1500 mcg is equal to 1.5 mg.
The conversion from micrograms (mcg) to milligrams (mg) involves dividing the microgram value by 1000 because 1 milligram equals 1000 micrograms. So, 1500 mcg divided by 1000 results in 1.5 mg.

Conversion Formula
To convert micrograms (mcg) to milligrams (mg), divide the number of micrograms by 1000. This is because one milligram contains exactly 1000 micrograms. The formula is:
mg = mcg ÷ 1000
This works since the metric system is based on powers of ten, making conversion between units straightforward by shifting decimal places.
Example:
- Given 1500 mcg, divide by 1000.
- 1500 ÷ 1000 = 1.5
- So, 1500 mcg equals 1.5 mg.
Conversion Example
- Convert 2500 mcg to mg:
- Divide 2500 by 1000.
- 2500 ÷ 1000 = 2.5
- Therefore, 2500 mcg equals 2.5 mg.
- Convert 750 mcg to mg:
- Divide 750 by 1000.
- 750 ÷ 1000 = 0.75
- So, 750 mcg equals 0.75 mg.
- Convert 980 mcg to mg:
- Divide 980 by 1000.
- 980 ÷ 1000 = 0.98
- Thus, 980 mcg equals 0.98 mg.
- Convert 1234 mcg to mg:
- Divide 1234 by 1000.
- 1234 ÷ 1000 = 1.234
- Hence, 1234 mcg equals 1.234 mg.

Conversion Definitions
mcg (microgram): A microgram, abbreviated as mcg, is a unit of mass in the metric system equal to one millionth of a gram. It’s commonly used to measure very small quantities of substances such as vitamins, medicines, or chemicals where precision is needed.
mg (milligram): A milligram, abbreviated as mg, is a metric unit of mass equal to one thousandth of a gram. It is larger than a microgram and often used to express doses of medications or nutritional content in food where slightly larger amounts are involved.
Conversion FAQs
Why do we divide micrograms by 1000 to get milligrams?
Because the metric system units scale by factors of ten, a milligram is exactly 1000 times larger than a microgram. Dividing the microgram value by 1000 converts it properly into milligrams by shifting decimal places three places to the left.
Can I convert mcg to mg without a calculator?
Yes, since conversion only requires dividing by 1000, you can move the decimal point three places to the left on the number representing micrograms. For example, 1500 mcg becomes 1.5 mg by shifting the decimal.
Are mcg and mg used interchangeably?
No, they are different units measuring mass. Micrograms are much smaller than milligrams. Using them interchangeably can cause dosage mistakes, especially in medical settings where precision matters.
How accurate is the conversion from mcg to mg?
The conversion is exact because metric units are based on powers of ten. Dividing micrograms by 1000 will always result in the correct milligram value without rounding errors unless decimals are truncated.
What types of substances are measured in micrograms instead of milligrams?
Substances requiring very precise or small amounts, like vitamins (e.g., vitamin B12), hormones, or pollutants, are often measured in micrograms. Milligrams are used when slightly larger quantities are involved.
