Gram. Eighth. Quarter. Half. Ounce.

If you’re not familiar with how cannabis is weighed, measured, and sold, all of those terms can feel like a huge question mark. It’s clear they’re units of measurement for weed — but what exactly do they all mean?

Breakdown of weed measurements

Let’s start with the smallest unit of measurement and work our way up.


A gram is defined as “metric unit of mass equal to one-thousandth of a kilogram.” A gram is a small unit of measurement, which makes it a solid choice for cannabis consumers who don’t want to purchase weed in small amounts. For example, if they’re looking to try a new strain or don’t consume cannabis frequently.

The rest of the units of measurement for cannabis have to do with ounces — either in full or a fraction.


An eighth is an eighth of an ounce — or 3 .5 grams of weed. The eighth is one of the most popular, if not the most popular, weight to sell cannabis. For many people, an eighth of weed is the perfect amount; it’s enough to feel like you have plenty of weed at your disposal, but not so much that you feel like you have too much weed and not enough time to consume it.

The next unit of measurement is a quarter. A quarter refers to a quarter of an ounce, and it weighs approximately 7 grams. Technically, a quarter weighs 7.0874 grams, but the industry standard is to round down to the nearest gram.

A half is a half-ounce of weed, which weighs 14 grams.


And a full ounce? An ounce weighs 28 grams.

When you’re purchasing weed in a dispensary, typically, the highest volume you can buy at any one time caps out at an ounce. But people who work within the cannabis industry, such as buyers and dispensary owners, can buy in larger quantities — including pounds and kilograms. One pound is made up of 16 ounces — which weighs in at a truly impressive 448 grams.

Here’s a quick reference chart of how weed is measured — and how much each measurement weighs in grams:

  • 1 eighth = ⅛-ounce = 3.5 grams
  • 1 quarter = ¼-ounce = 7 grams
  • 1 half = ½-ounce = 14 grams
  • 1 ounce = 28 grams
  • 1 pound = 16 ounces = 448 grams

How to make sure you’re getting what you pay for

When you purchase weed at the dispensary — whether you’re getting a single gram to test out a new grower or investing in a full ounce of your go-to strain — you want to make sure you’re getting what you paid for. And the only way to know for sure that your cannabis is the proper weight is to weigh it.

Your budtender should weigh out your cannabis in clear view; this way, you can see exactly how many grams are being weighed out — and how that corresponds to how much you asked for. If you get to the dispensary and can’t remember the gram conversions, just ask your budtender; he or she will be able to tell you how many grams are in an eighth, quarter, half, or ounce — and then can weigh out your weed to show you that the cannabis you’re taking home is the accurate weight.

In some states with adult-use cannabis laws, flower is required to come pre-packaged and was measured prior to arriving to the dispensary. If you still want to ensure that its the weight indicated on the packaged, you can weigh the flower with a scale at home.

Weed Scale – Why You Need It and Reviews of Top Brands

If you’re a smoker, you may have encountered a weed scale at some point along the line.

However, if you have not, you may have heard much about them or know that they might benefit you in some way.

If you’re wondering what a weed scale is, then it is much like it sounds like – a weed scale is used for weighing weed to a very precise degree to ensure that you have the exact amount of weed that you need.

While it’s easy to think that you can simply use any other scale that you already may have in your home, however, be careful!

A weed scale is unique because it is specifically programmed to be sensitive to the lighter weights of weed.

The normal scale that you use to weigh yourself or other household objects will not make the cut to measure precisely to the gram in the way that a weed scale can.

These handy little tools do a lot for weed smokers daily. Let’s explore some of the ways they help make the life of a smoker exponentially easier.

Benefits of Using a Weed Scale

Using a weed scale is an excellent way to be precise and exact when measuring how much weed that you have.

Whether when dealing or buying, it’s always good to have your very own weed scale to measure the amount of weed being exchanged to ensure that everyone involved in the bargain is being treated fairly.

Even if the person selling your weed to you measures it right in front of you, it’s always a good idea to have your own scale available to measure what you are being given.

This helps to ensure that you are not being shortchanged or ripped off at all along the way.

In addition, using a weed scale also helps you to measure exactly how much weed you have left, or measure up how much you are about to use.

For example, did you make the perfect batch of killer cannabutter and want to replicate it to a T?

Using a weed scale can help you to make sure you use precisely the same amount of marijuana in every batch so you yield the same result every single time.

While a weed scale may seem like an insanely simple thing, it has a lot to offer to any weed smoker.

The benefits are useful time and time again throughout your time of using weed, making a weed scale a simple but handy tool that any marijuana user should have in their toolbox.

Digital Weed Scale

Digital weed scales are the most popular type of weed scale marijuana users use today to measure the precise amount of weed they have.

These scales feature a digital screen that displays the exact measurement of precisely how much weed if on the surface of the scale.

This makes it easy to measure and read the right amount of weed, and adjust the amount on the scale until you are left with just the right amount of weed you were looking to measure out.

The screens and advanced measuring capabilities of digital weed scales make this possible in the easiest way imaginable.

Types of Weed Gram Scale

There are many different types of weed scales on the market for marijuana users to choose from.

However, with so many different options floating around the market, narrowing down the selection to the best viable option can be a real challenge.

Especially with so many stellar models to choose from that have served their owners well, finding the one that will work best for your needs is no simple feat.

Fortunately, if you keep a few simple factors in mind, you will be able to narrow down your choice to the best selection for you.

Let us help you narrow down your selection to the best scale for weed for your own unique needs.

Finding the Best Scale for Weed

To find the best scale for weed that is going to be best for your specific situation may not be the same as the best weed scale for someone else you may know who needs a scale to measure out amounts of marijuana.

Considering the following factors will help you to narrow down your selection to the proper choice for you:

Price: Weed scale price is certainly a factor you’ll want to consider if you’re shopping on a budget.
While you definitely want to spend enough to make sure that your scale will work well and last a reasonable amount of time, it’s up to you if you want to shell out any cash beyond that to get a fancier model.
A higher price range can get you extra bells and whistles or a sleeker, more attractive model. Depending on your budget, this is certainly a factor to keep in mind.

Functionality: What good is a weed scale if it doesn’t work well?
You want a weed scale that is sensitive to the weight of your herb and can precisely determine the weight of your weed and accurately calculate it to a T.

Appearance: Depending on the sort of setting you are intending to use your weed scale in, its appearance might be a significant factor to you.
If you’re selling weed to others, you might want that looks a bit sleeker, high-tech, and presentable.
However, if your weed scale will barely ever leave your nightstand, then this probably doesn’t matter nearly as much.

Durability: Some weed scales are more durable than others, so depending on what you are going to be putting it through, you may want one that can withstand a bit more wear and tear.
Ask yourself how often you’ll be using your scale and moving it around to determine how durable your weed scale needs to be to serve you well.

Warranty: You don’t want to find yourself replacing your brand-new weed scale just a few months or a year after you purchased it.
Many weed scales come backed with warranties to prove the company’s confidence and backing in the product they are selling.
Keep an eye out for the warranty offered on the weed scale you are considering, as this provides you with the reassurance that your scale will last at least that long or be eligible for repair or replacement.

Size: Depending on what situations you plan on using your weed scale in, or how often you plan on carrying it to different places with you, the size of your future weed scale might be of utmost importance.
Weed scales range in all different shapes and sizes, so if you are looking for a more portable version, it’s advisable to go for a compact option or pocket sized model.
