⚖️ Pounds ⇄ Kilograms Converter
Powered by CalculatorUp.comHow to Convert Pounds and Kilograms
Pounds (abbreviated as lbs) and kilograms (abbreviated as kg) are both ways to measure mass, but they come from distinct systems. The Imperial system, which is used in the US, uses pounds. The Metric system, which is used around the world and in science, uses kilograms.
You can't just compare the two systems directly because they are different. You need a conversion factor.
Step 1: Find out what the conversion factor is
To change pounds to kilograms, you need to know how the two units are always related:
1 lb = 0.45359237 kg, or Each pound is equivalent to 0.45359237 kilograms.
This number informs you how many kilograms are in one pound. You may round it to 0.454 kg for all intents and purposes.
Step 2: Use the formula for conversion
If you want to change pounds into kilograms, use this formula:
Kilograms = Pounds × 0.45359237
or
Kg = Lbs × 0.45359237
For example:
If you weigh 180 pounds and want to know how many kilograms it is, using the formula:
0.45359237 × 180 = 81.6466 kg
180 × 0.45359237 = 81.6466 kg
When you round it to two decimal places, it comes out to 81.65 kg.
Step 3: Learning About the Process
In other words, calculating what part of a kilogram each pound is is the same as multiplying by 0.45359237. This ratio turns pounds into the smaller metric unit since a pound is less than half a kilogram.
Step 4: A table to help you remember quickly
This table shows the average weights for several things:
Lbs (pounds) | Kilograms (kg)
50 | 22.68
100 | 45.36
150 | 68.04
200 | 90.72
250 | 113.40
Step 5: Change using Tools
You can transform pounds to kilograms by hand using the formula, but you can also:
-
Use a calculator
-
Open a spreadsheet tool like Google Sheets or Excel and type
=A1*0.45359237into a cell -
Write a little program in a language like PHP, Python, or JavaScript
Conclusion
It's easy to shift pounds to kilograms if you know the conversion factor. No matter what you're doing—like weighing yourself, sending stuff, or doing math—this method will give you the right answer.
