Measuring Tip
Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.
Understanding the Units
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
Frequently Asked Questions

The most accurate way is to weigh cake flour on a kitchen scale. If you are measuring by volume, sift or whisk the flour first to break up clumps, then spoon it into the measuring cup and level it off. Do not scoop directly from the bag, which compacts the flour and can increase the weight by 20-30%.
Close, but not exactly. The cups to ounces conversion for cake flour may vary slightly between brands depending on moisture content and how the ingredient is measured.
Weighing is more consistent than volume measuring. A cup of cake flour can vary by 10-20% depending on how it's scooped, packed, or leveled. Weighing gives the same result every time, which is especially important in baking where precision affects texture and rise.
