How Many Grams Are In An Ounce of Weed

The units of measurement of different sizes of weed can be somewhat confusing for beginners and seasoned users alike. From a gram to an 8th of weed, there’s a lot to learn in order to navigate the world of cannabis with ease. 

Understanding these distinct standard units of measuring marijuana is crucial for determining exactly how much product you are getting. Similarly, this knowledge is invaluable for marijuana companies. It helps business owners select ideal dispensary supplies for their products, such as the correct size for dispensary bags.

One of the most prevalent units for measuring cannabis is ounces. It’s the maximum amount of recreational marijuana a user can legally purchase in most states in the US that have legalized cannabis. Our comprehensive guide explores the most common units for measuring cannabis to uncover how many grams is an ounce of weed.

Understanding the Metric System

Before delving into cannabis measurements, it is essential to have a basic understanding of the metric system. This system is widely used and is the basis for most weight and measurement conversions.

The metric system primarily uses grams (g) as the unit for measuring mass. One gram is equal to one-thousandth of a kilogram (kg). Similarly, there are several other metric units for mass, such as milligrams (mg) and micrograms (µg). However, these units are not commonly used in the cannabis sector.

The Imperial System and Ounces

On the other hand, the Imperial system uses ounces (oz) as the primary unit of weight. This system is predominantly used in the United States, and an ounce is equal to approximately 28.35 grams. It is essential to note that there are two different types of ounces: avoirdupois ounces and troy ounces. Avoirdupois ounces are more commonly used, especially for measuring cannabis. Troy ounces, used primarily for precious metals, weigh slightly more at around 31.1 grams.

Converting Ounces to Grams

Now that we have a basic understanding of the two systems, we can answer the question: how many grams are in an ounce of weed? Using the avoirdupois system, one ounce of cannabis is equivalent to approximately 28.35 grams. This conversion is crucial for accurately measuring and purchasing cannabis, especially for users who are more familiar with the metric system.

Even so, there are still other measurement terms that may still require further explanation. For instance, what is a quarter of weed? When people talk of halves, quarters, or eighths when speaking about cannabis, they refer to portions of an ounce. So, if you want to know how many grams are in a half ounce, all you have to do is convert an ounce to grams and divide it by two.

Common Weight Measurements for Marijuana

Several weight measurements, transcending the imperial and metric systems, are used to determine the size of cannabis. Here are some of the most common ones:

Gram (g)

A gram is the base unit for measuring cannabis and is typically the smallest quantity available for purchase.

Eighth (1/8 oz)

Approximately 3.54 grams, this is a common quantity for personal use. They typically come in 8th bags, which have ideal dimensions for storing products of this size.

Quarter (1/4 oz)

Equivalent to about 7.09 grams, this is another popular option for personal consumption.

Half (1/2 oz)

This measurement amounts to roughly 14.18 grams and is suitable for moderate to heavy users or those sharing with friends.

Ounce (oz)

An ounce of cannabis weighs around 28.35 grams and is a standard quantity for bulk purchases or long-term use. Marijuana products weighing this much come in 1 ounce bags for weed.
