Explanation

Use 113 g per US cup as the reference when converting powdered sugar from cups to grams.

Recipe scaling stays tied to the US cup standard (236.588 mL) rather than to mixed cup charts. Powdered Sugar can clump, aerate, and settle differently depending on how it is sifted or spooned, so the page keeps one explicit basis instead of mixing preparation styles.

Method & Cup Basis

Method basis: cup-to-weight conversion anchored to the US customary cup (≈236.6 mL).
Applied formula: grams = cups × 113.
Consistency rule: snapshot, calculator, FAQ, and table use the same ingredient-specific basis.

Methodology

Powdered Sugar: cups to grams evidence

Powdered sugar, also known as icing sugar or confectioner’s sugar, is finely milled sugar blended with a small amount of starch to prevent clumping. Its ultra-fine texture allows it to dissolve rapidly, making it useful when quick sweetness integration is required.

Practical use: Powdered sugar is used as a fast-dissolving sweetening agent when rapid integration is needed. It can be incorporated dry, pre-dissolved, or used for surface finishing, contributing sweetness without altering flavor balance.

Ingredient characteristics: Powdered sugar provides clean, direct sweetness with no aromatic character. The perception is soft and immediate due to its fine particle size, contributing sweetness without adding body, acidity, or bitterness.

Direction calculation: Powdered Sugar — 1 US cup equals 113 grams. Reference: 113 g/US cup. Source basis: King Arthur weight chart (unsifted)

Among the 6 reviewed records labeled Salts & Sugars (Rimming/Specialty), the nearest factor to Powdered Sugar is Rock Salt at 192 g/cup: a difference of 79 g/cup (69.9% relative to Powdered Sugar). The observed range in this labeled group is Powdered Sugar at 113 g/cup to Salt at 288 g/cup.

Moisture, preparation, particle size, packing, and temperature can change bulk density, so match the ingredient form named on the page.
