You’re standing at the counter doing mental math, trying to figure out how many grams in an ounce while the budtender waits patiently — we’ve all been there, and honestly, it’s the most common question we hear at the shop.

Let’s settle this once and for all: how many grams in an ounce? It’s 28.3495 grams, but the cannabis world rounds to a clean 28. That number matters more than you think, especially if you’re a DC cannabis patient watching your budget in 2026. The difference between buying a gram at a time and buying in bulk can save you hundreds of dollars over a year. And yet, most folks walk into a dispensary without understanding the basic math behind their purchase. Once you’ve got these measurements down, everything else — from comparing menus to calculating your monthly spend — gets a whole lot easier.

At Green Legacy, we see patients every single day who are surprised by how much further their money stretches when they buy smart. Our Shaw dispensary team actually keeps a little conversion chart behind the counter (yes, laminated — we’re that serious about it). Whether you’re picking up in person or using our DC medical cannabis delivery service to get it dropped in Adams Morgan or Dupont Circle, understanding weight tiers is the first step to becoming a more confident patient. We’re not here to upsell you — we’re here to make sure you never overpay for what you need.

I’ll never forget the patient — let’s call her Diane — who came in every Friday buying a single gram of the same hybrid for her arthritis. After about the sixth week, one of our budtenders gently walked her through the bulk pricing. Diane’s jaw literally dropped. She’d been spending almost $100 more per month than she needed to. She switched to half-ounce pickups, joined our rewards program, and now she’s basically our unofficial brand ambassador in Petworth. That’s the kind of moment that reminds us why this stuff matters beyond just numbers on a scale.
