The kiloampere is a large current unit equal to 1,000 amperes, used for short-circuit and lightning current levels.
It became standard in power distribution and industrial electrical systems for expressing large current magnitudes.
Measurement system: International System of Units (SI, multiple unit). SI equivalent: 1 kA = 1000 A.
