Cannabis Measurements

One ounce (oz) of cannabis equals 28.3495231 grams.

So when we talk about how many grams in an ounce of cannabis, we don’t discuss just any ounces or grams; instead, we’re talking about precisely 28.3495231 grams for each unit measurement.

That means if you have 1 oz of bud, it will contain 28.3495231 g — no more and no less!

This same standard applies whether you purchase your cannabis from a dispensary or grow it yourself at home. They all use these exact measurements, whether it’s a flower, concentrate, edibles, or other infused products.

Understanding and measuring out quantities accurately is critical when dosing with cannabis properly so as not to over-consume THC (or CBD).

Knowing how much THC is contained within an amount can help ensure that users don’t accidentally consume more than they intend to – thus avoiding any potential adverse effects associated with higher doses, such as anxiety and paranoia.

How Many Grams Are in a “Zip” or “Dub”?

When it comes to buying and selling cannabis, people use various terms to describe the quantity of the substance being purchased. Two of the most common terms are “zip” and “dub,” both used to describe a specific weight of cannabis.

A “zip” of cannabis, also known as a “zipper” or “ounce,” is a term used to describe an ounce of cannabis. In the metric system, one ounce is equivalent to 28.35 grams. Therefore, a zip of cannabis contains 28.35 grams of the substance. This quantity is often preferred by frequent cannabis users, as it provides a large enough amount to last for a reasonable amount of time without having to restock constantly.

A “dub” of cannabis, on the other hand, is a term used to describe a specific weight of cannabis that is smaller than an ounce. The exact weight of the dub can vary depending on where you are located, but it is typically around two grams. Some areas may refer to dub as a “twenty sack” or a “dime bag,” which refers to the cost rather than the weight.

It is important to note that while these terms are commonly used in the cannabis community, they are not universal and may not be recognized by everyone. And if you ever wonder how many grams are in a half-ounce of marijuana, it’s about 14 grams.
