Understand the Problem
The question is asking for the conversion of weight from pounds to kilograms. To solve this, we will use the conversion factor that 1 pound is approximately equal to 0.453592 kilograms.
Answer
$$ W_k = W_p \times 0.453592 $$
Answer for screen readers
$$ W_k = W_p \times 0.453592 $$
Steps to Solve
- Identify the weight in pounds
Determine the weight that you want to convert from pounds to kilograms. Let's call this weight $W_p$.
- Use the conversion factor
To convert pounds to kilograms, use the conversion factor:
$$ W_k = W_p \times 0.453592 $$
Where:
- $W_k$ is the weight in kilograms
- $W_p$ is the weight in pounds
- Calculate the weight in kilograms
Multiply the weight in pounds by the conversion factor to get the weight in kilograms. For example, if $W_p = 10$ pounds, then:
$$ W_k = 10 \times 0.453592 $$
Calculating this gives:
$$ W_k \approx 4.53592 $$
- Round the result if necessary
Depending on the context, you may want to round the weight in kilograms to a certain number of decimal places.
$$ W_k = W_p \times 0.453592 $$
