If you ever plan on buying weed, you need to know how to answer the question: How much does an eighth of weed weigh? In fact, one of the most fundamental things you need to know is how weed is measured.
And one of the most important measurements you need to understand is an “eighth.” But what exactly is an eighth? And how much does an eighth of weed weigh? This guide will break it all down so you can navigate the world of weed like a pro.
What Is an Eighth?
For starters, you need to understand that in the U.S., weed measurements often bounce back and forth between imperial (ounces, pounds, etc.) and metric (grams, kilograms, etc.).
This can sometimes make it seem a bit more confusing than it really is. But don’t worry, there are only a few things you really need to know.
Let’s start at the beginning: What is an eighth? An eighth is 1/8 of an ounce. This is crucial because whether you’re buying from a dealer or a dispensary, an eighth is one of the most common units in which weed is packaged and sold.
Things get a little more complicated because you will sometimes hear people talk about weed in metric units. Typically, if that happens, it will be people talking about grams of weed.
Technically, there are 28.3495 grams in an ounce. Since an eighth is 1/8 of an ounce, you need to divide 28.3495 by 8 to see how many grams are in an eighth. When you do that, you’ll see that an eighth of weed is the same as 3.54688 grams of weed.
Since that’s such an awkward, clunky number, most sellers round it down to a nice even 3.5 grams. In this sense, weed measurements are a little bit different than a pure and strict measurement.
To put it simply, all you need to know is that there are 3.5 grams in an eighth. Using this simplified number also helps if you ever need to figure out how many grams are in an ounce of weed. If we’re saying there are 3.5 grams in an eighth, then that means there are 28 grams of herb in an ounce.
Here’s the full breakdown:
- An eighth = 1/8 ounce = 3.5 grams
- 8 eighths = 1 ounce = 28 grams
How Much Does an Eighth of Weed Weigh?
At this point, you should have a basic idea of what people mean when they’re talking about an eighth or a gram. But how much does an eighth of weed weigh if we were to really break it down in terms of actual weight?
The easiest way to get into all this is to compare an eighth to a pound since, for most people in the U.S., a pound is the most familiar unit of weight.
An eighth is the equivalent of 1/8 of an ounce. There are 16 ounces in one pound. So if we carry it all the way across, it looks like this:
- 8 eighths = 1 ounce
- 16 ounces = 1 pound
- 1 pound = 128 eighths
If you really want to get into all the details, you can translate all this over to metric as well. That conversion looks like this:
- An eighth = 3.5 grams
- 1 ounce = 8 eighths = 28 grams
- 1 pound = 16 ounces = 448 grams
Remember that these conversions aren’t technically precise. When it comes to measuring weed, most people just round things down to make it easier.
How Much Weed Is in an Eighth?
Understanding these basic units and conversions is great, but it still does not really tell you anything about how much weed you’re actually getting when you buy an eighth.
Obviously, the answer depends on whether you’re a light or heavy cannabis consumer. For example, if you’re a light or irregular smoker, then an eighth will go much further for you than it would for a heavy, everyday consumer.
But to give you a more concrete sense of how much weed is in an eighth, let’s think in terms of how many joints can be rolled with an eighth.
Taking them both together, the average joint weighs roughly 0.5 grams. That means that you should be able to get seven average-sized joints out of an eighth of weed.
The last way to break all this down is in terms of dollars and cents. Again, we can’t come up with precise figures for this, since prices change over time and vary based on where you’re at and what quality you’re buying.
With that said, you can expect a gram to cost somewhere around $12.00-$15.00. That means that an eighth of decent-quality herb will cost somewhere in the neighborhood of $40.00-$50.00.
Here’s the full breakdown:
- An eighth = 1/8 ounce = 7 joints = $40.00-$50.00
- A quarter = 1/4 ounce = 14 joints = $80.00-$100.00
- A half = 1/2 ounce = 28 joints = $160.00-$200.00
- An ounce = 8 eighths = 56 joints = $320.00-$400.00
In reality, though, prices will drop the more you purchase. In most places, an ounce of bud will probably run closer to the $230.00-$350.00 neighborhood.
Final Hit: How Much Does an Eighth of Weed Weigh
This guide covered all the ins and outs of the most basic weed measurements. But at the end of the day, an eighth is the most important thing you need to know about.
And the best way to figure out how much weed is in an eighth, and how long an eighth lasts you, is to burn through a few.
At that point, you will be able to give the best possible answer to the question: How much does an eighth of weed weigh?
Beyond that, your personal experience will teach you how long an eighth will last you, how much you need to buy at a time, and how often you need to reload.
