Convert Biot to Femtoampere

Enter the number of biots that you want to convert to femtoamperes.

1 Bi (biots) = 1e16 fA (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

femtoamperes = biots × 1e16

Step-by-Step Example

Convert 5 Bi to femtoamperes:

1
Convert 5 Bi to femtoamperes

We need to convert biots to femtoamperes

2
Apply the formula

Since 1 Bi = 1e16 fA, multiply by 1e16

5 × 1e16 = 5e16

Answer

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.
