Can you use a liquid ounce measuring device to measure dry ounce material?

• A. Sometimes
• B. No
• C. Yes
• D. Only for some products

Answer: (B)

The main idea is the difference between weight and volume. A liquid-ounce measuring device is calibrated to measure volume, not mass. Dry materials have different densities, so the same volume can weigh different amounts. Because of that, using a liquid-volume tool won’t give you a precise dry-ounce (weight) measurement. For accurate pesticide dosing, you should weigh the dry material on a scale to get the correct ounces by weight (or convert using known density, but not rely on a liquid-ounce tool). Even for water, a fluid ounce doesn’t map perfectly to one ounce by weight, so volume measurements aren’t reliable for dry ounces.
