How Much Is 6 Ounces of Brown Sugar in Cups?

6 ounces of brown sugar equals 0.77 cups. That's 170.10g, and Brown sugar has a density of 220g per cup. Because ounces measure weight and cups measure volume, the result depends on the ingredient's density.

Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 220g/cup = cups
  1. Start with 6 ounces of brown sugar
  2. Convert ounces to grams: 6 × 28.35 = 170.10g
  3. 1 cup of brown sugar = 220g
  4. 170.10g ÷ 220g/cup = 0.77 cups

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 an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

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.

Frequently Asked Questions

About 0.77 cups, 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.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 220 (grams per cup). For 6 ounces: 6 × 28.3495 = 170.10g, then 170.10 ÷ 220 = 0.77 cups.
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: 0.77 cups × 220g/cup = 170.10g, then 170.10g ÷ 28.3495 = 6 ounces. Or use the Cups to Ounces converter.
