To convert pounds (lbs) to kilograms (kg), you can use the following step-by-step instructions:
Step 1: Understand the conversion factor
1 lb is equal to approximately 0.45359237 kg. This is the conversion factor we will use to convert pounds to kilograms.
Step 2: Set up the conversion equation
To convert 20 lbs to kg, we can set up the equation as follows:
20 lbs * (0.45359237 kg/1 lb)
Step 3: Cancel out the units
In the equation, the unit “lbs” appears in both the numerator and denominator. This allows us to cancel out the unit and only keep the unit “kg” in the numerator.
Step 4: Perform the calculation
Now, we can multiply the numerical values:
20 * 0.45359237 = 9.0718474
Step 5: Round the result (if necessary)
