Convert Kiloamperes to Milliamperes
Convert Kiloamperes (kA) to Milliamperes (mA) instantly and accurately.
Conversion Formula
mA = kA × 1000000
About Kiloamperes
The kiloampere (kA) equals 10³ A, the scale of industrial arc furnaces, short-circuit fault currents in power networks, and lightning return strokes. Medium-frequency induction furnaces for steel melting operate at 1-10 kA; substation busbar faults can reach 50-100 kA; a typical cloud-to-ground lightning stroke carries 10-30 kA for tens of microseconds. 1 kA = 10³ A = 10⁻³ MA.
About Milliamperes
The milliampere (mA) equals 10⁻³ A, the everyday unit in consumer electronics and safety standards. Standard LEDs operate at 5-30 mA; USB 2.0 ports supply up to 500 mA; USB-C fast-charging delivers 3 000-5 000 mA. The milliampere is also the clinically important range for electric shock - ventricular fibrillation threshold is around 100 mA, and 1 mA is the threshold of perception. 1 mA = 10⁻³ A = 10³ µA.
