How Much Is 509 Ounces of Black Beans in Cups?
509 ounces of black beans equals 78.42 cups. Black beans has a density of 184g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 509 ounces of black beans
- Convert ounces to grams: 509 × 28.35 = 14,429.91g
- 1 cup of black beans = 184g
- 14,429.91g ÷ 184g/cup = 78.42 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Black beans are dense at 184g per cup. Pour them into the measuring cup and level off without shaking, which settles the beans and increases the weight.

Understanding the Units
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
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.
