Factor1 mA = 1e-6 kA

Converter

mA

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1kA

Rendered to 6 significant figures.

Formula

Formula
kA = mA × 1e-6

Multiply any value in milliamperes by 1e-6 to obtain the value in kiloamperes.

Worked example

Convert 1.00000e+6 mA to kA.

  1. 01Start with 1.00000e+6 mA.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 kA.
Result1.00000e+6 mA = 1 kA

FAQ

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