mg to ug Converter - Milligram to Microgram
Milligram (mg) to Microgram (μg) (ug)
Direct answer
1 mg = 1,000 ug
ug = mg × 1,000
Converter
Conversion formula
ug = mg × 1,000
mg = ug × 0.001
Example: 10 mg = 10 × 1,000 = 10,000 ug.

Conversion factor for mg to μg (ug)
The conversion factor of 1,000 arises because both the milligram (mg) and the microgram (μg or ug) are defined as multiples of the base kilogram (kg). The milligram is 0.000001 kg, and the microgram is 1 × 10⁻⁹ kg.
Definition
A milligram (mg) is a unit of mass equal to 0.000001 kilograms. A microgram (μg or ug) is a unit of mass equal to 1 × 10⁻⁹ kilograms.
Principle
To derive the conversion, express both units in the common base unit of kilograms (kg). Dividing the milligram's factor (0.000001) by the microgram's factor (1 × 10⁻⁹) yields a factor of 1,000, meaning 1 mg equals 1,000 ug.
Assumptions
- The conversion is based on the definitions of mg and ug relative to the base kilogram (kg).
- The base unit for mass is the kilogram (kg).
Cautions
- The conversion factor is exact within the metric system definitions.
- Always use the appropriate number of significant figures for your calculation.
