Cup & Gram

Grams of Sugar to Cups

One US cup of granulated sugar weighs 200 grams. To convert grams of granulated sugar to cups, divide the grams by 200 — so 100 g is ½ cup and 200 g is exactly 1 cup.

250 g Granulated sugar = 1 ¼ cups

Exactly 1.25 cups — or measure 1 cup + 4 tbsp.

How to measure granulated sugar

Granulated sugar flows evenly, so scoop-and-level is fine — it settles to nearly the same weight however you fill the cup. That makes sugar the most forgiving ingredient to measure by volume; a level cup is 200 g within a gram or two.
