A prescription indicates to dispense 15 gr. How many grams is this?

• A. 0.5 g
• B. 1 g
• C. 2 g
• D. 3 g

Answer: (B)

To convert grains to grams, it’s important to know the conversion factor: 1 grain is equivalent to approximately 0.0648 grams. Therefore, to find the number of grams in 15 grains, you would multiply 15 by 0.0648. The calculation would look like this: 15 grains × 0.0648 grams/grain = 0.972 grams. When rounding to a practical number for dispensing, 0.972 grams can be approximated to 1 gram. Thus, the response indicating 1 gram reflects the correct understanding of the conversion from grains to grams and provides an accurate dosage in line with standard practice in pharmacy.
