How Many Ounces to a Pound of Cannabis?

Marijuana is usually measured and sold by its weight and if you are like me, you may wonder how many ounces are to a pound of cannabis.

That is why if you are new, or even if you have smoked some rolls before, you need to know the basics to estimate your purchases and your intake.

If you understand how many ounces there are in a pound, you will have a better idea of how far your bud will last.

Ounces to Pound

Generally speaking, there are two ways to measure mass.
We have the metric system that uses grams as the standard unit. The imperial system, on the other hand, uses ounces and pounds.

Since our goal is to figure out the conversion of ounces to pounds, we’ll be using the imperial system. Good thing, this process can be pretty straightforward.

All you need to know is that there are sixteen ounces in one pound. Well, a pound is a lot of cannabis indeed and is often referred to as lots, heaps or even ‘shitloads’ depending on where you live.

Measurement of Cannabis

In the United States, cannabis is usually sold in “eighths” or 1/8 of an ounce.

Every time you work out how much cannabis you are buying, start with an eighth and work up from there.
An eighth usually lasts somewhere around 2-3 weeks for the average smokers.

After the eighth, there is the quarter. If you haven’t figured it out yet, two eighths are equal to one quarter, and a quarter could last you 4-6 weeks.

The next step from a quarter is the half. Exactly equal to four eighths, two quarters, and is a full hall of a flower.
If you are not planning to share your stash, a half might be much for a single smoker, as if not consumed in the best before date, it might just dry out and go bad. If you have more than what you need, you can store them properly to keep your beloved herbs potent and fresh.

Next up is a full ounce. Precisely equivalent to eight eighths, four quarters, two halves.
Finally, after an ounce is the pound. Since we mentioned earlier that there are sixteen ounces in a pound, one pound is equal to 128 eighths.

At this point, you are obviously planning a huge party to get high with your friends or you are planning to resell it. Just make sure that you consume or sell it before it gets ‘too old’ and loses its potency.

Measuring in Metric

If you really want to be more savvy and smarter in your purchases and consumption you also need to learn how to measure in the metric system. It is because most of the dispensaries do sell and measure cannabis in grams.

Converting back and forth from imperial to metric can be a bit confusing. But we have a simple basic conversion guide to help you figure things out much quicker.

Technically, there are 3.54688 grams in an eighth of an ounce. Usually, sellers round it down to 3.5 grams for easier transactions.

If 3.5 grams = 1/8 ounce, then:
7 grams = one quarter
14 grams = one half
28 grams = one ounce
448 grams = one pound

Keep in mind that these are not accurate measurements, rather, they are just rounded down so they are easier to work with. As long as you keep these numbers and conversions in mind, it will be easier for you to keep track of how much you buy from your dispensaries or local dealers.

The Computation that Matters

Knowing the conversions and numbers is one thing, but what you need to know more about is how much cannabis that is in terms of actual use.

A study found out that most people usually use more or less .66 grams of bud to roll a joint. Another study said that it is much lower, saying it is only .32 grams. If we average the two given figures, we get somewhere around .5 grams of marijuana per joint.

With that variable, we can solve that:

An eighth = 1/8 ounce = 7 average-sized joints
A quarter = two eighths = 1/4 ounce = 14 average-sized joints
A half = four eighths = 1/2 ounce = 28 average-sized joints
An ounce = eight eighths = 56 average-sized joints

In conclusion, if you want to work out these simple conversions, you just need to keep two main things in mind:

1) An eighth is 1/8 of an ounce
2) There are 16 ounces in a pound

With these two learned by heart, you can easily and accurately figure out how much you are buying and consuming for you to be able to budget or schedule your sessions.
