About ounces and pounds
A pound is exactly 16 ounces, so divide ounces by 16 to get pounds. One ounce is 0.0625 lb. This is the weight ounce (avoirdupois), not the fluid ounce used for drinks.
Food packaging, postage and baby weights in the US are often given in ounces, or in pounds and ounces together, so turning a big ounce figure into pounds is an everyday job.
Examples
- 4 oz (a US stick of butter) is 0.25 lb
- 5 oz (a baseball) is 0.313 lb
- 16 oz (one pound) is 1 lb
- 120 oz (a newborn baby of 7 lb 8 oz) is 7.5 lb
