## Frequently Asked Questions

**Q: How many ounces are in a pound?**

A: There are exactly 16 ounces in one pound. This is true for both avoirdupois ounces (everyday weight) and the pound-ounce system used in cooking. Troy ounces (used for precious metals) have a different relationship: 12 troy ounces per troy pound.

**Q: How do I convert 5.75 pounds to pounds and ounces?**

A: Take the whole number (5 pounds) and multiply the decimal (0.75) by 16: 0.75 x 16 = 12. So 5.75 pounds = 5 pounds 12 ounces.

**Q: How do I convert ounces to pounds?**

**Q: What is the difference between oz and fl oz?**

A: Ounces (oz) measure weight, while fluid ounces (fl oz) measure volume. They happen to be roughly equal for water (1 fl oz of water weighs about 1.04 oz), but the relationship breaks down for other substances. Always check which one a recipe or label is using.
