Powdered Sugar
Metric Cup to Gram
Understanding Powdered Sugar Conversions
The Math Behind This Conversion
To convert 1 metric cup of powdered sugar to gram, we use the density of powdered sugar (0.48 g/ml). A metric cup contains 250ml, so 1 metric cup equals 250ml. Multiplying by the density: 250ml × 0.48 g/ml = 120g.
US vs Metric Cups: Why It Matters
When converting powdered sugar, the cup size matters significantly. A US cup (236.6ml) of powdered sugar weighs 114g, while a metric cup (250ml) weighs 120g—a difference of 6g (6%). If you're following a recipe from a different country, using the wrong cup size could affect your results. American recipes use US cups, while recipes from Australia, UK, and most other countries use metric cups.
Measurement Tip
Powdered Sugar should be sifted before measuring for the most accurate results. Sifted powdered sugar has a lower density than unsifted, so recipes may specify one or the other.
About Our Data
The density value of 0.48 g/ml for powdered sugar is from the USDA FoodData Central database (ID: 169656). This measurement was taken with powdered sugar spooned into the measuring cup and leveled. Different measurement methods affect the density: sifted (0.42 g/ml), packed (0.6 g/ml).
