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
