed?

The cannabis industry has many common units of measurements for whole-flower products (flower, trim, shake) starting at one gram and going up to a full ounce for dispensary customers. Cannabis customers can buy weed in eighth (3.5 grams), quarter (7 grams), half (14 grams), and full ounces (28 grams).

A pound (abbreviated as lb.) is a unit of weight used to measure cannabis and is typically used in the United States. Most other countries use the metric system (gram, kilogram, and tonne).

Who Buys Pounds Of Weed?

The most common amount of cannabis bought by customers is 3.5 grams (one-eighth of an ounce). Cannabis brands commonly sell flower, trim, and shake in grams and ounces. Cannabis consumers can also buy cannabis in 7 (one-quarter of an ounce), 14 (one-half of an ounce), and 28 (1 oz) gram varieties.

Cannabis consumers aren’t legally allowed to buy pounds of cannabis flower at one time. While many states have legalized cannabis for medical and/or recreational use, each one has distinct laws.

Each state has different medical and recreational cannabis possession and purchasing limits. For instance, California allows recreational users to buy up to one ounce of cannabis per day, while medical users can buy up to eight ounces of cannabis daily.

Depending on the purchasing limits in the state, consumers may be able to buy multiple ounces of weed every day and slowly accumulate a pound of weed for a number of reasons. For example, some medical users may need stronger and more consistent relief and require more cannabis flower to find that relief.

Cannabis consumers who buy pounds of weed may be stocking up to cook or bake with cannabis, although growing cannabis at home ca be more out effective in the long run (if your state allows home cultivation). 

Edibles often require high volumes of fresh cannabis to make an infusion. Making cannabis concentrates like shatter or bubble hash also requires high amounts of cannabis material to extract the buds’ cannabinoids and terpenes.

conversion chart, how many ounces in a pound of weed

Dispensary owners, delivery service operators, cannabis extraction companies, and other commercial cannabis processors are the only ones buying up pounds of cannabis at a time to keep costs down for them and for their customers.

Dispensaries buy up pounds of their best-selling marijuana strains to keep it ready on shelves and avoid selling out of their most popular products.

Cannabis extraction companies must buy in bulk to fill a large biomass tank where solvents (ethanol, CO2, butane) strip the cannabinoids and terpenes to produce large volumes of crude extract, which can then be processed into a variety of extracts like live resin, crumble, budder, isolates, distillates, and more.

How Many Ounces In A Pound Of Weed?

how many ounces in a pound?

For consumers looking to buy a pound of weed, you’re going to have to make multiple trips to the dispensary on different days (if your state allows it). Cannabis customers can’t just buy a full ounce due to varying purchasing limits on cannabis by state.

When buying cannabis from a dispensary or delivery service, you’re more than likely going to be buying ounces of weed or fractions of ounces such as eighths (3.5 grams), quarters (7 grams), or halves (14 grams).

Cannabis pounds are never sold at one time due to state regulations that limit how much cannabis medical and recreational consumers can buy.

If you’re wondering how many ounces is a pound of weed, the answer is 16 ounces or 448 grams. That means that if you buy a single ounce of weed in a dispensary, you’re buying 1/16 of a pound.

1/16 may seem like a small amount relative to one pound of weed but in reality, an ounce of cannabis can last weeks or months (depending on the amount used and frequency of use) and can retain its potency and aroma for longer if stored properly in a dark, cool, and dry space in an airtight and UV-protected container.

Technically, there are 28.3495 grams in an ounce of weed and 453.592 grams in a pound of weed. However, dispensaries have long been rounding down to 28 grams when selling ounces for simpler transactions.

Using these rounded-down measurements allows cannabis retailers to sell half an ounce (14 grams), a quarter (7 grams), or the popular eighth (3.5 grams) at even measurements without having to measure accurately down to the fourth decimal place.

An eighth of cannabis is actually 3.54369039 grams, but that’s hard to get just right with conventional scales. Over time, the rounded-down approximations can add up, but these industry standards are here to stay to streamline the shopping process.

If you want to know how many ounces or grams are in a quarter or half pound of weed, just divide by 4 or 2, respectively. A quarter pound of weed is four ounces or 112 grams. A half pound of weed is eight ounces or 224 grams.

If you want to buy two pounds of weed, that would be 32 ounces. Three pounds of cannabis would be 48 ounces. Four pounds of weed is 64 ounces and so on.

Not everyone buys up a full ounce on every dispensary visit. Weed is typically sold as fractions of an ounce at dispensaries.

The three most common ounce fractions bought at pot shops are eighths (one-eighth of an ounce or 3.5 grams), quarters (one-quarter of an ounce or 7 grams), and halves (one-half of an ounce or 14 grams).

Infrequent users may stick with single gram options or pre-filled joints. Heavy and daily users are better off buying in bulk to save money and time.

