Convert Femtoampere to Megaampere
Input the number of femtoamperes you want to convert to megaamperes.
How to Convert Femtoamperes to Megaamperes
The femtoampere and megaampere are both units of electric current. By definition, 1 megaampere equals exactly 1e21 femtoamperes. This means to convert femtoamperes to megaamperes, you divide by 1e21.
Formula
Step-by-Step Example
Convert 5 fA to megaamperes:
We need to convert femtoamperes to megaamperes
Since 1 MA = 1e21 fA, divide by 1e21
5 ÷ 1e21 = 5e-21
5 fA = 5e-21 MA

About These Units
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.
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.
