Conversion Formula
The formula to convert micrograms to milligrams is:
milligrams = micrograms ÷ 1000
This works because 1 milligram contains 1,000 micrograms. Therefore, when you have a value in micrograms, dividing it by 1,000 gives the equivalent in milligrams.
For example, to convert 30 micrograms to milligrams:
- Start with the value in micrograms: 30 µg
- Divide by 1,000: 30 ÷ 1000 = 0.03
- The result is 0.03 milligrams
Conversion Example
- Convert 150 micrograms to milligrams:
- Start: 150 µg
- Divide by 1000: 150 ÷ 1000 = 0.15 mg
- Final value: 0.15 milligrams
- Convert 75 micrograms to milligrams:
- Start: 75 µg
- Divide by 1000: 75 ÷ 1000 = 0.075 mg
- Final value: 0.075 milligrams
- Convert 500 micrograms to milligrams:
- Start: 500 µg
- Divide by 1000: 500 ÷ 1000 = 0.5 mg
- Final value: 0.5 milligrams
- Convert 20 micrograms to milligrams:
- Start: 20 µg
- Divide by 1000: 20 ÷ 1000 = 0.02 mg
- Final value: 0.02 milligrams
