To convert pounds (lb) to ounces (oz), use this simple rule: 1 lb = 16 oz.
Formula: ounces = pounds × 16
Steps:
Example:
3 lb × 16 = 48 oz
There are 16 ounces in 1 pound. This is the standard conversion for avoirdupois weight, used in the US and many other places.
Multiply the number of pounds by 16.
Formula: ounces = pounds × 16
Remember this simple fact: 1 lb = 16 oz.
If you can double a number, you can scale from there: 2 lb = 32 oz, 4 lb = 64 oz.
2 pounds = 32 ounces.
You get this by multiplying 2 × 16.
5 pounds = 80 ounces.
That’s 5 × 16.
10 pounds = 160 ounces.
That’s 10 × 16.
0.5 pounds = 8 ounces.
Half of 16 is 8.
0.25 pounds = 4 ounces.
One-quarter of 16 is 4.
1.5 pounds = 24 ounces.
That’s 1 × 16 plus 0.5 × 16 (16 + 8).
Yes. Ounces are a smaller unit, so the number in ounces is larger.
For example, 3 lb = 48 oz.
In everyday use, pounds and ounces describe weight. In science, they often represent mass in a practical sense, even though the strict physics meaning can differ.
The 16 oz per 1 lb rule is for the avoirdupois system, which is the most common system for body weight, food, and packages. Some special systems differ.
A standard pound (avoirdupois) is always 16 ounces.
Other types exist, like the troy pound, but it’s not used for common goods.
An avoirdupois ounce is used for most items and food. A troy ounce is used for precious metals like gold and silver. They are not the same size, so don’t mix them.
No. Fluid ounces (fl oz) measure volume, not weight.
Ounces (oz) measure weight. The conversion depends on the liquid’s density, so you can’t use 16 to convert pounds to fluid ounces.
Shipping rates often use weight in pounds but may list details in ounces. Cooking also uses ounces for smaller amounts. Converting helps you measure the right amount and avoid mistakes.
Use 16 as 8 + 8.
To convert, multiply by 8, then double it.
Example: 7 lb → 7 × 8 = 56, doubled = 112 oz.
