Convert Megaampere to Femtoampere
Type the number of megaamperes that you wish to convert to femtoamperes.
How to Convert Megaamperes to Femtoamperes
The megaampere and femtoampere are both units of electric current. By definition, 1 megaampere equals exactly 1e21 femtoamperes. This means to convert megaamperes to femtoamperes, you multiply by 1e21.
Formula
Step-by-Step Example
Convert 5 MA to femtoamperes:
We need to convert megaamperes to femtoamperes
Since 1 MA = 1e21 fA, multiply by 1e21
5 × 1e21 = 5e21
5 MA = 5e21 fA

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.
Femtoampere (fA)
A femtoampere (fA) equals 10⁻¹⁵ amperes or about 6,242 electrons per second. Used in quantum devices, single-electron transistors, and cutting-edge neuroscience. The current from a single electron per second is 0.16 fA. Requires specialized low-noise amplifiers.
