How do you convert 18 pounds to kilograms?

• A. Multiply by 2.2
• B. Add 2.2
• C. Divide by 2.2
• D. Subtract 2.2

Answer: (C)

To convert pounds to kilograms, the appropriate mathematical operation involves dividing the weight in pounds by a conversion factor, which is approximately 2.2. This is because 1 kilogram is equivalent to about 2.2 pounds. Therefore, when you have a weight given in pounds, dividing by this conversion factor will yield the equivalent weight in kilograms. For example, if you take 18 pounds and divide it by 2.2, you would get approximately 8.18 kilograms. This method allows for an accurate translation of weight measurements from the imperial system to the metric system, which is crucial in pharmacy practice for dosages that may need to be calculated in different units.
