Convert Megaamperes to Microamperes
Convert Megaamperes (MA) to Microamperes (µA) instantly and accurately.
Conversion Formula
µA = MA × 1000000000000
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 Microamperes
The microampere (µA) equals 10⁻⁶ A, common in low-power sensor circuits, analogue signal conditioning, and bioelectrical measurement. Surface ECG electrodes record body currents of 1-100 µA; a 1 mW signal at 5 V draws 200 µA; modern low-power microcontrollers sleep at 1-10 µA, enabling coin-cell operation for months or years. 1 µA = 10⁻³ mA = 10³ nA.
