How Much Is 31.98 Ounces of Tomato Paste in Cups?
31.98 ounces of tomato paste equals 3.46 cups. That's 906.62g, and Tomato paste has a density of 262g per cup. Because ounces measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 31.98 ounces of tomato paste
- Convert ounces to grams: 31.98 × 28.35 = 906.62g
- 1 cup of tomato paste = 262g
- 906.62g ÷ 262g/cup = 3.46 cups
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 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.
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.
