Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 114g/cup = cups
  1. Start with 3 ounces of cake flour
  2. Convert ounces to grams: 3 × 28.35 = 85.05g
  3. 1 cup of cake flour = 114g
  4. 85.05g ÷ 114g/cup = 0.75 cups

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Humidity affects cake flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.

Understanding the Units

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

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.

Frequently Asked Questions

About 0.75 cups, based on cake flour having a density of 114g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 114 (grams per cup). For 3 ounces: 3 × 28.3495 = 85.05g, then 85.05 ÷ 114 = 0.75 cups.
For the most accurate results, weigh cake flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring cup and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring cup and level it off, you will get about 114 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 125.4 to 142.5 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 0.75 cups × 114g/cup = 85.05g, then 85.05g ÷ 28.3495 = 3 ounces. Or use the Cups to Ounces converter.
