Weigh it if you can
Volume measures are convenient but imprecise — the same cup can hold noticeably different amounts depending on how the ingredient is packed, how humid the room is, and whether it was sifted. A digital kitchen scale removes the variable entirely, which is why professional and European recipes give weights. If you bake regularly, a scale is the cheapest accuracy upgrade available.
Frequently asked questions
How many grams is 2/3 cups of cake flour?
About 76 grams, or 2.68 ounces.
How many grams in a cup of cake flour?
Roughly 114 grams per US cup.
Is a US cup the same as a metric cup?
No. A US customary cup is 236.6 ml; a metric cup — used in Australia, New Zealand and much of Europe — is 250 ml, about 6% larger. An imperial cup, still seen in older British recipes, is 284 ml. For a cup of cake flour that is a difference of roughly 6.46 g between US and metric.
Should I sift before or after measuring?
It matters, and recipes are often ambiguous. "1 cup sifted flour" means sift first, then measure — which gives less flour than "1 cup flour, sifted", where you measure first. When in doubt, weigh.
