How many grams in an ounce?


Before discussing pounds and ounces, let’s clarify how many grams are in an ounce of cannabis.


There are approximately 28 grams in one ounce of cannabis. This is a standard measurement used worldwide, making it easier for consumers to gauge the quantity of cannabis they are dealing with.


The exact number of grams in an ounce is 28.3495, but it’s often rounded down to 28, or to 28.35.


Cannabis weight conversions & how many ounces in a pound of weed


While the U.S. uses the imperial system (pounds) as a standard unit of weight, the country’s cannabis measurement system is done through the metric system (grams and ounces).


To simplify the process of converting cannabis weights, use the following conversions:


  • 1 pound (lb) = 16 ounces (oz)
  • 1 pound (lb) = 448 grams (g)
  • 1 ounce (oz) = 28 grams (g)
  • 14 grams (g) = 1/2 ounce (oz)
  • 7 grams (g) = 1/4 ounce (oz)
  • 3.5 grams (g) = 1/8 ounce (oz)


Understanding weed measurements


There are slang terms many use when talking about weights or amounts of cannabis flower. Here is some of the popular terminology associated with cannabis units of measurement:


  • 1 gram – This is typically the smallest amount of weed you can buy at a dispensary. It’s often referred to as a “dime sack” or “dime bag”. The price is usually around $10-$20 per gram.
  • 3.5 grams – Cannabis consumers often call this an “eighth” of weed. This is a normal purchase for those looking for a smaller amount of cannabis, but still looking to get good use out of their purchase. An eighth of weed can cost between $30-$60.
  • 7 grams – We call this a “quarter” or a quarter of an ounce of bud. A quarter is a solid amount of flower and can last for a bit. Quarters can cost anywhere between $40-$70.
  • 14 grams – A half ounce or “half zip” as some call it. You’re approaching a bulk marijuana purchase with this one. A half ounce can cost between $90-$140.
  • 28 grams – An ounce, “zip”, or “full”. This is a relatively large amount of weed. An ounce can cost anywhere from $140-$300.


How to weigh cannabis


Accurate measurements are essential in various aspects of the cannabis industry, from sales and distribution to cultivation and dosage. Here’s how to weigh cannabis correctly:


  1. Use a Digital Scale: A digital scale is the most accurate way to measure cannabis. Place your cannabis on the scale, and it will display the weight in ounces or grams. This is especially important for dispensaries and growers dealing with large quantities of cannabis.
  2. Tare Function: If you’re using a container to hold your cannabis, use the tare function on the scale to subtract the container’s weight, providing a precise measurement of the cannabis alone.
  3. Calibrate Your Scale: Periodically calibrate your scale to ensure it remains accurate. Calibration instructions can usually be found in the scale’s user manual.


How to determine cannabis weight without a scale


In some situations, you may find yourself without a scale but still needing to estimate the weight of your cannabis. Here’s a simple method:


  1. Visual comparison: Familiarize yourself with standard weight quantities by visually comparing your cannabis to common objects of known weight. For example, a gram of cannabis is roughly the size of a small grape, while an ounce is similar in weight to a slice of bread. This can be particularly useful for cannabis users in states like California and Colorado where recreational use is legal.
  2. Reference guides: Online reference guides often provide images and descriptions to help estimate cannabis weight. These guides can be especially helpful for beginners, whether they are using the metric system or the imperial system.
  3. Hand test: Place the cannabis in your hand and assess its weight relative to your experience. Over time, you’ll develop a sense of how much cannabis weighs based on touch. This is valuable for medical marijuana patients in states like New York where cannabis products are available.


Cannabis fractions: beyond ounces and pounds


While pounds and ounces are common measurements, the cannabis world also deals with fractions. Here are some of the most frequently encountered cannabis fractions:


  • Quarter of a Pound: A quarter of a pound is equivalent to 4 ounces or approximately 112 grams. This measurement is significant for growers and dispensaries when dealing with larger quantities.
  • Half-Pound: A half-pound consists of 8 ounces or around 224 grams. This measurement is crucial for growers and dispensaries managing larger inventories of cannabis products.


The importance of understanding cannabis weights


Whether you’re a cannabis connoisseur seeking precision in your purchases, a medical marijuana patient in need of the right amount for your condition, or a cultivator striving for accurate yields, understanding cannabis weights is crucial. In addition to facilitating legal compliance and informed decisions, knowledge of cannabis weights ensures you get the most out of your cannabis experience.

In the ever-evolving cannabis industry, where THC and CBD levels, terpenes, and cannabinoids are key factors, accurate measurements are the foundation for quality products and responsible consumption.




In conclusion, this comprehensive guide has unraveled the complexities of cannabis weight measurements, particularly the conversion from ounces to pounds. One pound of cannabis equals 16 ounces or 448 grams. Understanding these conversions, along with the basics of weighing cannabis, empowers enthusiasts and professionals alike to navigate the cannabis industry with confidence.


Whether you’re a cannabis enthusiast, cultivator, or industry professional, these insights into cannabis conversions and fractions will prove invaluable. Additionally, the ability to estimate cannabis weight without a scale ensures you’re never left guessing, no matter where you are in the world of cannabis.
