How Many Grams Are In An Ounce of Cannabis?

Stoners are often regarded as airheads only concerned with smoking sweet ganja and finding a sweeter snack shortly after, but the truth is, not even Albert Einstein could calculate weights faster than a dedicated stoner trying to reach an arrangement with his dealer. The truth is, delta 10 vape carts have made us lazy. We don't need to weigh our stash anymore.

Whether you're new to the cannabis game or simply bad at math, many people have wondered how many grams are in an ounce. You may be confused when people throw around terms like "grams" and "ounce" like you're in some sort of laboratory (or back in second-grade math class). If you're wondering how these measurements work, how many grams are in an ounce, and what the hell an eighth is, you've come to the right place, my friend! 

With some light reading and this tell-all guide to marijuana mathematics, you'll be an expert in grams, ounces, eighths, and everything in between in no time!

How Many Grams Are In An Ounce of Cannabis?

Marijuana math can get tricky, especially if you're already a couple of joints into the day and just looking for a quick and easy way to get some more weed, so let's do the math and solve your problems. And by "let's," what I really mean is let me do the math for you so you can go back to getting blazed. 

An ounce of weed weighs approximately 28 grams. If you want to get technical, one ounce is actually equal to 28.3495 grams, which can be rounded up to 28.35 grams. Usually, however, suppliers of the stoner variety prefer the round number 28, so for our hazy purposes, an ounce of weed is equal to 28 grams. 

How Do You Convert Grams To Ounces?

Converting grams to ounces is simple math. No long equations or using PEMDAS here; it's just a little multiplication and division! 

To convert grams to ounces, you just need to divide the number of grams by 28 (for our stony purposes only; remember, an ounce is equal to 28.35g in the real world, so don't go around converting non-buds with these measurements).

For example, let's say you want to know how many ounces are in 14 grams. 

14 ÷ 28 = 0.5

This means that there are 0.5 ounces in 14 grams!

Now, let's say you're trying to convert ounces to grams. 

As previously discussed, let's say an ounce of weed is equal to 28 grams. With that information, all you have to do to convert grams to ounces is multiply the number of ounces times 28.

For example, let's say you're trying to figure out how many grams are in a half ounce of weed (and for some godforsaken reason, you don't have access to Google at that moment). All you would do is:

0.5 x 28 = 14 grams 

For any other measurement, just replace the 0.5 for whatever amount of an ounce you're trying to measure (gram, eighth, quarter, etc.)!

What Are the Best Weed Scales?

What Are the Best Weed Scales?

A great way to measure weed (without having to do any tedious math exercises) is to buy a scale. A scale will allow you to gain accurate readings for measurements, portion control, and help you make sure you're not getting scammed off your ass by the sketchy dude you started buying pot from recently. 

You may have heard of all these expensive, spaceship-looking scales on the market today, but to tell you the truth, the priciest items aren't always the most useful. As a matter of fact, scales are pretty simple machines, and the insides of an expensive one look a lot like the insides of cheaper scales. 

Another vital point about scales is that what works for someone else may not work for you. Are you using it to get an accurate dosage? To split up your weed for the week? To sell? 

Depending on your specific scaley needs, the product for you may vary. Below, we'll list a few scales that work well for different circumstances. 

For Beginners

If you're just now getting into the cannabis game (or even if you're just now getting around to weighing weed instead of letting your friends do it for you), using a scale can get a little bit complicated. 

This Premium High Precision Digital Scale by Smart Weigh (who apparently know what they're doing, or so we gather from their name) is the perfect starter kit for any beginner. Complete with a digital scale, a tweezer, calibration weights, pans, and even a portable case, this unsuspecting little product is more than ideal for anyone getting into weed weighing!

Its accuracy is at .001 grams, and it weighs up to 50 grams (a little more than two ounces). Perhaps it's not great for a dealer looking to measure pounds, but it's definitely a remarkable little gadget for a casual toker.

