22.7 kg

Practice makes perfect
Let's start by copying the given statement. 50lb≈ kg Converting between pounds (lb) and kilograms (kg) will involve using a conversion factor. 1kg/2.20lb Multiplying 50lb by this conversion factor will convert it to kilograms.
50lb*1kg/2.20lb
50lb*1kg/2.20lb
50lb*1kg/2.20lb
50*1kg/2.20
50kg/2.20
22.727272kg
22.7kg
To complete the given statement, we will substitute 22.7 into the blank space. 50lb≈22.7kg

Conversions can be made both within or between the Metric System and the Imperial System — which is also known as the U.S. Customary System. Conversions can also be made for different measurement types: length, mass, temperature, time, area, or volume.
Conversion factors between different units of measurement
All across the globe, humans use conversion factors on a daily basis. Want to use a recipe that is written using milliliters? Convert it! Want to compare your height to that of an Olympic athlete? Convert it! You can read more about applications of conversion factors in our original content.
