Crack the Menu: Dispensary Math Made Simple
Finally learn how many grams in an ounce β and four more tricks that’ll save you time and money at the counter.
Scroll
You’re staring at a dispensary menu full of eighths, quarters, and half-ounces, and all you really want to know is how many grams in an ounce so you can figure out whether that deal is actually a deal.
Let’s settle the big one right up front: how many grams in an ounce? It’s 28 grams β technically 28.3495, but every dispensary in DC rounds to 28. Once that number clicks in your head, the entire menu starts making sense. An eighth is 3.5 grams (28 Γ· 8), a quarter is 7 grams, and a half is 14. That’s genuinely the only math you’ll ever need, and you can stop Googling it in the parking lot before you walk in.
We see brand-new patients at Green Legacy every single week who feel intimidated by dispensary menus β and honestly, nobody should feel embarrassed about that. The terminology was designed by stoners, not UX designers. Our budtenders in Shaw will happily walk you through every line item, but having a baseline understanding before you arrive means you can spend more time asking about terpenes and effects instead of decoding weights. If you’d rather skip the trip altogether, our DC cannabis delivery service lets you browse at your own pace from the couch.
I still remember a patient β a retired teacher from Dupont Circle β who came in holding a crumpled napkin with “28 = 1 oz” written on it in blue pen. She’d been buying pre-rolls exclusively for months because the flower menu overwhelmed her. We spent maybe ten minutes together, she bought her first quarter of Blueberry Muffin, and now she’s one of our most confident regulars. She texts our team strain questions like she’s been doing this for decades. That napkin moment? That’s exactly why we wrote this guide.
“Once you memorize that one number β 28 grams β every dispensary menu in DC becomes a menu you can actually read.“

MENU HACKS
Know How Many Grams in an Ounce β Then These
Memorize the Core Fractions
An eighth (3.5g), a quarter (7g), a half (14g), and a full ounce (28g). That’s the whole ladder. Write it on a sticky note and put it in your wallet until it’s second nature β it’ll keep you from overpaying or under-ordering.
Calculate Your Per-Gram Price
Take the listed price and divide by the gram count. A $50 eighth works out to about $14.29 per gram, while a $90 quarter drops you to $12.86. Buying in larger increments almost always saves you money β bulk pricing isn’t just a Costco thing.
Read the Label, Not Just the THC
DC’s medical cannabis program requires tested products with detailed labels. Look beyond the THC percentage β check the terpene profile, harvest date, and total cannabinoid content. A 22% flower with great terps will often outperform a bland 30% every time.
Match Strains to Your Schedule
Don’t just grab whatever’s highest-testing. If you need daytime relief, look for sativa-leaning options with limonene or pinene. Evening wind-down? Indica-dominant strains rich in myrcene or linalool tend to work beautifully. Leafly is a solid resource for digging into individual strain profiles.
Track What Actually Works
Keep a simple notes-app log: strain name, dose, time of day, how you felt. After a few weeks you’ll have a personal cheat sheet that’s worth more than any budtender recommendation. Patterns emerge fast, and you’ll stop wasting money on stuff that doesn’t land right.

Frequently Asked Questions
Your How Many Grams in an Ounce Questions, Answered
So exactly how many grams in an ounce of cannabis?
There are 28 grams in an ounce (28.3495 if you’re being precise, but dispensaries round down to 28). This is the universal standard across every licensed dispensary in DC. Once you know that, every other measurement β eighths, quarters, halfs β is just simple division.
What’s the most cost-effective weight to buy at a DC dispensary?
Almost always, the per-gram price drops as you buy more. A full ounce gives you the best bang for your buck, but a quarter (7g) is the sweet spot for most patients who want savings without a huge commitment. Check our current menu to compare pricing across weights.
How do I become a medical cannabis patient in Washington DC?
You’ll need to register through the DC Health Medical Cannabis Program. A licensed DC physician has to provide a recommendation, and then you apply for your patient card online. The process has gotten way smoother over the past couple years β most people are approved within a few weeks.
Can I get medical cannabis delivered in DC?
Absolutely. Licensed dispensaries like Green Legacy offer medical cannabis delivery throughout DC. It’s legal, it’s discreet, and it’s honestly the most convenient option if you’re in neighborhoods like Capitol Hill, Shaw, or anywhere else in the district. You’ll still need your valid patient card.
How should I store cannabis to keep it fresh after I buy an ounce?
Keep it in an airtight glass jar, away from direct light and heat. A cool, dark cabinet works perfectly. Avoid plastic bags long-term β they build static and knock trichomes off your flower. Stored properly, your bud can stay fresh for several months, which makes buying in larger quantities totally practical.
