Formula and Step-by-Step

teaspoons × 4.69g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 258 teaspoons of mashed banana
  2. 1 teaspoon of mashed banana = 4.69g
  3. 258 × 4.69 = 1,209.38g
  4. Convert grams to ounces: 1,209.38 ÷ 28.3495 = 42.66 oz

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

Measuring Tip

Ripeness affects density. Riper fruit mashes more smoothly and packs more densely per cup than firmer fruit. Weigh for the most consistent results.

Understanding the Units

What is a Teaspoon?

In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.

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.

Frequently Asked Questions

About 42.66 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.

For the most accurate results, weigh mashed banana on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon 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.
