How Much Is 2.31 Ounces of Tomato Paste in Cups?
2.31 ounces of tomato paste equals 0.25 cups. Tomato paste has a density of 262g 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 2.31 ounces of tomato paste
- Convert ounces to grams: 2.31 × 28.35 = 65.49g
- 1 cup of tomato paste = 262g
- 65.49g ÷ 262g/cup = 0.25 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?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
