Convert Abamperes to Gigaamperes
Convert Abamperes (abA) to Gigaamperes (GA) instantly and accurately.
Conversion Formula
GA = abA × 1.000000000e-8
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 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.
