Weed Measurements Chart: Grams, Ounces, QP, Half Pound and Pound

Buying GuidesOctober 21, 20263 min read

Quick answer: A quarter pound (QP) is 4 ounces, or about 113 grams. A half pound is 8 ounces (about 227 grams), and a pound is 16 ounces (about 454 grams). A half ounce is 14 grams and a zip, or full ounce, is 28 grams.

Cannabis is sold in a mix of metric and imperial weights. Grams at the small end, ounces in the middle and pounds at the wholesale end. That’s why a menu can feel confusing. This chart puts every common size on one page, so you can compare a 2 ounce pack with a QP or a pound at a glance.

Weed measurements chart

Name	Slang	Ounces	Grams (exact)	Grams (how it’s usually sold)
One gram	a g, a dub sack (sometimes)	0.035 oz	1 g	1 g
Eighth	an eighth, a slice	1/8 oz	3.54 g	3.5 g
Quarter ounce	a quarter, a q	1/4 oz	7.09 g	7 g
Half ounce	a half, a half zip	1/2 oz	14.17 g	14 g
Ounce	a zip, an O, a zone	1 oz	28.35 g	28 g
Two ounces	a two-zip	2 oz	56.7 g	56 g
Quarter pound	a QP, a quap	4 oz	113.4 g	112 g
Half pound	an HP, a half P	8 oz	226.8 g	224 g
Pound	an LB, a P, an elbow	16 oz	453.6 g	448 g

The last column matters. Most shops round an ounce down to 28 grams, so every bigger size gets rounded down too. At HIGH THCA our product weights are listed by ounces and pounds, so a pound means 16 ounces.

Cannabis slang for weights

Zip: one ounce. The name comes from the zip-top bag an ounce used to come in.
QP: a quarter pound, or 4 ounces. Not a quarter ounce.
HP: a half pound, or 8 ounces.
P, LB or elbow: a full pound. “Elbow” is a play on “L-B”.
Eighth: an eighth of an ounce, about 3.5 grams. The most common single purchase at a dispensary.

How many grams in a quarter pound (QP)?

A quarter pound has 113.4 grams. In everyday buying it’s called 112 grams, because 4 ounces at 28 grams each is 112. A QP sits between consumer sizes and wholesale. It’s the size a lot of regular smokers buy to save on price, and the size many shops buy to test a new strain before they commit to pounds.

How many grams in a half pound and a pound?

A half pound is 8 ounces, which is 226.8 grams (sold as 224). A pound is 16 ounces, or 453.6 grams (sold as 448). If you’re working out cost per gram, divide the price by the gram count you actually receive.

How many ounces in a QP or a half pound?

There are 4 ounces in a QP and 8 ounces in a half pound. Two QPs make a half pound and four QPs make a pound.

How many joints can you roll from an ounce?

Joint size	Joints per ounce (28 g)	Joints per QP (112 g)	Joints per pound (448 g)
0.5 g (a slim joint)	56	224	896
0.75 g (a standard joint)	37	149	597
1 g (a king size)	28	112	448

Rolling your own takes time. If you’d rather skip it, our THCA pre-rolls come in 100-count and diamond-infused 50-count packs. Want to learn the technique anyway? See our guide to joints, blunts and pre-rolls.

Buying by weight: ounces vs QP vs pound

The bigger the weight, the lower the price per gram. That’s the whole reason sizes like a QP exist. Here’s how most buyers use each size:

2 ounce packs: a good fit for regular smokers who want variety without buying in bulk. Browse THCA flower ounces.
QP: a stock-up size for consumers, and a sample size for shops trying a new strain.
Half pound and pound: the shop and reseller sizes. See THCA flower wholesale for every strain available by the pound.

How to check the weight you receive

A pocket scale that reads to 0.01 grams is enough for ounces. For QPs and pounds, use a kitchen or shipping scale that reads in grams. Weigh the flower without the bag, or weigh the empty bag and subtract it.

Flower can lose a little weight as it dries out in storage. That’s moisture, not missing product, and it’s one reason good storage matters. Our guide to storing THCA flower covers humidity packs and jars.
