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

About 2.00 oz, based on rolled oats having a density of 90g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 90 (grams per cup for rolled oats), then divide by 28.3495 to convert grams to ounces. For 0.63 cups: 0.63 × 90 = 56.7g, then 56.7 ÷ 28.3495 = 2.00 oz.
For the most accurate results, weigh rolled oats on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup 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.
Reverse the conversion: 2.00 oz × 28.3495 = 56.7g, then 56.7g ÷ 90 = 0.63 cups. Or use the Ounces to Cups converter.
