How Many Grams Are in an Ounce of Weed?

Weed weight measurement can be performed in different ways. You don’t need to buy a large volume at once to have a supply for several days or weeks. Many people know that one ounce of weed is a lot.

Only real pot lovers or those who want to stock up for a long time would buy it in such volume. I’ve done a lot of experimentation and weighing to answer the questions of how many grams in an ounce of weed and how much weed is enough for one take or a small supply.

How Many Grams Are There in an Ounce and the Way of Weighing


Before describing how many grams are in an ounce, I would like to describe metric measurements in more detail. Weed is usually measured in kilograms or grams, but both indicate too much weight for an average consumer. Even the size in pounds is irrelevant for weed since it is still a lot. Nobody would buy that amount for their consumption. Therefore, many are left with the question of what is an ounce of weed.

An ounce is 1/16 of a pound. You can purchase one ounce of the herb at any medical pharmacy, or less: half, quarter, or one-eighth. But how do you know how much marijuana or other weed you need?

How many grams are in an ounce of weed?

Now let’s move on to the question of what is an ounce of weed. Any metric calculator on the Internet will show that 1 ounce of weed (or any other material) equates to 28.35 grams. You probably won’t need one ounce of marijuana, as you often buy one second, one-fourth, or one-eighth of an ounce in official stores.

Please note that many vendors do not use decimal digits to calculate. Therefore, weights are rounded down. Any retailer in your area or pharmacist in the pharmacy will tell you that there are 28 grams of weeds in one ounce.

Let’s take a closer look at all the values for measuring the weight of grass:

  • 1 ounce = 8 eighths = 28 grams;
  • 0.5 ounces = 4 eighths = 14 grams;
  • 0.25 ounces = 2 eighths = 7 grams;
  • 0.125 ounce = 1 eighth ounce = 3.5 grams

Now you know for sure how many grams in an OZ are.

How to measure your weed

The above numbers mean nothing unless you measure the exact weight of the weed or marijuana. How do you know what 1 oz of weed or any other volume looks like? For measuring it, it is necessary to use a special scale. I will share a description and my own opinion on some of the popular weed and marijuana scales with you.

AccuWeight Mini Pocket – Accurate Scales for Measuring Ounce of Marijuana and Weed

The AccuWeight is a compact, battery-powered kitchen scale for weighing weeds or marijuana. Use them to measure up to 1000 grams in 0.1 gram increments. You can carry this small scale with you as it fits in any pocket.

Two AAA batteries are enough for the device to work for several months. If necessary, you can calibrate the values, as well as set the tare. You do not need to turn this scale on or off yourself, as it works automatically. This model is suitable for measuring weight in a variety of metric values, including grams and ounces.

  • Screen backlight;
  • Accuracy up to 0.1 grams;
  • Compact size.
  • No milligram measurement function.

Digital Pocket Scale – Ounce vs Gram Weed Measuring Device

Sometimes we need to measure a minimal weight of weed or marijuana. In such cases, I recommend using a special jewelry scale with measurements up to 0.01 grams.

The Digital Pocket Scale model is best suited for this. It can measure up to 100 grams of grass. It is a small device weighing 2.39 ounces that fits easily into a backpack or pocket. Two AAA batteries power the scales.

  • High measurement accuracy;
  • Measurement in grams and milligrams;
  • Powered by batteries.
  • Not a practical weighing surface.

AMIR – Сomfortable Kitchen Scale to Measure the Grams or Ounce of Weed

AMIR is a compact kitchen scale for weighing up to 500 grams in 0.01-gram increments. It is most convenient for measuring small amounts of weed or marijuana. I love that these scales have a special tray with sides.

It means you can weigh more grass than a flatbed scale. It is an efficient device convenient to store at home and not to be carried around. The model runs on two AAA batteries. Additional features include a display backlight, a choice of metric values ​​(for example, ounce or grams), and automatic shutdown.

  • Measurement up to 0.5 kilograms;
  • The presence of containers for weighing a large amount of grass;
  • Small error.
  • It is inconvenient to carry it in a pocket.

You will never know how much the weed weighs without using an accurate scale. Choose the model that is best for you, depending on the weighing conditions and the required weight.

But not everyone has the opportunity to use kitchen or jewelry scales right now. In that case, use one of the following methods:

  • Install a special weight measurement application on your smartphone. In the App Store or Play Market, there are free programs that work as a scale. Please install one of them. They work on a simple principle. You need to put weeds on your smartphone screen. The pressure on the sensor allows you to measure the exact weight with minimal error.
  • Use a paper scale and one dollar. Take any piece of paper or cardboard, and fold it in the form of a “W”. Central part of the folded paper is on a thin stick (eg, sushi). On both sides, you have to stick out the edges of the paper. On one side put a bill of one dollar (it weighs about 1 gram) and on the other side, a little weed. Get a balance to get about 1 gram of weed.
  • Use a clothes hanger. Clothing hangers have a balanced weight on both sides. Attach a thread on both sides, at the end of which tie two bags or disposable cups. In one container, put the weight which you know (for example, a bill of one dollar weighs one gram), and in the second container, a small amount of weed. Get a balance and get to know everything.

