Ounce to Pound Conversion

To convert ounces to pounds, use a conversion factor (a ratio that equals 1 for unit conversion). Since 1 pound = 16 ounces, the conversion factor is $\frac{1\ \text{pound}}{16\ \text{ounces}}$. Multiply the given ounce value by this factor to cancel the ounce units and get pounds.

Use the conversion factor $\frac{1\ \text{pound}}{16\ \text{ounces}}$. Multiply 52 ounces by this factor: $52\ \text{ounces} \times \frac{1\ \text{pound}}{16\ \text{ounces}} = 3.25\ \text{pounds}$. The ounce units cancel out, leaving pounds.
