GA·t = A·t × 1.000000000e-9
About Ampere-turns
The ampere-turn (A·t) is the SI practical unit of magnetomotive force, defined as F = N × I (turns × current). A 100-turn relay coil at 10 mA produces 1 A·t; power transformer cores typically operate at 100-1000 A·t. 1 A·t = 1 A (turn is dimensionless in SI).
About Gigaampere-turns
The gigaampere-turn (GA·t) equals 10⁹ A·t. Relevant only in astrophysics - the equivalent MMF of a magnetar neutron star's surface field spans GA·t to TA·t; proposed inertial confinement fusion targets require GA·t-scale pulsed solenoid drives. 1 GA·t = 10⁹ A·t.
