Formula and Step-by-Step

cups × 200g/cup = grams
  1. Start with 3.99 cups of granulated sugar
  2. 1 cup of granulated sugar = 200g
  3. 3.99 × 200 = 798g

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

Measuring Tip

Sugar is one of the easier dry ingredients to measure by volume because the crystals pack relatively consistently compared to flour or cocoa powder.

Understanding the Units

What is a Cup?

A cup is a US customary unit of volume equal to 236.588 milliliters or 8 fluid ounces. It is the most common volume measurement in American recipes. One cup can be divided into 16 tablespoons or 48 teaspoons.

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 798.00 g, based on granulated sugar having a density of 200g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 200 (grams per cup for granulated sugar). For 3.99 cups: 3.99 × 200 = 798.00 g.
For the most accurate results, weigh granulated sugar on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Granulated and powdered sugars should be spooned into the measuring cup and leveled off. Do not pack them unless the recipe specifically says to.
Reverse the conversion: 798.00 g ÷ 200 = 3.99 cups. Or use the Grams to Cups converter.
