Understanding the Units

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

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.

Frequently Asked Questions

About 17.61 oz, based on peanuts having a density of 146g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 146 (grams per cup for peanuts), then divide by 28.3495 to convert grams to ounces. For 3.42 cups: 3.42 × 146 = 499.32g, then 499.32 ÷ 28.3495 = 17.61 oz.
For the most accurate results, weigh peanuts 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: 17.61 oz × 28.3495 = 499.32g, then 499.32g ÷ 146 = 3.42 cups. Or use the Ounces to Cups converter.
