The Correct Answer and Explanation is:
To convert 215 pounds (lb) to kilograms (kg), you can use the conversion factor:
1 lb = 0.453592 kg.
So, to convert 215 pounds to kilograms:
215 lb×0.453592 kglb=97.522 kg.215 \, \text{lb} \times 0.453592 \, \frac{\text{kg}}{\text{lb}} = 97.522 \, \text{kg}.215lb×0.453592lbkg=97.522kg.
Thus, 215 pounds is approximately 97.52 kilograms.
Explanation:
The pound (lb) is a unit of mass commonly used in the United States and other countries that follow the imperial system. The kilogram (kg), on the other hand, is the standard unit of mass in the metric system, used worldwide.
To convert between the two units, we multiply the value in pounds by a constant factor. The exact conversion factor is 0.453592, meaning each pound is equivalent to about 0.453592 kilograms.
This conversion is straightforward since it’s a simple multiplication:
- Start with the number of pounds you want to convert (in this case, 215 lb).
- Multiply by the conversion factor (0.453592).
- Result: You get the mass in kilograms, which for this example is 97.522 kg.
The result is rounded to two decimal places, as commonly done in everyday measurements. Therefore, 215 pounds is equal to 97.52 kilograms.
This type of conversion is useful when switching between systems for scientific, educational, or personal purposes, ensuring measurements are consistent.
