Formula and Step-by-Step

cups × 114g/cup = grams
  1. Start with 0.4 cups of cake flour
  2. 1 cup of cake flour = 114g
  3. 0.4 × 114 = 45.6g

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 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 a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 45.60 g, 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). For 0.4 cups: 0.4 × 114 = 45.60 g.
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: 45.60 g ÷ 114 = 0.4 cups. Or use the Grams to Cups converter.
