Rendered to 6 significant figures.
Formula
Formula
kA = A × 0.001
Multiply any value in amperes by 0.001 to obtain the value in kiloamperes.
Worked example
Convert 1000 A to kA.
- 01Start with 1000 A.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 kA.
Result1000 A = 1 kA

FAQ
What is the conversion factor from A to kA?
1 A equals 0.001 kA. To convert, multiply the value in amperes by 0.001.
How do I convert 1 A to kA?
1 A = 0.001 kA. For any value, multiply by 0.001.
How do I convert kA back to A?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kA = 1000 A.
When would I need to convert ampere to kiloampere?
Current conversions between A 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 A and kA are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
