All-Purpose Flour
US Teaspoon to Gram
Understanding All-Purpose Flour Conversions
The Math Behind This Conversion
To convert 1 us teaspoon of all-purpose flour to gram, we use the density of all-purpose flour (0.53 g/ml). A us teaspoon contains 4.93ml, so 1 us teaspoon equals 4.93ml. Multiplying by the density: 4.93ml × 0.53 g/ml = 2.6g.
US vs Metric Cups: Why It Matters
When converting all-purpose flour, the cup size matters significantly. A US cup (236.6ml) of all-purpose flour weighs 125g, while a metric cup (250ml) weighs 133g—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 all-purpose 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.
About Our Data
The density value of 0.53 g/ml for all-purpose flour is from the USDA FoodData Central database (ID: 169761). This measurement was taken with all-purpose flour spooned into the measuring cup and leveled. Different measurement methods affect the density: sifted (0.45 g/ml), packed (0.63 g/ml), loose (0.5 g/ml).
