Conversion Formula
The formula to convert milligrams (mg) to micrograms (ug) is simple: multiply the milligram value by 1,000. This works because “micro” means one-millionth and “milli” means one-thousandth, so 1 mg equals 1,000 ug.
Formula:
micrograms (ug) = milligrams (mg) × 1000
For example, converting 25 mg:
- Start with the value in mg: 25 mg
- Multiply by 1,000: 25 × 1000 = 25,000
- Result is 25,000 ug
Conversion Example
- 10 mg to ug
- 10 mg × 1000 = 10,000 ug
- Multiply the mg value by 1000 to get micrograms.
- 3.5 mg to ug
- 3.5 × 1000 = 3,500 ug
- Multiplying decimal mg value works the same, just times 1000.
- 0.75 mg to ug
- 0.75 × 1000 = 750 ug
- Small numbers convert by same multiplication.
- 50 mg to ug
- 50 × 1000 = 50,000 ug
- Double the 25 mg example, result doubles.
- 1.2 mg to ug
- 1.2 × 1000 = 1,200 ug
- Decimal inputs convert identically.

Conversion Definitions
Milligram (mg): A milligram is a unit of mass in the metric system equal to one-thousandth (1/1000) of a gram. It is commonly used in measuring small quantities of substances, especially in medicine and chemistry, to provide precise dosing or measurements.
Microgram (ug): A microgram is a unit of mass equal to one-millionth (1/1,000,000) of a gram. It is used to measure extremely small amounts of a substance, often in pharmacology or laboratory settings where tiny quantities are important.
Conversion FAQs
Why multiply milligrams by 1000 to get micrograms?
Because the microgram is smaller than the milligram by a factor of 1,000, each milligram contains exactly 1,000 micrograms. The prefix “micro” means one-millionth, and “milli” means one-thousandth, so scaling between them involves multiplying by 1,000 to convert mg to ug.
Can I convert micrograms back to milligrams easily?
Yes, converting micrograms to milligrams is done by dividing the microgram value by 1,000. This reverses the conversion process, scaling the smaller unit back to the larger one.
Are milligrams and micrograms used interchangeably in prescriptions?
No, they are not interchangeable because they differ by a factor of 1,000. Confusing them can lead to dosing errors. Always check the units carefully when reading medication labels or instructions.
Is the conversion factor the same for all substances?
Yes, the conversion factor between mg and ug is a physical unit conversion and does not change based on the substance. It’s a fixed relationship between units of mass, independent of material type.
What tools can I use to convert mg to ug quickly?
You can use online converters, calculators with unit conversion features, or simple multiplication by 1,000. The included conversion tool on this page lets you enter any mg value and instantly see the ug result.
