Convert Megaamperes to Picoamperes
Convert Megaamperes (MA) to Picoamperes (pA) instantly and accurately.
Conversion Formula
pA = MA × 1.000000000e+18
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 Picoamperes
The picoampere (pA) equals 10⁻¹² A, the standard scale for electrometer measurements, reverse-bias diode leakage, and single ion-channel currents in patch-clamp electrophysiology. A typical open potassium channel carries 1-20 pA; high-quality electrometer inputs resolve below 1 pA; insulation resistance measurements on cables are reported in pA at known voltage. 1 pA = 10⁻³ nA = 10³ fA.
