Convert Gigaamperes to Statamperes
Convert Gigaamperes (GA) to Statamperes (statA) instantly and accurately.
Conversion Formula
statA = GA × 2.997924580e+18
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.
About Statamperes
The statampere (statA) is the current unit of the CGS-Gaussian system, equal to 1 statC/s = 1/(10c) A ≈ 3.336 × 10⁻¹⁰ A (exact, since c = 2.997 924 58 × 10⁸ m/s is exact). Two long parallel wires each carrying 1 statA and separated by 1 cm experience a force of 1/c² dyn per centimetre. The statampere is used in electrostatics texts where Coulomb's law is written without ε₀. 1 statA ≈ 333.6 pA.
