fA = MA × 1.000000000e+21
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 Femtoamperes
The femtoampere (fA) equals 10⁻¹⁵ A, encountered in patch-clamp background noise, advanced CMOS sub-threshold leakage, and electrochemical scanning probe measurements. Individual ion channels in biological membranes produce baseline noise currents of a few femtoamperes; the off-state leakage of a modern 3 nm transistor is well below 1 fA per device. 1 fA = 10⁻³ pA = 10³ aA.
