Convert Biot to Femtoampere
Enter the number of biots that you want to convert to femtoamperes.
How to Convert Biots to Femtoamperes
The biot and femtoampere are both units of electric current. By definition, 1 biot equals exactly 1e16 femtoamperes. This means to convert biots to femtoamperes, you multiply by 1e16.
Formula
Step-by-Step Example
Convert 5 Bi to femtoamperes:
We need to convert biots to femtoamperes
Since 1 Bi = 1e16 fA, multiply by 1e16
5 × 1e16 = 5e16
5 Bi = 5e16 fA

About These Units
Biot (Bi)
The biot (Bi) is identical to the abampere, equal to 10 amperes. Named after French physicist Jean-Baptiste Biot who studied electromagnetism. Used in the CGS electromagnetic system. One ampere equals 0.1 biots. Rarely used today.
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.
