Understanding Powdered Sugar Conversions
The Math Behind This Conversion
To convert 1 us tablespoon of powdered sugar to gram, we use the density of powdered sugar (0.45 g/ml). A us tablespoon contains 14.79ml, so 1 us tablespoon equals 14.79ml. Multiplying by the density: 14.79ml × 0.45 g/ml = 6.7g.
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 106g, while a metric cup (250ml) weighs 113g—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.
