How to Convert

To convert grams to cups, you’ll need to know the density of the ingredient you’re working with. The density of a substance is the ratio of its mass to its volume. Different substances have different densities, so the conversion factor will vary depending on what you’re measuring. Here are a few common conversion factors:

  • Water: 1 gram/milliliter
  • Sugar: 0.7 gram/milliliter
  • Flour: 0.6 gram/milliliter
  • Butter: 0.9 gram/milliliter

Remember to divide the number of grams by the conversion factor. For example, to convert 100 grams of sugar to cups, you would divide 100 by 0.7, which is approximately 1.4 cups.

Tips on converting

  • Keep in mind that these conversions are approximate and may not be exactly accurate due to differences in ingredient densities and variations in measuring techniques.
  • If you don’t have a measuring cup on hand, you can also use common household objects as a makeshift measuring tool. For example, a 1/4 cup is about the same as a 4-ounce juice glass or a 1/2 cup is about the same as a coffee mug.
