Converting POUNDS TO OUNCES and Vice Versa
If you want to CONVERT POUNDS TO OUNCES or ounces to pounds, it’s quite simple once you remember the 16-ounce rule.
How to Convert Pounds to Ounces
To convert pounds to ounces, multiply the number of pounds by 16.
For example:
3 pounds × 16 = 48 ounces
How to Convert Ounces to Pounds
To convert ounces to pounds, divide the number of ounces by 16.
For example:
32 ounces ÷ 16 = 2 pounds
Using Decimal Pounds
Sometimes, weight is expressed as a decimal in pounds, such as 2.5 pounds. To find the ounces portion, multiply the decimal by 16.
For instance, 2.5 pounds means:
2 pounds + 0.5 pounds
0.5 × 16 = 8 ounces
