Convert Megaamperes to Gigaamperes
Convert Megaamperes (MA) to Gigaamperes (GA) instantly and accurately.
Conversion Formula
GA = MA × 0.001
About Megaamperes
The megaampere (MA) equals 10⁶ A, encountered in pulsed-power research, electromagnetic launcher experiments, and Z-pinch plasma physics. The Sandia Z Machine delivers peak currents of 20-26 MA to drive inertial confinement fusion implosions; large-scale rail-gun prototypes operate at 1-5 MA; nuclear-weapon electromagnetic pulse can induce megaampere transients in extended conductors. 1 MA = 10⁶ A = 10³ kA.
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.
