How many Grams in an Ounce?

How heavy is an ounce? How many grams are in an ounce? If someone tells you they have a good deal on an eighth, what does that mean? We’ve all been there, trying to run numbers in our heads, wondering if we’re getting a good deal.

Fear not: Though measuring weed may seem sinister or complicated, it’s pretty simple with your good friend the metric system. Who knew you’d need to remember conversions from middle school to smoke a joint? Maybe pull out your textbook before tasking a toke of the good kush, though.

Weight is one of the most critical aspects of buying cannabis, and beginners may be wary of all the vocabulary, but the good news is that we’ve taken all the work out of figuring out conversions for you.

How to Weigh Weed

If you’re buying regulated cannabis from a dispensary, most of the time, the packaging on the kush will say how much the product weighs. Although, it’s never a bad idea to weigh it to make sure you’re getting your money’s worth or to practice using the scale.

Another thing to note is that dispensaries and sellers will often round up, so don’t expect the weight to be accurate right down to the decimal.

Here are the three best ways to weigh your weed:


It’s always smart to have a scale on hand, whether you’re a buyer, grower, or seller of cannabis. Plus, imagine how cool you’ll look while you’re weighing your weed before you roll a joint for your friends. If you’re just buying a scale for your personal use while buying weed, it’s best to find a compact digital scale you can carry around with you (We recommend this one).

Phone Apps

Some phones have scales on them that are relatively accurate. For example, IOS’s 3D touch makes it possible to use your iPhone as a scale. Of course, a more precise scale will benefit you more; however, it doesn’t get more convenient than pulling out your phone.

Make Your Own

Maybe you’re in a pinch and haven’t been able to buy your scale yet. There are other handy methods to weigh cannabis. They may require a few DIY skills, but they’re pretty easy to grasp.

Did you know that pennies weigh 2.5 grams? If you place a penny on one side of a ruler and your bud on the other side, you can see how much adds up to approximately 2.5 grams.

You can also use a hanger and two pieces of string to create a scale in a pinch. Simply tie the penny to one side of the hanger and your weed to the other side and hang it up.

Common Weights and Sayings

It’s a lot of vocab; we won’t lie. However, once you get used to saying measurements, it will be easy to know how much you need to buy. These weights are all using the metric system, and most of them use the gram as a baseline. We’ll start from the smallest amount and work our way up to the largest measurement.

Several determining factors, such as quality and strain, will affect the cost of these amounts.


A gram is the smallest unit of measurement for Mary Jane. A gram is usually the size of a single nugget or one small joint. If you’re hoping to test out a new strain or buy from a seller you’re not sure of yet, this is a great way to test out the product without being stuck with leftovers.

Cost: The average price for a gram of legal weed is $8-15


“Eighth” is short for “One-eighth of an ounce” (or 3½ grams). Usually, you can find a good deal when buying an eighth, and we would recommend this amount for casual smokers.

Cost: Average cost is $25-40


A quarter is equivalent to ¼ of an ounce, so if you’ve ever changed quarters, this is some easy math. It’s around 7 grams, so if you’re hoping to buy an amount that will last you a couple of months, this is the perfect amount for you.

Cost: Average cost is $50-75


Take a quarter and double it, and you end up with a half (half an ounce). This amount is about 14 grams.

Cost: Average cost is $100-150


Many states will have this amount as the legal maximum you can purchase at one time. An ounce is 28 grams or about 25-28 blunts. This law exists to stop the illegal selling of weed.

Cost: Average cost is $200-300


A pound of weed is a rare sight for most. Just to clarify how big a pound is, take an ounce and multiply it by 16. That’s about 450 grams. This amount is enough pot to last the average smoker for around a year.

Cost: You probably won’t be able to buy this amount legally.

What Effects Weight?

Don’t be fooled; not all weed is created equal. Some weed can be heavier or lighter, dependent on three factors: density, moisture, and strain. If you are concerned about whether you got a fair price, make sure to weigh your weed before buying it because looks can be deceiving.


Some nuggets are packed tighter than others, similar to how you can pack a bowl tighter or loose.


Depending on how fresh the marijuana is and other factors, it may still hold some moisture. The difference in moisture means the smaller-looking nuggets may be heavier than they seem based on how much water is in the leaf.


Believe it or not, certain strains weigh differently. Some strains may be more light and fluffy than others, while others are more condensed. Two nugs of different strains may look like the same amount but weigh differently.

In Summary…

So maybe it’s more math than you were hoping for, but overall, grams in an ounce is a simple concept. It may seem like you need a lot of equipment to weigh weed properly, but all you need is a scale or your phone and a little brainpower.

Take some time to brush up on all of the measurements and lingo before you go to buy some weed, and you’ll look like an expert. The perfect amount of weed will be different for every pothead.
