Kiloampere quick reference
| Kiloampere | Ampere | Milliampere | Microampere |
|---|---|---|---|
| 1 kA | = 1000 A | = 1000000 mA | = 1000000000 µA |
| 10 kA | = 10000 A | = 10000000 mA | = 10000000000 µA |
| 100 kA | = 100000 A | = 100000000 mA | = 100000000000 µA |
| 1000 kA | = 1000000 A | = 1000000000 mA | = 1000000000000 µA |
Where the kiloampere fits
The next smaller electric current unit is the abampere (abA). 1 kA = 100 abA, and 1 abA = 0.01 kA.
