Formula and Step-by-Step

cups × 114g/cup ÷ 28.3495g/oz = ounces
  1. Start with 3.34 cups of cake flour
  2. 1 cup of cake flour = 114g
  3. 3.34 × 114 = 380.76g
  4. Convert grams to ounces: 380.76 ÷ 28.3495 = 13.43 oz

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

Understanding the Units

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

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

About 13.43 oz, 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.
Multiply the number of cups by 114 (grams per cup for cake flour), then divide by 28.3495 to convert grams to ounces. For 3.34 cups: 3.34 × 114 = 380.76g, then 380.76 ÷ 28.3495 = 13.43 oz.
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: 13.43 oz × 28.3495 = 380.76g, then 380.76g ÷ 114 = 3.34 cups. Or use the Ounces to Cups converter.
