300 grams is a common sugar measurement in baking recipes. Here's how it converts for different sugar types.
Quick Answer
300 grams of white granulated sugar equals 1½ cups.
By Sugar Type
Sugar Type — Grams per Cup — 300g in Cups
White Granulated — 200g — 1½ cups
Brown Sugar (packed) — 220g — 1⅓ cups
Powdered Sugar — 120g — 2½ cups
Caster Sugar — 190g — 1½ cups
Coconut Sugar — 154g — 2 cups
Why Powdered Sugar is So Different
Powdered sugar (confectioner's sugar) is ground to a fine powder with added cornstarch, creating lots of air between particles. That's why 300g of powdered sugar takes up 2½ cups — nearly twice the volume of the same weight of granulated sugar.
Measuring Tips
White sugar: Scoop and level. Granulated sugar is forgiving since the crystals don't compress much.
Brown sugar: Pack firmly into the cup. The measurement assumes packed brown sugar.
Powdered sugar: Spoon lightly — don't pack. Sift after measuring if the recipe calls for "sifted."
