1/4 Lb of Powdered Sugar in Cups
1/4 lb of powdered sugar equals 1 ( ~ 1) cup*
About powdered sugar measurements
Powdered (icing) sugar is extremely light, about 0.47 g/ml or just 112 g per US cup, because the milled crystals and cornstarch trap air. It clumps readily, so an unsifted, packed cup weighs well over a sifted one — recipes that call for 'sifted' are expecting the lighter measure.
