What is the equivalent of 5 mg in micrograms?

To convert milligrams (mg) to micrograms (mcg), it is important to know the conversion factor: 1 mg is equal to 1,000 mcg. Therefore, to find the equivalent of 5 mg in micrograms, you multiply 5 mg by the conversion factor of 1,000 mcg/mg.

Here's the calculation:

5 mg × 1,000 mcg/mg = 5,000 mcg.

This means that 5 mg is equal to 5,000 mcg. Thus, the conversion is accurate, and the correct choice reflects this calculation. The other options do not align with this conversion factor, as they either significantly understate or overstate the value when applying the conversion.
