15 Grams of Sugar to Cups
15 grams of granulated sugar equals ⅛ cup (0.07 US cups), based on 200 g per cup (level cup). In the kitchen, measure 1 tbsp. For best results, weigh granulated sugar with a scale — cup measurements vary with how the cup is filled.
Small amounts like this fit in a single cup measure with room to spare; the fraction matters more than the cup, so level carefully.

How to measure 15 g of granulated sugar without a scale
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.

15 grams of other ingredients
The same weight fills a very different cup depending on density — that's why "grams to cups" always needs the ingredient:
- 15 g of all-purpose flour to cups — ⅛ cup
- 15 g of butter to cups — ⅛ cup
Convert another amount
250 g Granulated sugar = 1 ¼ cups
Exactly 1.25 cups — or measure 1 cup + 4 tbsp.
