Understanding Cake Flour Conversions
The Math Behind This Conversion
To convert 1 us tablespoon of cake flour to gram, we use the density of cake flour (0.48 g/ml). A us tablespoon contains 14.79ml, so 1 us tablespoon equals 14.79ml. Multiplying by the density: 14.79ml × 0.48 g/ml = 7.1g.
US vs Metric Cups: Why It Matters
When converting cake flour, the cup size matters significantly. A US cup (236.6ml) of cake flour 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
For accurate cake flour measurements, spoon the flour into your measuring cup and level it with a straight edge. Never scoop directly from the bag—this compacts the flour and can give you up to 30% more than intended, which will make your baked goods dense and dry.