Now, let’s break down what fraction of a pound are eighths, quarters, and halves. An eighth (3.5 grams) of cannabis is 1/128 of a pound. A quarter of weed (7 grams) is 1/64 of a pound. A half of weed (14 grams) is 1/32 of a pound.

These fractions of a pound are not very easy-to-remember, which is why dispensaries typically deal in fractions of ounces as units of measurements, which are easier for customers to remember and work with.

Dispensary owners and other cannabis businesses typically don’t use the same units of measurements as cannabis consumers when buying or processing weed.

Instead, dispensary owners and processors buy up pounds of weed at a time to meet the high demand for the most popular cannabis product: flower. Instead of buying up 240 ounces of cannabis, a business owner would simply say they’re buying 15 pounds of cannabis.

How To Weigh A Pound Of Weed?

a scale with cannabis flower on it

Cannabis consumers or business owners with a pound of weed on their hands can double-check that their weight is correct by weighing the product with a scale. Eye-balling the marijuana to weight it will not yield accurate measurements.

Cannabis flower buds vary in density, size, and shape. For example, dense indica buds can take up less space than wispy sativa flowers. Indica flowers are known for being smaller and denser than sativa buds that can be long, slender, and airy. Hybrid strain density, size, and shape are determined by its genetics.

A dependable and functioning weed scale can ensure you accurately measure out the right dose of cannabis or use the right amount of weed when making edibles. Using correct measurements when cooking with weed ensures you consume the right amount without feeling any adverse effects that can occur due to overconsumption.

Picking the right scale for measuring a pound of weed requires users to consider the capacity of the scale and its resolution. The resolution means how accurately the scale can measure an object.

Most small, digital scales can measure with a tenth of a gram accuracy (0.1 gram). Smaller scales are ideal for measuring eights (3.5 grams) and other fractions of an ounce. For most users, a small digital scale can help them measure out their personal stash.

For a larger volume of weed, a larger scale is needed. Larger scales usually have better resolutions than smaller ones. Large scales can measure within one-hundredth of a gram (0.01 gram). Larger scales are commonly used by cannabis companies.

Now, you may be wondering: why do larger scales have better measurement accuracy than smaller scales? Larger scales can measure down to 0.01 gram because of the quality of their load cells. Load cells measure the mechanical force of an object.

Digital scales convert the force of weight of the object into electrical signals. The quality and number of load cells on a bigger scale is meant to maintain its accuracy, even when weighing larger quantities.

Larger scales also have bigger platforms capable of handling a high volume of weed at once compared to the smaller platforms of small scales. Users may use a container with high sides to measure the weight of the weed vertically to avoid spilling it over the platform.

A gallon container should be enough to measure up to a couple of pounds of cannabis flower buds. Users should make sure to zero out the weight of the container before adding the weed into it to not include its weight in the final measurement.

When weighing the cannabis flower on the scale, users should account for the weight of the packaging and subtract that from the total weight. Removing the cannabis front the packaging ensures users get an accurate measurement.

Also, users should make sure the weight scale is properly calibrated to get accurate results. Weight scales have multiple weight units including grams, ounces, and more.

Finally, consider readability of the scale, which is the smallest increment that a scale can display.

Can You Weigh Weed Without a Scale?

Measuring the amount of weed you have by eye is not effective. Even if you’ve been dealing with large quantities of weed for decades, there’s absolutely no way to weigh cannabis by eye. You may get close to your goal weight when measuring by eye but be off by several grams or ounces.

It’s difficult to accurately measure the weight of any amount of cannabis without a scale, including one gram of weed, let alone an ounce or a pound of weed.

One reason measuring by eye is difficult is because of varying densities and structures of weedflower, shake, and trim. Looking at bud size alone isn’t enough.

Some long and airy sativa buds may look big, but can weigh less than a dense indica popcorn bud that looks smaller. In addition, some shake can have finer consistency or larger chunks of bud.

Most cannabis from licensed retailers comes pre-packaged in certain amounts. If you or someone else weighs weed without a scale, just know you run the risk of over or underestimating the actual weight.

How Many Fluid Ounces Are In a Pound?

Fluid ounces measure the volume of an ingredient or material such as a liquid. The number of fluid ounces in a liquid will depend on its density. For example, honey is denser than water. Density refers to the level of compactness of a substance or object.

Here is a list of the density of common fluids at 68º F (20º C) and 1 atm (atmospheric pressure).

FluidDensity (g/cm3)
Water0.99820
Gasoline0.66-0.69
Ethyl alcohol0.791
Olive oil0.9
Milk1.028-1.035
Sea water1.03

Do not mix up fluid ounces for standard ounces. Standard ounces are measurements used to weight dry ingredients, such as sugar or flour. Fluid ounces measure the volume, not the weight, of liquid ingredients, such as milk or water. For this reason, 16 fluid ounces do not equal one pound.

If you want to convert a fluid ounce, abbreviated as fl. oz., measurement into a pound measurement, there’s an easy way to do it. Divide the volume multiplied by the density of the liquid by 15.337783.
