The formula is: Pounds = Ounces / 16

Example: Convert 48 ounces to pounds.

1. Weight in ounces: 48 oz
2. Conversion factor: 16 ounces/lb
3. Divide: 48 oz / 16 oz/lb
4. Calculate: 3 lbs
5. Result: 48 ounces is equal to 3 pounds.

Deeper Dive: Why 16 Ounces in a Pound?

The seemingly arbitrary number of 16 ounces in a pound has historical roots. The system of weights and measures evolved over centuries, with different cultures contributing to its development. The avoirdupois system, which includes pounds and ounces, was standardized in England and later adopted in the United States. While the exact reasons for choosing 16 as the conversion factor are complex and debated, it's likely related to the ease of dividing and subdividing quantities. 16 can be easily divided by 2, 4, and 8, making it convenient for various practical applications.
