Convert Abamperes to Kiloamperes
Convert Abamperes (abA) to Kiloamperes (kA) instantly and accurately.
Conversion Formula
kA = abA × 0.01
About Abamperes
The abampere (abA), also called the biot (Bi), equals exactly 10 A - the current unit of the CGS-EMU (electromagnetic) system. Two long parallel wires each carrying 1 abA and separated by 1 cm experience a force of exactly 2 dyn per centimetre; this definition directly parallels the original 1948 SI definition of the ampere. The abampere appears in nineteenth- and early-twentieth-century electrical engineering literature. 1 abA = 1 Bi = 10 A.
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.
