Unit definition
Kiloamperes (kA) One kiloamperes equals 1,000 ampere.
Unit history
Kiloamperes is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert kA to ampere.
3. Convert the base value to mA and apply your display precision.
Understand the result before using it
Kiloamperes to Milliamperes converts a value measured in Kiloamperes (kA) into the equivalent value in Milliamperes (mA). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 1000 ÷ 0.001
Assumptions
- Kiloamperes and Milliamperes represent the same current quantity.
- The input is expressed in kA; the output is expressed in mA.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 kA = 1,000,000 mA. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a kA measurement in a document that expects mA.
- Compare a kiloamperes value with a value reported in milliamperes.
- Check the kA-to-mA arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse kA with another unit that has a similar name or symbol.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.

Questions about this calculation
How do I convert Kiloamperes to Milliamperes?
result = input × 1000 ÷ 0.001 Using the displayed relationship, 1 kA equals 1,000,000 mA.
How many Milliamperes are in one Kiloamperes?
One Kiloamperes is 1,000,000 Milliamperes. The displayed digits may be rounded.
Can I reverse the kA to mA conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts mA back to kA.
Is the Kiloamperes to Milliamperes result exact?
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
