Convert Picoampere-turns to Gigaampere-turns
Convert Picoampere-turns (pA·t) to Gigaampere-turns (GA·t) instantly and accurately.
Conversion Formula
GA·t = pA·t × 1.000000000e-21
About Picoampere-turns
The picoampere-turn (pA·t) equals 10⁻¹² A·t. Relevant in ultra-sensitive flux detection with SQUID magnetometers for magnetoencephalography (MEG), where millikelvin-cooled coils respond to pA·t-level signals from neural currents. 1 pA·t = 10⁻¹² 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.
