Measuring Tip
Thick pastes like tomato paste can trap air pockets when measured by volume. Spoon into the measuring cup and press gently to fill gaps, then level off. Weighing on a scale avoids this variability entirely.
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?
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.

Approximately. The ounces to cups result for tomato paste can vary depending on preparation - how finely it is cut, mashed, or processed. Treat this as a close estimate.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of tomato paste fills a different number of cups than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
