Cannabis is measured and sold by weight. That means that if you want to buy and puff like a seasoned weed veteran you have to know a little bit about how all this weighing and measuring works. Understanding how many ounces in a pound will help give you a more concrete idea of how far your bud will go.

## The Basics: How Many Ounces In A Pound?

In general, there are two main ways to measure weight. The metric system uses grams as the base unit, and the imperial system uses ounces and pounds.

Since we are trying to figure out how many ounces in a pound, we are dealing with imperial. Luckily, converting ounces to pounds is pretty straightforward.

There are 16 ounces in a pound. That’s all you really need to know. Done.

## Weed Measurements

In the U.S., weed is mostly sold in “eighths,” as in 1/8 of an ounce. Anytime you are trying to figure out how much weed you are dealing with, start with an eighth and work up from there. An eighth should last an average smoker somewhere around two to three weeks.

The next step up from an eighth is a quarter. A quarter is the same thing as 2 eighths, which equates to 1/4 of an ounce. Since a quarter is twice as much weed as an eighth, it should last you four to six weeks.

From there, you move up to a half. Equivalent to 4 eighths, a half is is a full 1/2 ounce of flower. At this point, you’re starting to get up into some big quantities of bud and you need to consider whether you can get through it all before it turns to dried out dust and goes bad.

If you have anything much more than a couple eighths laying around, you need to store it properly to be sure it stays fresh and potent.

The next rung on the cannabis ladder is a full ounce. This is the same thing as 8 eighths. If you’ve got a full ounce of bud at home, you should plan on staying high 24/7.

And finally, after an ounce, the next unit of weed measurement is a pound. Since there are 16 ounces in a pound, this is the same thing as 128 eighths. At this point, if you are buying weed by the pound, you are clearly not just trying to get high with your friends. You are either throwing an insanely huge weed party, or you are selling.

## Going Metric

There is still one more thing an expert weed smoker needs to know. Even though an eighth is the standard way to buy weed, and an eighth is dealing with ounces, the metric system is still an important part of the cannabis scene.

That’s because dispensaries often sell herb in grams, and when you weigh your weed on a scale, most people do it in grams.

This whole thing of going back and forth between imperial (eighths, ounces, and pounds) and metric (grams) can be a little bit of a headache. But with one basic conversion, you can figure things out pretty quickly.

Technically speaking, there are 3.54688 grams in 1/8 of an ounce. But to make things simpler, sellers just round it down to an even 3.5 grams.

When we use 3.5 grams = 1/8 ounce we can quickly calculate up from there. A quarter is 7 grams (3.5 x 2), a half is 14 grams (3.5 x 4), an ounce is 28 grams (3.5 x 8), and a pound is 448 grams (3.5 x 128).

Remember that these are not precise measurements. Instead, they are rounded down approximations. But this is how the world of weed works. As long as you know these basic conversions, you will be able to figure out exactly how much you are buying whether you’re picking up from your dealer or from your local dispensary.

## The Final Hit

If you want to know how many ounces in a pound of weed, the math is one thing. But what you really want to know is how much weed that is in terms of actual use.

One study found that when most people roll a joint they use somewhere around .66 grams of bud. Another one said the number was lower, down around .32 grams.

We decided to average the two out, and when we do that, we come up with roughly .5 grams of weed per joint. Let’s use that as our starting point.

- 1 eighth = 1/8 ounce = 7 average-sized joints
- 1 quarter = 2 eighths = 1/4 ounce = 14 average-sized joints
- 1 half = 4 eighths = 1/2 ounce = 28 average-sized joints
- 1 ounce = 8 eighths = 56 average-sized joints

At the end of the day, if you want to know how many ounces in a pound, there are really only two main things to keep in mind. The first one is that an eighth is 1/8 of an ounce. The second is that there are 16 ounces in a pound.

With these two bits of math in mind, you can quickly calculate out precisely how much weed is in an eighth, an ounce, and a pound. An eighth will get you through a couple weeks of average smoking. An ounce is eight times that much. And a pound is a full 128 times as much weed as an eighth.
