Weed Measurements – Gram, Eight, Quarter, Ounce And Pound Of Weed

Understanding marijuana measurements can be downright confusing. Thankfully, once you learn it the first time, it’s easy to remember. Seeing that knowing the standard measurements for purchasing marijuana is important, I will explain it. This article explains every measurement, from a single gram to pounds of weed.

Why does this matter?

I realize the focus of my blog is growing marijuana for personal consumption, but I also recognize that sometimes you need to know exactly how much you have. This is especially the case in places that limit how much you can have. Even if you are not planning to grow it, if you plan to buy it, you need to know how it’s measured.


There is a weed measurement system, which follows the metric system, and this article serves as your handy guide. I plan to clear up the differences between marijuana in terms of grams, eighths, quarters, halves, ounces, pounds, and kilos.

I can’t say this enough:

The world of marijuana has an entirely new vocabulary that comes with it, so newcomers are often confused. Don’t be discouraged! There are plenty of newcomers now that the legalization movement is well underway, and this means that you are not the only one looking for answers.

Some people can eye these things, but if you are new to this, it’s a good idea to buy a scale. That way you can weigh weed and know for sure.

Here’s the deal:

Size is different than weight. A fat juicy bud may look like it weighs half of a gram, but if it’s fluffy rather than dense, it probably does not.  On the other hand, I’ve grown some tiny, dense buds that would knock you out cold. My point is, without a scale, it is easy to confuse size for weight when you do not use a scale.

MetricsWeed measurements
1 gram1 gram
3.5 grams ⅛ of an ounce (referred to as an eighth)
7 grams ¼ of an ounce (referred to as a quarter)
14 grams ½ of an ounce
20 grams 1 ounce (referred to simply as an ounce)
448 grams 1 pound (referred to as a pound)

How to Measure a Gram of Weed or “Dime Bag”

A gram is the typical unit for people looking to buy a small amount of weed, and it generally doesn’t get any lower than one gram.

For most people, one gram of weed will last them a couple rounds of smoking, some a few days or weeks depending on your intake level. Some prefer to put the entire gram into one blunt, however, to achieve a more intense high.

How Many Grams in an Eighth?

Simply put, an eighth of weed is the same as one-eighth of an ounce in weight. While this may be true, I should also point out that marijuana weight doesn’t quite follow the rules of other weights.

An ounce of marijuana is 28 grams. A real ounce, however, is 28.375 grams. So technically speaking, an eighth should weigh 3.54688 grams — but in reality, it only is 3.5 grams.


Why is it done this way?

This isn’t to rip you off but rather a simpler way of measuring using grams (since only the more sophisticated scales measure hundredths of a gram).

    In general, buying weed in eighths is going to be a better deal than if you bought it in grams. It’s also important to note that half-eighths are also a common measurement for weed dealers and buyers, weighing in at 1.75 grams.

    How Many Grams in a Quarter?

    A quarter of weed is the equivalent of two of the above-mentioned eighths, and it consequently weighs around 7 grams.

    Quarter of weed

    Quarters can also go by the name of ‘quad,’ and it is generally bought by people looking for an intense high or a long-term solution to buying their weed less often. People looking to share will also purchase a quarter of weed.

    How to Measure One-Half of Weed

    One-half of weed refers to a half of an ounce, which, as logic dictates, is twice the amount of two quarters. If you want to get even more in-depth with it, it is also the equivalent of four marijuana eighths, which is the same as the weight of 14 grams. This is a lot of weed, only the biggest parties or regular medical users might need that much.


    How to Measure an Ounce of Weed

    An ounce of weed is two halves, or four quarters, or eight eighths. It measures up to 28 grams and is often called by its first letter, ‘O.’ Buying an ounce is a huge amount of weed.


    Finding this much at one time legally is rare. It’s also the legal limit in many recreational states. So, if you do have that much, it will provide you and all of your friends with enough for a long while.

    How to Measure Pounds and Kilograms of Weed

    As is normal in the American Imperial System of measurement, one pound of marijuana is equal to sixteen ounces. This is the equivalent of 64 quarters, 128 eighths, or 448 grams. At any rate, it’s a gigantic amount of weed. This is probably not the size anyone intending to smoke is going to buy, so they probably are already aware of how the measurements work

    In case you are not familiar with the Metric System of measurement, it’s important to note that one kilo (or kilogram) equals 1000 grams. It is the largest unit of measure in which you might buy weed (and is more than twice the weight of one pound). For this reason, it is typically related to traffickers. Simply put, amateurs or newbies wouldn’t be buying a kilo of weed.
