If a patient requires 0.02 g of a medication, how many mg is that?

• A. 5 mg
• B. 20 mg
• C. 200 mg
• D. 2 mg

Answer: (B)

To convert grams to milligrams, you need to know the relationship between these two units. One gram is equal to 1,000 milligrams. Therefore, to convert 0.02 grams into milligrams, the calculation is as follows: 0.02 g × 1,000 mg/g = 20 mg. This calculation shows that 0.02 grams is equivalent to 20 milligrams. Understanding this basic unit conversion is essential in pharmacy to ensure accurate medication dosing, as medications are often prescribed in grams or milligrams. Hence, the correct answer is indeed 20 mg.
