Flower sizes are kind of a mess, measurement-wise. Grams on one end, fractions of an ounce on the other, and nobody really explains how they fit together. It’s easy to lose track of what you’re actually getting, and that’s before you even look at what’s in the bag.
The Sizes, in Plain Numbers
Quick version. A gram is the base unit. An eighth is one-eighth of an ounce, or 3.5 grams. A quarter is 7 grams. A half is 14. An ounce gets sold as 28.
That last one’s a little funny. A true ounce is about 28.35 grams. Retail just rounds it down to 28. Not a big gap, but it’s a nice reminder that these names are shortcuts. They’re not exact measurements.
Do the Price-Per-Gram Math
Want to compare sizes fairly? Divide the price by the grams. A $100 ounce comes out to roughly $3.57 a gram. A $40 eighth comes out to about $11.43 a gram. Now you’re comparing apples to apples.
Try it with a quarter while you’re at it. A $60 quarter lands around $8.57 a gram. Put all three next to each other, and in this example the bigger sizes come out ahead on price per gram.
But price per gram is only half of it. Stems, seeds, and shake all count on the scale. Old, dried-out flower counts too. A cheap bag can be carrying a lot of weight you’re never going to use.
It helps to know the lingo. Shake is the little bits that break off flower as it gets handled. Trim is the small leaves cut away during processing. Neither one is a crime on its own. But if you’re paying a flower price, you want mostly flower.
A Local Guide Worth Reading
Some shops around town have written their own explainers on this. One local shop with a counter in both the Crossroads and Waldo put together a guide to grams and ounces. It goes through each size, the per-gram math, and what tends to pad a bag. It also mentions that most of its flower is sold by the gram, with bigger sizes depending on the strain and what’s in stock. The shop is open to customers 21 and over.
Who Checks the Weight on a Label?
For packaged goods in general, there’s a whole system behind that number on the label, and most people never give it a thought. The National Institute of Standards and Technology publishes Handbook 133, Checking the Net Contents of Packaged Goods. It’s a step-by-step guide for testing whether packages meet the legal rules for the amount printed on them. State and local weights and measures officials are the main people using it.
Most shoppers will never crack it open, and that’s fine. It’s just good to know the amount printed on a package isn’t a guess. In most retail, it has to meet legal requirements.
Look Before You Pay
Whatever size you go with, your own eyes are a solid check. Ask to see the product before you buy. Look for stems and dust settling at the bottom. Smell it. If it gets weighed in front of you, make sure the scale reads zero before anything goes on it. A fair price on a bag you can actually look at beats a low price on one you can’t.
And if a shop won’t let you look first? That tells you something too.
