A scale shows 120 lbs. How many kilograms does the patient weigh? (1 lb = 0.453592 kg)

To find out how many kilograms the patient weighs when they are recorded at 120 lbs, you simply multiply the weight in pounds by the conversion factor from pounds to kilograms, which is 0.453592 kg per lb.

Starting with the weight in pounds:

120 lbs × 0.453592 kg/lb = 54.43104 kg.

When rounded to two decimal places, this value becomes 54.43 kg. Thus, the correct calculation directly supports that the patient's weight in kilograms is indeed approximately 54.43, which aligns with the provided answer choice. This conversion process is essential for accurately translating weight measurements from one unit to another, particularly in medical settings where kg is often the standard.
