1000 micrograms is equal to 1 milligram (mg).
To convert micrograms to milligrams, you divide the number of micrograms by 1000 because there are 1000 micrograms in 1 milligram. Thus, 1000 micrograms divided by 1000 equals 1 milligram.

Conversion Formula
The formula to convert micrograms (µg) to milligrams (mg) is:
mg = micrograms ÷ 1000
This works because one milligram equals 1000 micrograms. When converting, you divide the microgram value by 1000 to find how many milligrams it represents.
For example, if you have 5000 micrograms:
- Start with 5000 µg
- Divide by 1000: 5000 ÷ 1000 = 5
- Result: 5 mg
Conversion Example
- Convert 2500 µg to mg:
- Take the value: 2500
- Divide by 1000: 2500 ÷ 1000 = 2.5
- Answer: 2.5 mg
- Convert 750 µg to mg:
- Start with 750 micrograms
- Divide by 1000: 750 ÷ 1000 = 0.75
- So, 0.75 mg
- Convert 12345 µg to mg:
- Value is 12345
- Divide by 1000: 12345 ÷ 1000 = 12.345
- Result is 12.345 mg
- Convert 980 µg to mg:
- Take 980 micrograms
- Divide by 1000: 980 ÷ 1000 = 0.98
- Final value: 0.98 mg

Conversion Definitions
Micrograms (µg): A microgram is a unit of mass in the metric system equal to one millionth of a gram. It is often used to measure very small quantities such as vitamins, drugs, and chemicals. The symbol µg combines the Greek letter “mu” with the letter g for gram.
Milligrams (mg): A milligram is a metric unit of mass equal to one thousandth of a gram. It is larger than a microgram and commonly used in medical dosages and scientific measurements. The abbreviation mg stands for milli (thousandth) and gram.
Conversion FAQs
Can I convert micrograms to milligrams without a calculator?
Yes, since 1 milligram equals 1000 micrograms, you can convert micrograms to milligrams by dividing the value by 1000 mentally for simple numbers. For example, 2000 µg is 2000 ÷ 1000 = 2 mg. For harder numbers, a calculator helps avoid errors.
Why is converting micrograms to milligrams important in medicine?
Precise dosing in medicine requires correct unit conversions. Many medications are prescribed in milligrams but measured in micrograms in labs or packaging. Converting ensures the patient receives the correct dose, preventing underdose or overdose risks, which could be harmful or ineffective.
Is the conversion factor always 1000 between µg and mg?
Yes, the factor remains constant because metric prefixes micro- and milli- define fixed multiples of the gram. One milligram is exactly 1000 times larger than one microgram, so the conversion is always dividing or multiplying by 1000 depending on direction.
What happens if I confuse micrograms and milligrams in dosage?
Confusing these units can lead to serious errors. Taking milligrams instead of micrograms may cause overdosing by 1000 times, which can be dangerous or toxic. Careful measurement and conversion is necessary in healthcare and scientific contexts to avoid harmful mistakes.
