Formula and Step-by-Step

cups × 225g/cup ÷ 28.3495g/oz = ounces
  1. Start with 2.66 cups of mashed banana
  2. 1 cup of mashed banana = 225g
  3. 2.66 × 225 = 598.5g
  4. Convert grams to ounces: 598.5 ÷ 28.3495 = 21.11 oz

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

Measuring Tip

Mashed and pureed ingredients vary in density depending on texture. A smoother puree packs more densely per cup than a chunky one.

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 an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

Frequently Asked Questions

About 21.11 oz, based on mashed banana having a density of 225g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 225 (grams per cup for mashed banana), then divide by 28.3495 to convert grams to ounces. For 2.66 cups: 2.66 × 225 = 598.5g, then 598.5 ÷ 28.3495 = 21.11 oz.
For the most accurate results, weigh mashed banana 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: 21.11 oz × 28.3495 = 598.5g, then 598.5g ÷ 225 = 2.66 cups. Or use the Ounces to Cups converter.
