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 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?
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.
Frequently Asked Questions
1 cup of tomato paste is 9.24 oz. The conversion depends on the density of tomato paste and scales proportionally for any amount.
The most accurate way is to weigh tomato paste on a kitchen scale. If you are measuring by volume, spoon it into the measuring cup and pack gently to fill air gaps. Thick pastes can trap air pockets, so pressing lightly gives a more consistent measurement than scooping loosely.
Approximately. The cups to ounces result for tomato paste can vary depending on preparation - how finely it is cut, mashed, or processed. Treat this as a close estimate.
Weighing is more consistent than volume measuring. A cup of tomato paste can vary by 10-20% depending on how it's scooped, packed, or leveled. Weighing gives the same result every time, which is especially important in baking where precision affects texture and rise.
