Convert pounds to ounces using the exact relationship of 16 ounces per pound. Enter any pound value to receive its equivalent weight in ounces instantly.
Common pound fractions and their ounce equivalents:
Converted value = Source value × Conversion factor
For affine conversions such as temperature, an offset is also applied.The tool applies the relevant factor or temperature offset to the source value. Currency outputs require a current exchange-rate source, while cooking volume-to-weight conversions can vary by ingredient density and measuring method.
Use the Pounds to Ounces Calculator to convert pounds (lb) to ounces (oz) quickly. One pound is exactly equal to 16 ounces in the avoirdupois weight system. Enter the number of pounds and multiply it by 16 to find the equivalent weight in ounces.
To convert pounds to ounces, multiply the weight in pounds by 16.
Conversion factor: 1 pound = 16 ounces
The factor of 16 is exact, so the accuracy of the result depends only on the precision of the starting value. This conversion applies to avoirdupois pounds and ounces, the units commonly used for body weight, food, shipping, and household measurements in the United States.
Ounces = Pounds × 16
Using unit abbreviations, the formula is:
oz = lb × 16
For decimal pound values, use the same formula. For example, 2.5 pounds multiplied by 16 equals 40 ounces.
Convert 5 pounds to ounces:
Therefore, 5 pounds equals 80 ounces.

For a measurement written in pounds and ounces, convert the pounds portion to ounces and then add the remaining ounces. For example, 2 pounds 6 ounces equals 32 ounces plus 6 ounces, or 38 ounces total.
The pound is a unit used to measure mass or everyday weight in the United States customary and British imperial systems. Its standard symbol is lb, while lbs is often used informally for plural values. One avoirdupois pound contains exactly 16 avoirdupois ounces and is defined as exactly 0.45359237 kilograms.
The ounce is a smaller unit of mass or everyday weight in the US customary and imperial systems. Its symbol is oz. One avoirdupois ounce equals exactly 1/16 of a pound, or 28.349523125 grams. A weight ounce should not be confused with a fluid ounce, which measures volume.
There are exactly 16 avoirdupois ounces in one pound.
Multiply the number of pounds by 16. For example, 7 pounds multiplied by 16 equals 112 ounces.
Half a pound equals 8 ounces because 0.5 × 16 = 8.
There are 40 ounces in 2.5 pounds. The calculation is 2.5 × 16 = 40.
Yes. The relationship of 16 avoirdupois ounces per avoirdupois pound is exact. Rounding may only be needed when the original pound value contains many decimal places.
Divide the number of ounces by 16. For example, 48 ounces divided by 16 equals 3 pounds.
Enter a known source value, confirm the direction of conversion and compare the result with the level of precision required. Keep extra decimal places for technical work and round only at the final step.
A decimal pound value can be expressed as a combination of whole pounds and ounces. Keep the whole-number portion as pounds, then multiply the decimal portion by 16 to calculate the remaining ounces.
Remaining ounces = Decimal portion of pounds × 16
For example, convert 4.75 pounds to pounds and ounces:
When a weight includes both pounds and ounces, multiply the pounds by 16 and add the separate ounce value.
Total ounces = (Pounds × 16) + Additional ounces
For example, 6 pounds 5 ounces converts as follows:
(6 × 16) + 5 = 101 ounces
| Fraction of a Pound | Decimal Pounds | Ounces |
|---|---|---|
| 1/16 lb | 0.0625 lb | 1 oz |
| 1/8 lb | 0.125 lb | 2 oz |
| 3/16 lb | 0.1875 lb | 3 oz |
| 1/4 lb | 0.25 lb | 4 oz |
| 3/8 lb | 0.375 lb | 6 oz |
| 1/2 lb | 0.5 lb | 8 oz |
| 5/8 lb | 0.625 lb | 10 oz |
| 3/4 lb | 0.75 lb | 12 oz |
| 7/8 lb | 0.875 lb | 14 oz |
The standard pounds-to-ounces relationship uses the avoirdupois system, in which one pound equals exactly 16 ounces. This is the system used for most food, body-weight, shipping, and household measurements in the United States.
Troy ounces belong to a different measurement system commonly associated with gold, silver, and other precious metals. A troy pound contains 12 troy ounces, so troy measurements should not be converted with the standard 16-ounce factor.
Whole and common fractional pound values often produce exact whole-ounce results. If a pound value produces many decimal places, round the ounce result according to the required level of precision. For everyday measurements, one or two decimal places may be sufficient. Shipping, laboratory, or product-labeling requirements may require a specific rounding rule.
