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 onion powder having a density of 112g per cup. The exact amount depends on how the ingredient is measured and the specific product.
