How Much Weed is an Eighth? Weed Measurements Explained

How Much Weed is an Eighth? Weed Measurements Explained

The lingo that surrounds purchasing cannabis can be confusing, especially if you’re new to buying weed. 

Eighths, quarters, dimes, half-packs — you need to know what’s what so you won’t get ripped off, and to make sure you understand how much each measurement actually gets you. Understanding weed measurements can also help you budget and plan for your needs.

Luckily, help is at hand. We’re here to give you the low down on the most common weed measurements used today. Read on to learn more…

Why Use Weights?

When it comes to weed, marijuana, or cannabis, names aside, looks can be deceiving.

That eighth you bought today may appear to be smaller than the gram you purchased last week. 

What gives!? 

This is because the density of buds and the way the weed has been broken down can’t be assessed by appearance alone.

By dealing in weight, both consumers and suppliers know exactly how much cannabis is being bought and sold. In other words, weed measurements such as an eight, quarter, ounce and more, keep everyone honest and add a welcomed standardization to an otherwise wild west of an industry.

Apart from the practical, it’s also essential for consumers to know how much they possess for legal reasons. For example, Oregon residents can legally carry an ounce of weed in public. However, possession of 1-2 ounces results in a violation charge, while anything above two ounces is considered a misdemeanor.

These are the most common weight measurements used by consumers and businesses within the cannabis industry.


A gram is generally the smallest amount of weed that can be bought legally. Even in the U.S. where the imperial weight system is used, dispensaries and suppliers use the metric unit of a gram.

The price for a gram is typically around $10, which has earned it the nickname of a dime. As the price for a gram varies, the term dime is gradually falling out of favor, especially in the legal marketplace. However, it’s a nickname that’s still around thanks to its deep roots in the black market trade.


An eighth means an eighth of an ounce (approximately 3.5 grams), the most common measurement that weed is sold in. Even in countries that use metric units, the weight of cannabis, apart from a gram, is often given as an imperial measurement.

Another term used to reference an eighth is a slice. The word derives from a pizza slice. Typically, pizzas are cut into eight slices, much like an ounce is split into eight.


A quarter refers to a quarter of an ounce. Other slang terms for a quarter include Q and quad.

Half Ounce

As you can probably guess, a half-ounce, or half-O, is exactly that — half an ounce of weed.


Again, the weight of an ounce is obvious. It’s also worth noting that an ounce is around 28 grams and has many alternative terms that consumers may encounter.

  • Zip: A throwback to when weed was distributed in Ziploc bags.
  • O-Z: From the abbreviation oz. for an ounce.
  • Pie: Pizza time anyone!
  • Onion: No other reason than it begins with an O.

Larger Weed Measurements

The majority of consumers will never purchase quantities greater than an ounce in the legalized market. Many states allow patients to possess larger amounts for medical reasons, but the weed is still packaged in ounce units.

However, for producers, retailers, and others working in the industry, cannabis is bought and sold in much larger quantities.

Quarter Pound

Also known as a quap or a QP, a quarter pound is equal to four ounces.

Half Pound

Weighing in at half a pound or eight ounces, a half-pound is also referred to as a half-pack or half-pounder.


A pound is a huge amount of weed, enough to keep the average consumer in product for a year! Weighing 16 ounces or approximately 453 grams, a pound is commonly called a pack or an elbow.


Although it’s usual to hear people describe a ‘ton of weed’, it’s not actually a recognized weight unit used in the cannabis trade. Even when talking about vast quantities of weed, they’re still discussed in hundreds and thousands of pounds.

Other Useful Weed Measurements

The legalization of weed has led to some slang and colloquial terms disappearing from the industry. However, it’s a good idea to be aware of them, just in case.

Half Gram

Half gram, or nickel, is an old term leftover from the black market era when consumers could purchase a smaller volume of weed for $5. As dispensaries tend to sell in grams, it’s unlikely you’ll encounter the half gram unless it’s in the form of pre-rolls.


Dub is another illicit market term used to describe $20 worth of weed. Weights varied from state to state but a dub typically contained 1-2 grams.

Final Thoughts on Weed Measurements

Hopefully, we’ve given you enough information and the jargon you need to head to the dispensary and order your weed with confidence. By understanding the lingo and how much cannabis you get with various standard industry measurements, you can better plan out your use, budget and make sure you’ll never run out of supply.
