Formula and Step-by-Step

cups × 220g/cup = grams
  1. Start with 1.29 cups of brown sugar
  2. 1 cup of brown sugar = 220g
  3. 1.29 × 220 = 283.8g

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

Measuring Tip

If your brown sugar has hardened, microwave it with a damp paper towel for 20 seconds. Hard brown sugar is still the same weight but impossible to measure by volume.

Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

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 283.80 g, based on brown sugar having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 220 (grams per cup for brown sugar). For 1.29 cups: 1.29 × 220 = 283.80 g.
For the most accurate results, weigh brown sugar on a kitchen scale. If measuring by volume, pack it firmly into the measuring cup and level it off. This conversion assumes packed brown sugar, which is the standard method.
Brown sugar should be firmly packed into the measuring cup. This is the standard method and what this conversion assumes. Loosely measured brown sugar will weigh significantly less.
Reverse the conversion: 283.80 g ÷ 220 = 1.29 cups. Or use the Grams to Cups converter.
