Understanding Self-Rising Flour Conversions
The Math Behind This Conversion
To convert 1 us teaspoon of self-rising flour to gram, we use the density of self-rising flour (0.52 g/ml). A us teaspoon contains 4.93ml, so 1 us teaspoon equals 4.93ml. Multiplying by the density: 4.93ml × 0.52 g/ml = 2.6g.
US vs Metric Cups: Why It Matters
When converting self-rising flour, the cup size matters significantly. A US cup (236.6ml) of self-rising flour weighs 123g, while a metric cup (250ml) weighs 130g—a difference of 7g (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 self-rising 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.
