Understanding Whole Wheat Flour Conversions
The Math Behind This Conversion
To convert 1 us cup of whole wheat flour to gram, we use the density of whole wheat flour (0.51 g/ml). A us cup contains 236.59ml, so 1 us cup equals 236.59ml. Multiplying by the density: 236.59ml × 0.51 g/ml = 120.7g.
US vs Metric Cups: Why It Matters
When converting whole wheat flour, the cup size matters significantly. A US cup (236.6ml) of whole wheat flour weighs 121g, while a metric cup (250ml) weighs 128g—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 whole wheat 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.
