How to use it
- Type the value in the kiloamperes box.
- Read the result in amperes as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
A = kA × 1,000
Multiply the value in kiloamperes by 1,000 to get amperes.
Example
To convert 25 kA to amperes: 25 × 1,000 = 25,000 A.

About the units
- Kiloampere
- A kiloampere is exactly 1000 amperes, used for short-circuit ratings of switchgear, welding and lightning currents.
- Ampere
- The SI base unit of current, equal to one coulomb of charge passing per second. Since 2019 it is defined by fixing the elementary charge at 1.602176634 × 10^-19 C.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many amperes are in one kiloampere?
1 kA = 1,000 A exactly.
How do I convert kiloamperes to amperes?
Use A = kA × 1,000. For example, 25 kA = 25,000 A.
How many kiloamperes are in one ampere?
1 A = 0.001 kA.
How many milliamperes are in one ampere?
One ampere is exactly 1000 milliamperes, so a charger rated 2 A delivers up to 2000 mA.
Can I convert amps to watts?
Not directly, because power in watts is current times voltage. A current of 2 A at 5 V gives 10 W.
