What is equivalent to 500 micrograms (µg) in milligrams?

0.1 mg
0.5 mg
1 mg
2 mg

The correct answer is: 0.5 mg

To convert micrograms to milligrams, it is essential to understand the relationship between these two units of measurement. One milligram (mg) is equal to 1,000 micrograms (µg). Therefore, to convert micrograms to milligrams, you divide the number of micrograms by 1,000. In this case, when converting 500 micrograms to milligrams: 500 µg ÷ 1,000 = 0.5 mg Thus, 500 micrograms is equivalent to 0.5 milligrams. This understanding of the conversion between micrograms and milligrams is crucial for EMTs when administering medications and understanding dosages in both units.
