Step 2:: Understand the Conversion
To convert milligrams (mg) to grams (g), we need to know the relationship between these units of mass. - 1 gram (g) = 1000 milligrams (mg)
Step 3:: Set Up the Conversion
\frac{30 \text{ mg}}{1} \times \frac{1 \text{ g}}{1000 \text{ mg}} = x \text{ g}
We want to convert 30 mg to grams.
Step 4:: Calculate the Conversion
x = \frac{30}{1000} = 0.03 \text{ g}
Step 5:: Verify the Calculation
- 30 mg ÷ 1000 = 0.03 g - This matches the conversion formula
Final Answer
Key Points: - To convert mg to g, divide by 1000 - 30 mg = 0.03 g - The correct answer is option A
