Factor1 mA = 1000 μA
Converter
mA
Accepts numbers or expressions, e.g. 150 + 14.7
Result
μA
Rendered to 6 significant figures.
Formula
Formula
μA = mA × 1000
Multiply any value in milliamperes by 1000 to obtain the value in microamperes.
Worked example
Convert 1 mA to μA.
- 01Start with 1 mA.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 μA.
Result1 mA = 1000 μA

FAQ
What is the conversion factor from mA to μA?
1 mA equals 1000 μA. To convert, multiply the value in milliamperes by 1000.
How do I convert 1 mA to μA?
1 mA = 1000 μA. For any value, multiply by 1000.
How do I convert μA back to mA?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 μA = 0.001 mA.
When would I need to convert milliampere to microampere?
Current conversions between mA and μA appear in motor and cable sizing, instrumentation loop design (4–20 mA), battery characterisation and electronics. Amperes are standard for power circuits; milliamperes and microamperes are the working units for signal conditioning and sensor outputs.
Is the conversion exact?
Yes. Both mA and μA are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
