You’re standing at the counter doing math on your phone, trying to figure out how many grams in an ounce before the budtender notices — and honestly, we’ve all been there.

Let’s settle this once and for all: how many grams in an ounce? It’s 28.3495 grams, but in the cannabis world we round to 28. That number matters more than you’d think, especially when you’re a DC medical cannabis patient trying to make your monthly budget actually work. Once you internalize that figure, every menu price starts making more sense. You can compare eighths, quarters, and halves without that weird mental fog. It’s the kind of basic math that saves you real money over the course of a year.

At Green Legacy, we walk patients through this stuff every single day — no judgment, ever. Whether you’re picking up a quarter in Shaw or scheduling a delivery to Dupont Circle, our team wants you to feel confident about what you’re buying and what you’re spending. We’ve found that patients who understand basic weed measurements tend to waste less product and get better results from their medicine. It sounds simple, but it’s genuinely one of the most empowering things you can learn as a newer patient.

I had a patient last year — retired teacher, lived over in Adams Morgan — who’d been buying pre-rolls exclusively for almost two years because she was intimidated by loose flower math. We spent maybe ten minutes walking her through grams, eighths, and ounces, and she literally texted us the next week saying she’d cut her monthly spend by a third. That’s not an unusual story, either. Once the measurement anxiety disappears, people start experimenting with different formats, dialing in their doses, and actually enjoying the process.
