Powdered Sugar (Unsifted): US Cups & tbsp to Grams (g) & Ounces (oz) Conversion
Convert volumes of unsifted powdered sugar (confectioners' sugar, icing sugar), measured by spooning lightly into US cups and tablespoons (tbsp), to its approximate weight in metric grams (g) and imperial/US ounces (oz).

Important Considerations for Unsifted Powdered Sugar:
The weight of **unsifted** powdered sugar can vary more significantly than sifted due to compaction. A common range is **120-140 grams per US cup** (approximately 4.23-4.94 ounces) when spooned lightly into the cup. Scooping directly can result in even heavier weights.
If a recipe calls for "1 cup powdered sugar, sifted," you should measure 1 cup of unsifted sugar first, then sift it. If it calls for "1 cup sifted powdered sugar," you sift first, then measure.
For recipes requiring precision (like macaronage or delicate frostings), using a kitchen scale and measuring by weight is always the best practice.
