About Gram & Cup

Hi, I'm Patrick. I make Gram & Cup: a fast, no-nonsense place to answer the question every baker runs into sooner or later, which is how much a cup of something actually weighs.

Recipes written in cups are convenient, but a cup measures space, not amount. A cup of flour, a cup of honey and a cup of chocolate chips all weigh very different amounts, and the same cup of flour can weigh a quarter more depending on how it is filled. Weighing ingredients fixes that, and this site exists to make converting easy.

What you'll find here

• Conversion charts for 25 common baking ingredients, by the cup, tablespoon, teaspoon, gram and ounce.
• A converter on every ingredient page that works in your browser.
• Guides on measuring accurately, converting recipes, cup sizes around the world and more.

How the numbers are worked out

Each ingredient has one typical weight per US cup, measured the way recipes intend: flour spooned and leveled, brown sugar packed. Every other amount on the site is calculated from that figure. The sources and methodology page explains the details and lists every ingredient's figures in one place.

Real ingredients vary with brand, moisture and technique, so treat these numbers as reliable starting points. For the most consistent results, weigh your ingredients.

Keeping it accurate

The site is reviewed and updated every week. New ingredients and guides are added regularly, and figures are corrected when a better reference turns up.
