250 microgram is equal to 0.25 milligrams.
The conversion from microgram to milligram involves dividing the microgram value by 1000, because 1 milligram equals 1000 micrograms. So, 250 micrograms divided by 1000 gives 0.25 milligrams.

Conversion Formula
The formula to convert micrograms (µg) to milligrams (mg) is:
mg = µg ÷ 1000
This works because 1 milligram is equal to 1000 micrograms. So when you want to find how many milligrams equal a certain number of micrograms, you divide the microgram value by 1000. This reduces the unit size to milligrams, a larger unit than micrograms.
For example, converting 250 micrograms to milligrams:
- Start with 250 µg
- Divide 250 by 1000: 250 ÷ 1000 = 0.25
- So, 250 µg = 0.25 mg
Conversion Example
- Example 1: Convert 500 micrograms to milligrams
- Take 500 µg
- Divide by 1000: 500 ÷ 1000 = 0.5
- Result: 0.5 mg
- Example 2: Convert 1250 micrograms to milligrams
- Start with 1250 µg
- Divide 1250 by 1000: 1250 ÷ 1000 = 1.25
- Answer: 1.25 mg
- Example 3: Convert 75 micrograms to milligrams
- Use 75 µg
- Divide by 1000: 75 ÷ 1000 = 0.075
- So, 0.075 mg

Conversion Definitions
Microgram (µg): A microgram is a unit of mass in the metric system equal to one millionth (1/1,000,000) of a gram. It is often used to measure very small quantities like vitamins, drugs, or chemical substances. The symbol for microgram is µg.
Milligram (mg): A milligram is a metric unit of mass equal to one thousandth (1/1000) of a gram. Milligrams are used to measure small amounts of substances, such as medication doses or food nutrients. The abbreviation for milligram is mg.
Conversion FAQs
Why divide micrograms by 1000 to get milligrams?
Because the milligram is 1000 times larger than the microgram, dividing by 1000 converts the smaller unit into a larger one. This is how metric prefixes work: “micro” means one millionth and “milli” means one thousandth, so 1 mg = 1000 µg.
Can I convert milligrams back to micrograms easily?
Yes, to convert milligrams back to micrograms, you multiply the milligram value by 1000. For example, 0.25 mg times 1000 equals 250 µg. This reverses the division process used in converting micrograms to milligrams.
Are micrograms and milligrams used in medicine dosing?
Yes, both units are common in medicine. Micrograms measure very small doses of potent drugs, like hormones or vitamins, while milligrams are used for larger doses. Accurate conversion is vital to avoid medication errors.
Does the conversion change with different substances?
No, the conversion between micrograms and milligrams is a fixed ratio based on units of mass, so it doesn’t vary with the substance. However, the density or volume of a substance isn’t considered in this conversion, only mass.
Is there any situation where microgram to milligram conversion is not exact?
The conversion between micrograms and milligrams is exact mathematically: 1 mg equals 1000 µg. But measurement tools or rounding might cause minor differences in practice, especially when dealing with very small values.
