Here are the essential concepts you must grasp in order to answer the question correctly.
Conversion Factors
Conversion factors are ratios that express how many of one unit are equal to another unit. They are essential in solving problems that require changing measurements from one system to another, such as from pounds to kilograms. For example, knowing that 1 pound is approximately 0.453592 kilograms allows for straightforward conversions.

Weight vs. Mass
Weight is the force exerted by gravity on an object, typically measured in pounds or newtons, while mass is the amount of matter in an object, measured in kilograms or grams. In this context, the weight of a person in pounds can be converted to mass in kilograms using the appropriate conversion factor, acknowledging that weight and mass are related but distinct concepts.
