Convert Megaamperes to Milliamperes
Convert Megaamperes (MA) to Milliamperes (mA) instantly and accurately.
Conversion Formula
mA = MA × 1000000000
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 Milliamperes
The milliampere (mA) equals 10⁻³ A, the everyday unit in consumer electronics and safety standards. Standard LEDs operate at 5-30 mA; USB 2.0 ports supply up to 500 mA; USB-C fast-charging delivers 3 000-5 000 mA. The milliampere is also the clinically important range for electric shock - ventricular fibrillation threshold is around 100 mA, and 1 mA is the threshold of perception. 1 mA = 10⁻³ A = 10³ µA.
