How Much Is 138 Grams of Black Beans in Cups?
138 grams of black beans equals 0.75 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 138 grams of black beans
- 1 cup of black beans = 184g
- 138g ÷ 184g/cup = 0.75 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 a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
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.
