Convert Abamperes to Attoamperes

Convert Abamperes (abA) to Attoamperes (aA) instantly and accurately.

Conversion Formula

aA = abA × 1.000000000e+19

About Abamperes

The abampere (abA), also called the biot (Bi), equals exactly 10 A - the current unit of the CGS-EMU (electromagnetic) system. Two long parallel wires each carrying 1 abA and separated by 1 cm experience a force of exactly 2 dyn per centimetre; this definition directly parallels the original 1948 SI definition of the ampere. The abampere appears in nineteenth- and early-twentieth-century electrical engineering literature. 1 abA = 1 Bi = 10 A.

About Attoamperes

The attoampere (aA) equals 10⁻¹⁸ A, the scale of single-electron tunnelling currents in quantum devices. Individual electrons tunnelling through a molecular junction or quantum dot produce average currents of order 1-100 aA when measured at sub-microsecond resolution; cryogenic shot-noise electrometers achieve sub-attoampere sensitivity. 1 aA = 10⁻³ fA = 10⁻¹⁸ A.
