Rendered to 6 significant figures.

Formula

Formula
μA = A × 1000000

Multiply any value in amperes by 1000000 to obtain the value in microamperes.

Worked example

Convert 1 A to μA.

  1. 01Start with 1 A.
  2. 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 μA.
Result1 A = 1.00000e+6 μA

FAQ

What is the conversion factor from A to μA?
1 A equals 1000000 μA. To convert, multiply the value in amperes by 1000000.
How do I convert 1 A to μA?
1 A = 1.00000e+6 μA. For any value, multiply by 1000000.
How do I convert μA back to A?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 μA = 1e-6 A.
When would I need to convert ampere to microampere?
Current conversions between A 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 A and μA are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
