500 microgram is equal to 0.5 milligrams (mg).
To convert micrograms to milligrams, you divide the number of micrograms by 1000 because one milligram equals 1000 micrograms. So, 500 micrograms divided by 1000 results in 0.5 mg.

Conversion Formula
The formula to convert micrograms (µg) to milligrams (mg) is:
mg = micrograms ÷ 1000
This works because 1 milligram is equal to 1000 micrograms. So, to convert micrograms to milligrams, you simply divide the microgram value by 1000.
For example, converting 500 micrograms:
- Start with 500 µg.
- Divide 500 by 1000.
- 500 ÷ 1000 = 0.5 mg.
So, 500 µg equals 0.5 mg.
Conversion Example
- Convert 750 micrograms to milligrams:
- Take 750 µg.
- Divide 750 by 1000.
- 750 ÷ 1000 = 0.75 mg.
- Convert 250 micrograms to milligrams:
- Start with 250 µg.
- Divide 250 by 1000.
- 250 ÷ 1000 = 0.25 mg.
- Convert 1200 micrograms to milligrams:
- Take 1200 µg.
- Divide 1200 by 1000.
- 1200 ÷ 1000 = 1.2 mg.
- Convert 999 micrograms to milligrams:
- Start with 999 µg.
- Divide 999 by 1000.
- 999 ÷ 1000 = 0.999 mg.

Conversion Definitions
Microgram (µg): A microgram is a unit of mass equal to one millionth (10^-6) of a gram. It is often used in fields like medicine, chemistry, and biology to measure very small quantities of substances, such as vitamins, drugs, or chemical elements.
Milligram (mg): A milligram is a unit of mass equal to one thousandth (10^-3) of a gram. It is used for measuring small masses, especially in pharmaceuticals and nutrition, where precise dosages are required but larger than micrograms.
Conversion FAQs
Why do we divide micrograms by 1000 to get milligrams?
Because one milligram contains exactly 1000 micrograms, dividing the microgram value by 1000 converts it into milligrams. This is due to the metric system’s base-10 structure where each unit differs by powers of ten.
Can I convert milligrams back to micrograms easily?
Yes, to convert milligrams to micrograms, you multiply the milligram value by 1000. This reverses the division used in the microgram to milligram conversion.
Are micrograms and milligrams used interchangeably in prescriptions?
No, they are not interchangeable; they represent different amounts. Using the wrong unit can cause dosing errors. Always check the correct unit specified to avoid mistakes.
Is 0.5 mg a large amount compared to 500 micrograms?
They are exactly the same amount. 0.5 mg equals 500 micrograms because 1 mg = 1000 µg. So, 0.5 mg multiplied by 1000 equals 500 µg.
What instruments measure micrograms and milligrams?
Precision balances or analytical scales are used for measuring these small masses. Microgram measurements require more sensitive instruments than those that measure milligrams.
