How much is a zip of weed?
A zip of weed is one ounce of cannabis flower, and the US avoirdupois ounce is exactly 28.349523125 grams, or 28.35 grams rounded. That is just under the 28.5 grams of non-concentrated cannabis a licensed California retailer may sell one adult-use customer in a day, so a single zip uses almost all of it.
How much is a zip of weed? One ounce, 28.35 grams, just under California's 28.5 gram daily limit. See the gram math, then shop flower on the Nexus live menu.
Check your address and shop ↗A zip in grams, and the two numbers guides get wrong
Zip is slang for an ounce, and the guides that rank for this question agree on that much. The ounce itself is a legal unit, and the NIST weights and measures tables list one avoirdupois ounce as exactly 0.028349523125 kilogram.
One ranking guide calls a zip exactly 28.5 grams. That figure is California's cap on what a licensed retailer may sell one adult-use customer in a day, not the ounce. Another puts a pound at 448 grams, which is 16 ounces rounded down to 28 grams each and lands about 5.6 grams short of a real pound.
- An eighth of a zip is about 3.54 grams.
- A quarter of a zip comes to about 7.09 grams.
- Half a zip comes to about 14.17 grams.
- A whole zip is 28.35 grams, rounded.
Sixteen zips make a pound
A pound is 16 ounces. So a pound holds 16 zips, and it weighs 453.59237 grams by the NIST tables. A pound of flower is far past what a licensed retailer may sell one adult-use customer in a day.

What one zip means for a day's order in California
California caps what a licensed retailer may sell one adult-use customer at 28.5 grams of non-concentrated cannabis and 8 grams of concentrate per day, under section 15409 of the state cannabis regulations. A zip of flower takes 28.35 of those 28.5 grams and leaves about 0.15 grams.
In practice, an order with a zip of flower has no room for another eighth of flower that day, though concentrate has its own 8 gram allowance and does not compete with the zip. Medicinal patients are treated differently. A retailer may sell a medicinal patient up to 8 ounces of dried flower in a day, or the amount a valid physician's recommendation documents, and adult-use and medicinal limits cannot be added together.
The weight that counts is the one on your paperwork. Every licensed delivery receipt has to describe every item by its weight, volume or another accurate measure, along with the total paid.
