Conversion Formula
The formula to convert micrograms (mcg) to milligrams (mg) is:
mg = mcg ÷ 1000
This works because the prefix “micro-” means one-millionth (10-6) and “milli-” means one-thousandth (10-3). Since 1 mg = 1000 mcg, dividing the microgram value by 1000 converts it into milligrams.
Example:
- Given: 70 mcg
- Divide 70 by 1000: 70 ÷ 1000 = 0.07 mg
- Result: 70 mcg equals 0.07 mg
Conversion Example
- Convert 150 mcg to mg:
- Start with 150 mcg
- Divide by 1000: 150 ÷ 1000 = 0.15 mg
- Answer: 0.15 mg
- Convert 500 mcg to mg:
- Take 500 mcg
- Divide by 1000: 500 ÷ 1000 = 0.5 mg
- Result: 0.5 mg
- Convert 25 mcg to mg:
- Start with 25 mcg
- Divide by 1000: 25 ÷ 1000 = 0.025 mg
- Result: 0.025 mg
- Convert 800 mcg to mg:
- Begin with 800 mcg
- Divide by 1000: 800 ÷ 1000 = 0.8 mg
- Answer: 0.8 mg

Conversion Definitions
mcg (microgram): A microgram is a metric unit of mass equal to one millionth of a gram (0.000001 g). It is used to measure very small quantities, especially in fields like medicine and chemistry where precise dosing or measurements is required at microscopic scales.
mg (milligram): A milligram is a unit of mass in the metric system equal to one thousandth of a gram (0.001 g). It is a common unit used in pharmaceuticals, nutrition, and science to express small but measurable amounts of substances, larger than micrograms.
Conversion FAQs
Why is 1000 used to convert mcg to mg?
The number 1000 is used because one milligram contains 1000 micrograms. The prefixes milli- and micro- differ by a factor of 1000, so dividing micrograms by 1000 changes the units to milligrams.
Is 70 mcg a large or small dose compared to mg?
70 mcg is a very small amount compared to milligrams because 1 mg equals 1000 mcg. So, 70 mcg equals only 0.07 mg, which is less than one-tenth of a milligram.
Can I convert mcg to mg without a calculator?
Yes, converting micrograms to milligrams is simple: just divide the microgram value by 1000. For example, 70 mcg divided by 1000 is 0.07 mg, so mental math or basic division works fine.
Does the conversion change for different substances?
No, the conversion between mcg and mg is based on units of mass, so it remains the same regardless of the substance. 70 mcg of any material equals 0.07 mg of that material.
What is the difference between mcg and mg in everyday use?
Milligrams are commonly used for measuring larger small amounts like vitamins or drugs, while micrograms measure much smaller doses, such as hormone levels or trace elements. Both relate by a factor of 1000, but their use depends on precision needed.