How do the measurements look?

Sometimes we need to know what a particular weight of weed or marijuana looks like. It’s needed when you can’t figure out how much quality product is necessary for you to relax. The herb itself is lightweight, so even half a gram is sometimes enough for a purchase. I decided to give simple and understandable examples for you to know what a particular weight of weed looks like.

The easiest way to understand the approximate volume of weed is to compare it to an object. For example, ounce vs gram weed look completely different. One gram is a small penny-sized bundle of weed. One gram of pot is sufficient for a large joint or a few little cigarettes. It is also influenced by the product’s quality since some grass is fluffy and of high quality, and some may contain garbage.

Half or a quarter of a gram will suffice for smoking one cigarette. But most often, marijuana lovers buy one-eighth of an ounce. We have already indicated the rules for measuring OZ of weed in grams. One-eighth of an ounce is approximately 3.5 grams. Imagine the diameter of the dial of any wristwatch. The heap of weed weighing 3.5 grams is about that size. It is enough to make about 5-7 cigarettes on your own. A quarter of an ounce will be twice as much in volume as one-eighth. It is approximately 7 grams of weed.

A half-ounce of weed in grams is about 14 grams and is comparable in volume to a matchbox or a lighter. But a whole ounce will take up as much space on the table as half a standard smartphone. These comparisons will help you visually assess the volume of different fractions of marijuana or weed.

The volume of weed largely depends not only on the weight and quality but also on the shape. You can buy ground weed or whole buds. Many recommend buying full buds to grind them yourself for smoking. Thus, you will visually assess the quality of the product.

For grinding, I usually use compact spice grinders, which I will discuss in more detail.

You may still have questions about why we need weed measurements and what to use for that. The answers can be found below.

Why should I measure my weed?

You should measure the weed upon purchase weight to know how much of the product you are buying. Usually, we buy a small weight of marijuana or weed in a few grams from pharmacies or dealers. You should not be fooled on the scales; otherwise, you will overpay.

When measuring weed, every milligram is essential, since even a small fraction of this product has great material value. You need to make sure you buy the exact weight down to the milligram. For example, if you are paying for 1 ounce, then the scale should be 28-28.3 grams. Usually, jewelry and kitchen scales are used for this.

How much should I purchase as a first-time user?

For the first time, a quarter of a gram will suffice. It is a small amount of weed, which is enough for one cigarette. If you are stocking up for a few days or weeks, then buy one-eighth or one-fourth ounce. It is the standard value for those who occasionally smoke weed or marijuana.

How much weed do I need to feel the effect?

The amount of herb needed to relax is not universal. Everyone reacts differently to weed. Moreover, weed and marijuana have different qualities and strengths. You can buy a quality product, and one ¼ gram homemade cigarette will be enough for you. And in some cases, it will take 1 gram to feel the effect.

Please note that this is a milled weed. You will need to grind it initially and remove debris from there. Only after that, the crushed herb must be weighed and rolled into a cigarette or smoked in a particular pipe.

Other factors also affect the amount of pot you need, such as a person’s physique and smoking weed experience.

What does an ounce of weed look like?

One ounce is a fairly large amount of marijuana or weed. Usually, such a massive weight is bought in bulk for a long time or for a group of friends. Imagine a pouch with the volume of a large fist. This is the approximate size that one ounce of weed or marijuana will have. Nobody walks down the street with such packages. Therefore, to begin with, it is worth buying smaller volumes.

Measure the Exact Weight of Weed

We rarely use a scale when buying weed or marijuana. Because of this, it is difficult to determine the exact weight, and sellers are deceiving customers. However, there are many ways to know the precise value of the weed you buy. For example, use a kitchen or jewelry scale with a measurement of up to 0.01 grams. The error of such devices does not exceed 0.003%, as indicated by the manufacturer. It can be done at home or at the time of sale.

Golden Bell 4 Piece

Sometimes I do not take the scales with me, to determine the volume of purchased weed visually. I know what one ounce, half an ounce, gram, and other amounts of marijuana look like. In this article, I described the marijuana gram chart to make it easier for you to compare ounces and grams.

Write in the comments, how do you determine the volume and weight of the weed? Do you use a scale or do you measure weight visually?
