How to measure it accurately
Powdered (icing) sugar traps air and clumps as it sits, so sift it before measuring. Weight is far more reliable than volume.
Use the full cooking converter
For any other volume or weight unit, or to convert weight back to volume, use the Cooking Converter and select Powdered Sugar from the ingredient list.
