Convert Kiloamperes to Gigaamperes
Convert Kiloamperes (kA) to Gigaamperes (GA) instantly and accurately.
Conversion Formula
GA = kA × 1.000000000e-6
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 Gigaamperes
The gigaampere (GA) equals 10⁹ A, a scale that lies beyond any man-made device and arises only in extreme astrophysical or geophysical contexts. Large-scale magnetospheric Birkeland field-aligned currents between Earth's ionosphere and magnetosphere are estimated at 1-10 MA total, well below 1 GA; however, pulsar magnetosphere discharge models and neutron-star lightning analogues are sometimes expressed in gigaampere terms. 1 GA = 10⁹ A = 10³ MA.