For Stoners On The Go 

The Digital Pocket Scale by Weigh Gram flips open to reveal a small platform and LCD screen and conveniently flips closed so you can fit it in your pocket or bag. This discreet little device is perfect for those looking for a portable and easily accessible scale ready to aid any needy stoner.

It reads anything above .05 grams, has a maximum capacity of 100g, and even comes with a calibration weight. With its modern and seamless look, this sleek appliance will turn heads wherever you go! 

For Precision

Listen, all these scales are perfectly permissible as nice, trustworthy devices for weed weighing. But for some really, really dedicated stoners out there, nice just doesn't cut it. 

If you're looking for razor-sharp precision and bullseye accuracy, you want the GEMINI-20 Portable Precision Digital Scale by American Weigh Scales. It measures whatever is in its cup at .001 grams of accuracy but unfortunately maxes out at 20 grams—this scale is for those patient enough for precision. 

With a shield that flips down over the scale, even microscopic particles won't disrupt small measurements. The scale comes with a removable cup and two calibration weights for extreme accuracy. This stainless-steel beauty is the ultimate weight scale for the ultimate stoner! 

What Are the Different Ways To Measure Weed?

What Are the Different Ways To Measure Weed?

If you're at the beginning of your cannabis journey, you may still have questions about the units of measurement in which marijuana is sold and distributed. Whether you're getting it from a trusty dispensary or the dealer down the street, weed quantities are always the same: grams, eighths, quarters, halves, ounces, and if you're getting crazy (and have the loot to afford it), pounds. 

What Does a Gram Of Weed Look Like?

While this may seem like a straightforward question, the answer is actually a lot more complicated than you think. Despite weighing the same, it all depends on how loosely or tightly the bud is packed. Loosely packed or "fluffy" weed can look bigger than a more compacted flower, meaning that theoretically speaking, a bag of fluff and a dense nug could look very different but still be the same amount of weed. 

Another variable of the looks of pot by weight is moisture levels. Fresh weed contains much more moisture than older pot, meaning that it may result in heavier nugs. So, even though a half-full baggie could look like a lot more than a juicy nug, that isn't always the case.

How To Weigh Cannabis Without a Scale

How To Weigh Cannabis Without a Scale

Scales are obviously the easiest way to weigh weed, but sometimes we find ourselves scale-less and needing a reliable method to figure out how much weed we have. 

Using a Ruler and a Penny

Remember being a kid and making a seesaw out of a ruler in math class? Well, this is kind of like that. Using a ruler, a penny, and a stable item, you can create a makeshift scale! 

  1. Balance the ruler on a narrow, stable item.

  2. Place the penny on one end of the ruler.

  3. Place your bud on the other end. 

And there you have it! A penny weighs around 2.5 grams, so if the penny weighs down the weed, you've got less than 2.5gs, but if the penny shoots up after placing the weed, you've got a decent amount of bud racked up! 

Using the Plastic Hanger Method

This whole section really is all about improvising, adapting, and overcoming. You'd be shocked with the number of things we could do with everyday objects, but plastic hangers have a very convenient benefit: they come pre-balanced.

All you'll need for this DIY is:

  • A plastic hanger

  • Some thread

  • sandwich bags

  • Clothespins

  • Reference weight 

  • Weed (duh!)

This project is extremely simple, and in case you haven't figured out what to do with all these items, the steps are pretty straightforward:

  1. Tie strings to the hanger on opposite sides.

  2. Tie ends of the thread to clothespins. 

  3. Put your weed and reference item in two separate sandwich bags.

  4. Clip them to each clothespin and see which one weighs down the hanger!

This method is pretty simple and a great way to visualize the weight of bud compared to other items. So, say you're wanting 5 grams, but the baggy is looking a little empty. Since we know a penny is around 2.5 grams, you can stick two pennies in a Ziploc and compare your bud's weight to the penny's! 

Eyeballing It

Because of the inconsistencies with what a gram should look like (such as density, stem weight, moisture, etc.), it's really tricky to just eyeball a baggie and know exactly how much weed is in it. 

