A Brief About Weed Measurements

Let’s broaden a scope a little bit and understand where the ounce measurement stems from. Just like with anything else, weed can be measured in pounds and kilos. But a kilo or a pound of weed is a lot of weed. However, consumers will usually not purchase such large amounts. One thing about the Kilo and the pound is that they can be related to the ounce.

What is an ounce in general terms?

Grams in an Ounce of Weed

An ounce can be described as one-sixteenth of a pound. That means it is one part of a pound that has been divided into sixteen equal parts. Dispensaries sell weed in terms of ounces. You can buy a half, a quarter, or even an eighth ounce as well. These measurements should begin to give you a feel of just how precious a commodity weed is. 

Let’s dig deeper. 

According to WeedNews the ounce is arguably the best way of measuring your favorite strain of weed flower. When you visit your weed dispensary, you will find packages of an eight, quarter, or half an ounce. Apart from the ounce and its variations, you can also buy in grams. The gram is a smaller unit of measuring weed as compared to the ounce. 

The gram is one-thousandth of a kilogram. Picture a kilo of weed divided into one thousand equal parts. 

Why would anyone prefer buying weed in the gram than ounce?

There are many reasons why a cannabis consumer would want to purchase small amounts such as the gram. First, we all know that weed is an expensive commodity. Not everyone has the money to purchase weed in ounces. Also, personal consumption of weed involves very minute amounts. One stick of weed roll usually has a one to two grams of weed. 

Measuring weed in small amounts also allows people to mix strains. You might want to create a blend of your favorite flower strains. It might be expensive to buy an ounce of each strain in order to get your perfect blend. Also, the small amounts are quite ideal when you want to try out a new strain. You do not want to purchase a large amount of a strain that you will most likely not like. 

The bottom line is; the gram is the ideal measurement for infrequent weed consumers. If you just want a small piece that you could occasionally pull out and get your fix, the gram will be quite convenient. As mentioned earlier, the ounce is ideal for frequent consumers, who have to ensure they have enough stock for whenever they need to get their fix. 

At this juncture, you should have a clearer picture of how weed is measured and the size of the various weed amounts sold in a dispensary. 

Now we can get back to our question. How many grams are there in an ounce of weed? We have already established the relationship between grams and ounces as far as weed measurement is concerned. Finding out how many grams are there in an ounce is not an issue of simple mathematics.

Realistically, it is not possible to measure 0.001 gram of weed. In most instances, the number is usually rounded off to the nearest whole number during a sale. As such, an ounce of weed has 28 grams. 

Let’s do a bit of math and find out the “28” comes from. 

We’ve already established that an ounce is one-sixteenth of a pound. Also, one pound is equivalent to 0.453592 kilos. 

If, therefore, follows that an ounce is equivalent 0.453592 divided by 16. It also means that one ounce is equivalent to 0.0283495 kilos. 

One kilo has 1000 grams. Some 0.0283495 kilos have 28.3495 grams. 


One ounce = 28.3495 grams

How many grams in a half ounce?  How many grams in a quarter? How many grams in an eighth? All these are variations of the ounce. 

It should be easy to establish how many grams are in a half-ounce, quarter-ounce, or one-eight ounce of weed. One eighth is going to be 28 divided by 8, which is 3.5. That means one-eighth of has 3.5 grams of weed. We’ve summarized all these measurements in the list below.

How Do You Know Your Ounce of Weed Had 28 Grams?

So, how do you then tell that the package you’ve been sold has the correct number of grams? Do you have to walk into the dispensary with a weighing scale? That would not be necessary. There are a number of ways you can tell whether you are getting the right grams in your ounce. 

First, is from the look of it. This one is for those who are experienced and have bought their strain for quite a while. If you have bought an ounce a couple of times, it should be easy to determine whether it is in the right amount just by eyeballing it. Keep in mind that different flower strains have different densities. As such, if you are buying a different strain from the one you are used to buying, eyeballing it is most likely not the most ideal way of determining whether you get the right amount. 

It, therefore, follows that the only sure way of determining whether you are getting the right number of grams is by using a scale. Most dispensaries have weighing scales. You should insist on buying from a dispensary that has a weighing scale and can weigh the weed for you. It has become a standard of the industry that your budtender must weigh your flower in your presence before they package it for you. It is the only way of ensuring nobody is shortchange. Even a quarter of a gram is very significant in the weed world. 

There is no harm in having a scale of your own back at home, especially if you are buying your weed online. Ensure you get the right scale. There are quite a number of weighing scales meant to weight small amounts in the market nowadays.

Some people use apps on their smartphones to measure their weed. Apparently, the app can weight whatever is placed on the phone’s screen. While it happens, these apps cannot in way be accurate in the way that an actual scale is. If you are hell-bent on ensuring your weed is measured accurately to the last fraction of a gram, the smartphone apps will not do the trick for you. 


The weed market is growing rapidly. Bigger weed farms are being established, and weed is going to become a multi-billion industry very soon if it already isn’t. The weed growing industry has brought life to many other industries. For instructing, there has been a surge in the demand for grow lights because of expanding weed farms. The grow lights provide the optimal conditions for growing weed.

It is important that you get weed of good quality and you get it in the right amount. As mentioned earlier, weed is an expensive commodity. Every gram has a significant cost. As such, the measurements are a very important factor. Fortunately, the measurements of weed are not in any complicated. That’s quite evident from the conversations we’ve had above.
