Convert Megaampere to Picoampere
Input the number of megaamperes you want to convert to picoamperes.
How to Convert Megaamperes to Picoamperes
The megaampere and picoampere are both units of electric current. By definition, 1 megaampere equals exactly 1e18 picoamperes. This means to convert megaamperes to picoamperes, you multiply by 1e18.
Formula
Step-by-Step Example
Convert 5 MA to picoamperes:
We need to convert megaamperes to picoamperes
Since 1 MA = 1e18 pA, multiply by 1e18
5 × 1e18 = 5e18
5 MA = 5e18 pA

About These Units
Megaampere (MA)
A megaampere (MA) equals 1,000,000 amperes. Found in fusion reactor plasma currents (ITER: 15 MA), lightning return strokes (peak can exceed 1 MA briefly), electromagnetic launchers, and pulsed power systems. Extreme currents creating enormous magnetic fields.
Picoampere (pA)
A picoampere (pA) equals 10⁻¹² amperes. Used in patch clamp electrophysiology measuring ion channel currents (1-100 pA), electrochemistry, radiation detectors, and precision instrumentation. Single ion channels conduct about 1-10 pA.
