How to Convert Abamperes to Femtoamperes
The abampere and femtoampere are both units of electric current. By definition, 1 abampere equals exactly 1e16 femtoamperes. This means to convert abamperes to femtoamperes, you multiply by 1e16.
Formula
Step-by-Step Example
Convert 5 abA to femtoamperes:
We need to convert abamperes to femtoamperes
Since 1 abA = 1e16 fA, multiply by 1e16
5 × 1e16 = 5e16
5 abA = 5e16 fA

About These Units
Abampere (abA)
An abampere (abA), also called biot, is the CGS electromagnetic unit of current equal to exactly 10 amperes. Defined so that two parallel wires 1 cm apart carrying 1 abampere each exert 2 dynes per cm of force. One ampere = 0.1 abamperes.
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.
