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.

The most accurate way is to weigh granulated sugar on a kitchen scale. If you are measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly from the container, which packs more in and gives a heavier result.
Close, but not exactly. The cups to ounces conversion for granulated sugar may vary slightly between brands depending on moisture content and how the ingredient is measured.
Weighing is more consistent than volume measuring. A cup of granulated sugar can vary by 10-20% depending on how it's scooped, packed, or leveled. Weighing gives the same result every time, which is especially important in baking where precision affects texture and rise.
