Quick Tip:

To quickly convert pounds to kilograms in your head, without a calculator, you can divide the measurement in pounds in half, then subtract 10% from the result to get a rough conversion.

While this is not a precise method, it is a quick shortcut allowing you to get a rough conversion on the fly when you don't have a calculator handy.

For instance, to convert 200 pounds to kilograms in your head, start by dividing 200 by 2, which is 100.

200 lbs ÷ 2 = 100

Then, subtract 10% of 100 to get the result in kilograms.

100 × 1/10 = 10
100 - 10 = 90

So, 200 pounds is roughly equal to 90 kilograms.

How to Convert Pounds and Ounces to Kilograms

A weight measurement in pounds that is not a whole number is often expressed with the decimal portion in ounces.To convert pounds and ounces to kilograms, you'll need to convert to pounds in decimal form first.

To do this, convert the ounces portion to pounds by dividing it by 16.The result should be a decimal smaller than 1.

Then, add that value to the whole pounds portion to get the total result in pounds as a decimal.

Then, convert pounds to kilograms using the method shown above.

For example, let's find the weight of an object weighing 3 pounds 8 ounces in kilograms.

Start by converting the ounces portion to decimal pounds by dividing 8 oz by 16.8 oz divided by 16 is 0.5.

8 oz ÷ 16 oz/lb = 0.5 lb

Then, add that to the whole pounds, which is 3, resulting in a total of 3.5.

3 lbs + 0.5 lbs = 3.5 lbs

Finally, use the pounds to kilograms formula above to complete the conversion.

3.5 lbs ÷ 2.204623 = 1.5876 kg

Thus, the weight of an object weighing 3 pounds 8 ounces is equal to 1.5876 kilograms.
