How to quickly estimate pounds to kilograms
Want to do the math in your head? Here’s a quick method.
- Divide the number of pounds by 2.
- Subtract 10% of the result.
So, for 12.5 pounds: (12.5 / 2) = 6.25. Then, 6.25 – (6.25 0.1) = 5.625 kg.
This is just an estimate, of course. The exact conversion factor will always give you a more precise result.
Converting pounds and ounces to kilograms
Here’s how to convert weights that are given in pounds and ounces:
- Convert the ounces to pounds by dividing the number of ounces by 16 (since there are 16 ounces in a pound).
- Add that number to the pounds. For instance, 3 pounds and 8 ounces is 3 + (8/16) = 3.5 pounds.
- Multiply the total number of pounds by 0.453592. So, 3.5 pounds 0.453592 = 1.587 kg.
