How It Works

How to Convert Sugar Cups to Grams

Formula

Grams = Cups x Sugar Density (g/cup)

Sugar density varies significantly by type. Brown sugar is measured packed, while powdered sugar is much lighter per cup due to air.

Sugar Weights Per Cup

  • Granulated: 200 g
  • Brown (packed): 220 g
  • Powdered: 120 g
  • Raw/Turbinado: 150 g

    • Worked Example

    Convert 1 cup of granulated sugar to grams.

    cups = 1sugar_density = 200
    1. 01Granulated sugar density: 200 g per cup.
    2. 02Multiply: 1 x 200 = 200 g.
    3. 031 cup of granulated sugar weighs 200 grams.

    Frequently Asked Questions

    Why is brown sugar measured packed?

    Brown sugar contains molasses which makes it sticky and clumpy. Packing it into the cup gives a consistent measurement. A packed cup weighs about 220 g.

    Why does powdered sugar weigh less per cup?

    Powdered sugar is ground very fine and contains cornstarch, trapping a lot of air between particles. This makes it only about 120 g per cup.

    Can I substitute brown sugar for white sugar?

    Generally yes, in a 1:1 ratio by volume or weight. Brown sugar adds moisture and a molasses flavor, which slightly changes texture and taste.
