Cups to Grams: The Baking Conversion Chart You Actually Need
Every ingredient weighs differently per cup. Here is the definitive chart for accurate baking.
1 cup of flour does not weigh the same as 1 cup of sugar. This is why cup measurements produce inconsistent baking results and why professional bakers use weight exclusively. Here are the most common conversions.
Essential Conversions
All-purpose flour: 1 cup = 120g. Bread flour: 1 cup = 130g. Cake flour: 1 cup = 115g. Granulated sugar: 1 cup = 200g. Brown sugar (packed): 1 cup = 220g. Powdered sugar: 1 cup = 120g. Butter: 1 cup = 227g (2 sticks). Cocoa powder: 1 cup = 85g. Rolled oats: 1 cup = 90g. Honey/maple syrup: 1 cup = 340g.
Why Scooping Method Matters
Scooping flour directly from the bag compacts it — you get 140-155g per cup instead of 120g. That extra 20-35g is enough to make cookies dry and cakes dense. The correct method: fluff the flour with a fork, spoon it into the measuring cup, level with a knife. Or better yet: use a $15 kitchen scale and never worry about it again.
