Weed measurements in plain English

Weed measurements are just weight: grams and ounces in a few standard sizes you see on every menu. Once you match the slang to the numbers, ordering stops feeling like a code and you can compare prices without guessing. You do not need to be a math person; you only need a short ladder of common weights and how they relate to each other.

Straight numbers are kinder than guessing when you buy weed.

The standard weed weights in grams

Most weed is weighed in grams but talked about in fractions of an ounce, and the pattern is simple once you see it. Shops use a short ladder of sizes that repeat everywhere: 1 g, 3.5 g, 7 g, 14 g, 28 g. Those line up with what people call a gram, an eighth, a quarter, a half and an ounce, and prices are built around them. If you only remember one thing, make it this: an eighth is 3.5 g and an ounce is 28 g; from there, the rest is just doubling up the grams.

A quick cheat sheet you can remember

Here is the basic mapping between weed slang, ounces and grams.

Unit Ounce fraction Grams (weed rounding)
Gram — 1 g
Eighth 1/8 oz 3.5 g
Quarter 1/4 oz 7 g
Half 1/2 oz 14 g
Ounce 1 oz 28 g

Technically, one ounce is about 28.35 g, but in the weed world everyone rounds that to 28 g and builds from there. Once you see it laid out, each step up just doubles the grams, which makes it easy to scan a menu and decide whether you want a small tester or a bag that will last a while. When you want to see those sizes on real strains, you can browse them on Shop THCA flower.

What those weed amounts look like in a bag

The same weight can look like a tiny pinch or a big pile, but the scale is what counts. A gram, an eighth or an ounce each has its own rough “feel” in a bag, yet density, trim and packaging change how full that bag seems. Once you know the usual range for each size, you stop worrying that a properly weighed bag looks “too small”.

Roughly how each size shows up in a bag

A gram of weed is usually one small to medium nug, or a couple of smaller ones, and often covers just a corner of the bag. An eighth (3.5 g) looks like a small layer of nugs across the bottom, while a quarter (7 g) is closer to a loose handful. A half (14 g) and a full ounce (28 g) start to fill a sandwich‑ or quart‑size bag, so they feel like a stash rather than a sample.

A gram of weed is often enough for a single solo session, while an eighth (3.5 g) gives you room to try a strain over several sessions. A quarter (7 g) suits you if you already like the strain and reach for it often. A half (14 g) or ounce (28 g) makes more sense when you know you will use that strain while it still smells and tastes fresh.

Why the same weight can look different

Regulated shops rely on calibrated scales because weight is what matters, not how “full” the bag looks. Dense, tight buds can make 3.5 g look small because they pack down; fluffy, airy buds can make the same 3.5 g look huge. Grind level, stem content and whether the weed sits in a flat pouch or a round jar all change the look without changing the grams. When you want to see how 3.5 g, 7 g, 14 g and 28 g options are packed and priced on real strains, check each size on Shop THCA flower.

Weed measurements and THCA flower at Krippy Express

Krippy Express only sells hemp‑derived THCA flower, not marijuana, and the same weed measurements apply to every bag. Under federal law, hemp means flower with 0.3% delta‑9 THC or less by dry weight, even when the THCA percentage is high. You should still treat THCA flower like strong weed, start small and wait before you go back for more, and remember that the shop is for adults 21 and over.

Standard sizes on the Krippy Express menu

Every strain on the Krippy Express menu comes in the same four standard sizes: 3.5 g, 7 g, 14 g and 28 g. That means the ladder you learned earlier lines up exactly with what you see when you pick a strain and choose a weight. You can grab 3.5 g to try a new strain, move up to 7 g if you already like it, or choose 14 g if you reach for the same jar most days. Go for 28 g when you know you will use it while it still smells and tastes fresh. What you select on the menu is the weight that lands in your plain box.

COAs, lot numbers and storage

Each product page tells you the weight, the THCA percentage, the delta‑9 THC percentage and links to the batch COA. The lot number printed on the bag matches the COA, so you can check lab results for exactly what you bought instead of a generic sample. To keep your THCA flower in good shape, keep the resealable foil bag sealed, cool and out of direct light. If you buy 14 g or 28 g at a time, moving the flower into a glass jar in a dark cupboard is even better. When you are ready to match weights, strains and lab numbers in one place, you can do it straight from Shop THCA flower.

Legality, shipping and “Can Krippy Express ship here?”

The weight you buy is one thing; where that bag can legally ship is another. Federal law draws the hemp line at 0.3% delta‑9 THC or less by dry weight, but states handle weed, hemp and THCA differently, and those rules change over time. You should always check how your own state treats hemp‑derived THCA flower before you order or travel with it, because possession limits and smokable hemp rules can be stricter than the federal baseline.

The federal hemp line and THCA in practice

That same 0.3% delta‑9 THC by dry weight line is what keeps hemp‑derived THCA flower in the hemp category at the federal level. The THCA number is usually much higher, and heat from smoking, vaping or baking converts THCA into delta‑9 THC. That is why “total THC” matters once heat is involved, and why you should treat THCA flower with the same respect you give strong weed, even though the legal category is different.

Where Krippy Express can and cannot ship

Krippy Express ships hemp‑derived THCA flower by USPS to many states but does not ship to these six:

  • Arkansas
  • Idaho
  • Minnesota
  • Oregon
  • Rhode Island
  • Texas

Checkout blocks those states so you cannot accidentally place an order there. Other states have their own rules on smokable hemp, total THC and how much you can legally possess at one time, so it is on you to confirm what is allowed where you live. If you are unsure, start at Is weed legal in your state? for a simple state‑by‑state view, then check your state's current rules for any updates. This is general information, not legal advice.

FAQ

How many grams are in an eighth, quarter, half and ounce of weed?

An eighth is 3.5 g, a quarter is 7 g, a half is 14 g, and an ounce is 28 g. Shops round to these numbers for easy labels.

What weed amount should I start with?

Most people start with 3.5 g (an eighth) to try a new strain. Start small and wait before using more.

Why does my eighth sometimes look small or big?

Bud density, trim and packaging change how 3.5 g looks. The scale, not the bag's fullness, is what counts.

Can Krippy Express ship THCA flower to my state?

Krippy Express does not ship to Arkansas, Idaho, Minnesota, Oregon, Rhode Island or Texas. Check your state's current rules before you order.

Do weed measurements work the same for hemp‑derived THCA flower and regular weed?

Yes. A gram is a gram, and an eighth is 3.5 g for both. The difference is legal, not mathematical.
