Why weigh pastry flour instead of measuring cups?
A cup measures volume, but recipes really care about how much pastry flour you add by weight. One US cup of pastry flour is taken as 106 g here, cited from King Arthur Baking for the exact chart form “pastry flour”, and every conversion on this page routes through that figure. Volume-to-volume and weight-to-weight steps are exact, but the cup→gram crossing depends on product form and how the pastry flour is packed, so a kitchen scale is the reliable way to hit the same result every time.
