Frequently asked questions
Why do different flours have different weights per cup?+
Different flours have different densities. All-purpose flour is about 125g per cup, while whole wheat flour is about 130g because it contains more bran and germ. The protein content and milling process also affect how densely the flour settles in a measuring cup.
Should I use a kitchen scale or measuring cups?+
A kitchen scale is always more accurate, especially for baking where precision matters. Flour can be compressed or aerated, leading to 20% variation in cup measurements. Professional bakers always weigh ingredients. This tool helps you convert either way.
How do I measure flour correctly with cups?+
Spoon the flour into your measuring cup, then level it off with a straight edge (like the back of a knife). Never scoop directly with the cup — that compacts the flour and adds 15-20% more than intended.
Are these conversions accurate for all brands?+
These conversions are based on industry standards from King Arthur Baking and USDA data. Most brands use similar densities, but slight variations are normal. For best results, use a kitchen scale when precision matters.
Do I need to sift flour before measuring?+
Most recipes specify either "1 cup flour, sifted" (measure then sift) or "1 cup sifted flour" (sift then measure). These are different amounts! Our conversion assumes unsifted, spooned-and-leveled flour unless otherwise noted.