A general rule of thumb from the olden days, however, is that a gram should spread across the bottom of a sandwich bag evenly and be about the width of your index finger.

But again, because a gram can look different depending on things like strain and humidity, it's always best to figure out some other way to measure!

You Can Also Weigh Weed On Your Phone!

The 21st century response to anything and everything lives right in your pocket. Smartphones are a mind-blowingly convenient device that we often take for granted. 

Let's admit it, we can't take a ruler and hanger everywhere we go. The apps on our phones have slowly but surely taken over the need to carry around Walkmans, contact lists, and calendars. And now, smartphones have the ability to weigh the stuff you place on their screen! Weight scale apps are an amazing way to estimate the amount of weed you have. 

But be warned, these apps are often inaccurate. Using your phone to weigh weed may show inconsistent measurements, so even if you have an eighth exactly, your screen might show a little more or a little less. Screens are, for some reason, unable to show the same weight if the placement of the bud is changed.

For example, if you move the same amount of weed from the top to the bottom of your screen, it does not show the same amount. Although weighing apps are a great tool for when you're in a pinch, smartphones may not be the smartest option for accuracy!

Grams To An Ounce Of Cannabis (One More Time) 

So, now that you've learned about weighing methods and nicknames, let's just go over this whole thing one last time:

  • A gram is exactly what it sounds like: a singular gram of weed. This is the smallest weight of weed you can get at a dispensary, and it should be enough for a few bowl packs or a couple of small joints. 

  • An eighth is perhaps the most common type of marijuana measurement. An eighth of an ounce of weed, this measurement will get you around 3.5 grams of bud and is enough to roll fat blunts or pack a bowl a few times.

  • Quarters are double the size of eighths (7g) and, as the name suggests, a quarter of an ounce. Quarters are where we begin cooking with heat, giving users enough bud to roll, pack, and even bake a few rounds. 

  • A half, or 14 grams, is twice as much weed as a quarter. Asking for this measurement at a local shop or from a dealer should get you enough weed for bowls, blunts, joints, and even homemade edibles for quite some time.

  • Finally, we have the ounce. As you may have guessed, the ounce describes a full ounce of weed, aka 28 grams. 

An Ounce Of Cannabis: Do You Know Your Slang Terms?

If you're new to the world of weed, you may be a little puzzled when people start throwing slang around. Here are some of the most common bud-related slang terms you should know:

  • Nickel Bag: this term refers to five dollars worth of weed. A nickel bag is whatever five bucks can afford ya packed into a baggie!

  • Dime Bag: Similarly, a dime bag shares the same concept with the nickel bag; you get a bag with $10 worth of weed. 

  • A Dub: this term refers to $20 worth of weed, which could get you a gram or two! 

What's the Right Amount of Cannabis For Me?

What's the Right Amount of Cannabis For Me?

The right amount of weed varies from person to person and depends on many variables such as weight, tolerance, and usage frequency. That said, researchers have attempted to create an estimate of how much weed a person should consume:

  • 2 - 5 mg THC: considered a low dose 

  • 5 - 10 mg THC: the most common range for casual consumers

  • 10 - 50 mg THC: considered strong and for experienced consumers 

  • 50 mg THC and above: considered very strong and typically reserved for medical patients and daily consumers

But remember, these are just estimates. You could be a rookie and be fine ingesting 20mg of THC. Or you could feel like 5mg is way too much. How much you take depends entirely on you. You can always smoke more weed, but once you've gone past buzzed and into overload, all there's left to do is wait it out! It's always best to start low and slow and build your way up to the perfect high. 

How Many Grams Are In an Ounce Of Cannabis: Final Thoughts

Understanding the measurements between grams and ounces can be tricky, especially if you're new to the cannabis game. But with this tell-all guide that covers everything from scales and weighing methods to mathematic equations and nicknames, you're not alone anymore!

The bottom line is: an ounce is made up of 28 grams and getting creative is essential in getting yourself out of any weed-related pinch. Be sure to take your time when eating, smoking, or vaping THC; you can always take more but will need to ride out the high if you smoke too much!
