1/8 cup of powdered sugar in grams
1/8 cup of powdered sugar weighs about 15 grams.
| Grams | 15 g |
|---|---|
| Ounces | 0.53 oz |
| Tablespoons | 2 tbsp |
| Teaspoons | 6 tsp |
| Milliliters (volume) | 30 ml |
This is based on 1 cup of powdered sugar = 120 g, so 1/8 cup of powdered sugar is 1/8 × 120 ≈ 15 g.
How to measure 1/8 cup of powdered sugar
By weight (most accurate): set your bowl on a kitchen scale, press tare, and add 15 g of powdered sugar.
By volume: Use 2 level tablespoons. Most measuring-cup sets do not include a 1/8 cup.
Powdered (confectioners’) sugar is fine and airy, so a cup weighs far less than a cup of granulated sugar. Sift it if the recipe says “sifted”.
Why powdered sugar weighs what it does
Powdered sugar is about 49% lighter than the same volume of water, which weighs about 237 g per cup. That is why you can't convert cups to grams without knowing the ingredient.
