Are all dry ounce measuring devices the same?

• A. They vary by color
• B. No
• C. Yes
• D. They are the same for all products but vary by weight

Answer: (B)

The concept to keep in mind is that measuring dry ingredients can be done by weight or by volume, and these are not interchangeable. An ounce of weight is a fixed amount of mass, but devices used to measure dry materials come in two main types: scales that display weight in ounces, and cups/spoons that provide a volume measurement (often labeled in ounces as a capacity, not as a weight). Different powders and granular products have different densities and how tightly you scoop or pack them changes their actual weight. So the same volume of one product can weigh more or less than the same volume of another product. That’s why you can’t assume all dry-ounce measuring devices are the same. For accurate dosing, follow the label’s instruction on whether to weigh the product or to measure by a specified volume, and use the appropriate device with proper calibration.
