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.

Frequently Asked Questions

About 0.52 cups, based on black beans having a density of 184g 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 184 (grams per cup). For 3.39 ounces: 3.39 × 28.3495 = 96.10g, then 96.10 ÷ 184 = 0.52 cups.
For the most accurate results, weigh black beans on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 0.52 cups × 184g/cup = 96.10g, then 96.10g ÷ 28.3495 = 3.39 ounces. Or use the Cups to Ounces converter.
