Verified step by step guidance1
Understand the units involved: micrograms (mcg) and milligrams (mg) are both units of mass, where 1 mg equals 1000 mcg.
Set up the conversion factor between micrograms and milligrams: \$1\ \text{mg} = 1000\ \text{mcg}$.
To convert 2.4 mcg to mg, use the formula: \(\text{mg} = \frac{\text{mcg}}{1000}\).
Substitute the given value into the formula: \(\text{mg} = \frac{2.4}{1000}\).
Simplify the fraction to find the equivalent amount in milligrams, which will help identify the correct interpretation.
