Marijuana Weight: Grams, Quarters, and Ounces. Oh my!

marijuana weight grams eighths quarters ounces

So, you like to smoke pot, but perhaps you’re beginning to feel like you need an advanced math degree to buy weed properly. There are grams, eighths, quarters, ounces, and the list keeps going. All of this may seem overwhelming at first, but marijuana weight conversions are actually pretty simple.


Grams are typically the smallest amount of weed that you would buy. Some people may sell you less; however, a gram is pretty standard if you’re looking to make a small purchase.

What exactly is a gram? Technically a gram is “the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice.” Please do not remember that last sentence.

Over time, you’ll be able to spot a gram pretty accurately. If you’re just starting out, or need to be precise then you can pick up a digital scale for less than $10.

Depending on your tolerance, a gram may last you a few smoke sessions. Alternatively, you can roll a gram into one blunt and blastoff to the moon.


An eighth = 3.5 grams.

Eighths are great for people who smoke somewhat regularly. An eighth refers to 1/8 of an ounce. You will almost always get a better price if you buy an eighth instead of a gram. In fact, price cuts are often given at each of the intervals discussed here.

Some people will also sell half-eighths, which should really be called a sixteenth. It’s 1.75 grams.


A quarter = 2 eighths = 7 grams

A quarter is often referred to as a ‘quad’. A quarter is 1/4 of an ounce. If you are buying a quarter then you are probably preparing to get pretty stoney. I commend this decision. Even if you don’t smoke everyday, buying a quarter will keep you from having to re-up all the time.

A half = 2 quarters = 4 eighths = 14 grams

A half refers to 1/2 of an ounce. See, I told you – these conversions really aren’t that tricky. At this point you’re throwing a party, and I want to be there.


An ounce = 4 quarters = 8 eighths = 28 grams

An ounce is often referred to as an O. It’s hard to describe the feeling of having an ounce of weed to yourself. The word ‘elated’ is pretty good, but still doesn’t do it justice.


A pound = 16 ounces = 64 quarters = 128 eighths = 448 grams

Let’s be honest. If you’re looking to buy a this much weight then you’re probably not smoking it all yourself (unless Snoop is reading this). At this point you probably should have already figured out these conversions.

You can also buy quarter pounds, half-pounds, etc. Again, by this point you should have this thing figured out.

If you’re using the metric system (we all should be, but what can you do, right?) you’re going to be using kilos, or kilograms.

A kilogram = 1000 grams

Like I mentioned earlier, if you’re new to this, and aren’t familiar with what each amount should look like then I highly recommend picking up a digital scale. There are a few visual guides, but different buds have different densities so the same weight doesn’t necessarily mean it’s the same volume. Seriously, just bite the bullet and get a scale.
