500 mg is equal to 500,000 mcg.
Milligrams (mg) and micrograms (mcg) are both units used to measure mass, but micrograms are one-thousandth the size of a milligram. Therefore, converting from mg to mcg involves multiplying by 1,000. So, 500 mg becomes 500,000 mcg.

Conversion Formula
The formula to convert milligrams to micrograms is:
mcg = mg × 1000.
This works because 1 milligram equals 1,000 micrograms. So multiplying the milligram value by 1,000 gives the equivalent microgram value.
For example, converting 500 mg:
- Start with 500 mg
- Multiply by 1,000: 500 × 1000 = 500,000
- Result is 500,000 mcg
Conversion Example
- Convert 250 mg to mcg:
- Multiply 250 by 1,000
- Result: 250,000 mcg
- Convert 100.5 mg to mcg:
- 100.5 × 1000 = 100,500 mcg
- Decimal values do not change the multiplier
- Convert 0.75 mg to mcg:
- 0.75 × 1000 = 750 mcg
- Small decimal values convert similarly
- Convert 999 mg to mcg:
- 999 × 1000 = 999,000 mcg
- Large values follows same multiplier rule

Conversion Definitions
mg (milligram): A milligram is a unit of mass in the metric system equal to one-thousandth (1/1000) of a gram. It is often used to measure small quantities of substances like medication, chemicals, or nutrients, providing more precise measurement than grams.
mcg (microgram): A microgram is a smaller unit of mass equal to one-millionth (1/1,000,000) of a gram or one-thousandth (1/1000) of a milligram. It is commonly used to express very small amounts of substances, such as vitamins or hormones.
Conversion FAQs
Why do I multiply milligrams by 1,000 to get micrograms?
Multiplying by 1,000 is necessary because a microgram is one-thousandth of a milligram. So, to convert from the larger unit (mg) to the smaller unit (mcg), you scale the value up by 1,000 to express the same mass in smaller units.
Can I convert micrograms back to milligrams? How?
Yes, you can convert micrograms to milligrams by dividing the microgram value by 1,000. Since 1 mg equals 1,000 mcg, dividing reverses the conversion.
Does this conversion change if the substance is liquid?
No, the conversion between mg and mcg is a unit conversion of mass and does not depend on the physical state of the substance. However, density and volume considerations apply when measuring liquids.
Are there common mistakes to avoid in mg to mcg conversions?
People might forget to multiply or divide by 1,000 leading to errors by factors of 1,000. Always check units carefully when converting, especially when dealing with medication dosages where accuracy is critical.
Is 500 mg a large dose compared to 500,000 mcg?
They are exactly the same amount expressed in different units. 500 mg equals 500,000 mcg, so neither is larger, just a different way to represent mass.
