Kilograms to pounds and ounces formula
One ounce of weight is exactly 28.349523125 g and a pound has 16 ounces. First turn the kilograms into ounces:
| m(oz) = m(kg) × 1000 ÷ 28.349523125 |
Then divide the total ounces by 16. The whole number is the pounds. To find the ounces left over, multiply the pounds by 16 and subtract that from the total ounces.
Kilograms to pounds and ounces examples
Example 1: A baby who weighs 3.5 kg
3.5 × 1000 ÷ 28.349523125 ≈ 123.5 oz
123.5 ÷ 16 ≈ 7.719, so there are 7 full pounds
What is left: 123.5 - 16 × 7 = 11.5 oz
A baby who weighs 3.5 kg weighs 7 lb 11.5 oz.
Example 2: Convert 70 kg to pounds and ounces
70 × 1000 ÷ 28.349523125 ≈ 2469.2 oz
2469.2 ÷ 16 ≈ 154.33, so there are 154 full pounds
What is left: 2469.2 - 16 × 154 = 5.2 oz
The result is 154 lb 5.2 oz, or 154.32 lb in decimal form.
Example 3: How many pounds and ounces is one kilogram?
1 × 1000 ÷ 28.349523125 ≈ 35.3 oz
35.3 ÷ 16 ≈ 2.206, so there are 2 full pounds
What is left: 35.3 - 16 × 2 = 3.3 oz
One kilogram is 2 lb 3.3 oz.
Example 4: A 2.5 kg package
2.5 × 1000 ÷ 28.349523125 ≈ 88.2 oz
88.2 ÷ 16 ≈ 5.513, so there are 5 full pounds
What is left: 88.2 - 16 × 5 = 8.2 oz
The package weighs 5 lb 8.2 oz.
