About Gilberts
The gilbert (Gb) equals exactly 10/(4π) A·t ≈ 0.7958 A·t, the CGS unit of magnetomotive force named after William Gilbert (1544-1603). Widely used in older relay and electromagnet datasheets; 1 Gb = 1 oersted·centimetre. 1 Gb = 10/(4π) A·t.
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.
