Convert Abamperes to Nanoamperes
Convert Abamperes (abA) to Nanoamperes (nA) instantly and accurately.
Conversion Formula
nA = abA × 10000000000
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 Nanoamperes
The nanoampere (nA) equals 10⁻⁹ A, typical for reverse saturation currents of silicon diodes, quiescent supply currents of CMOS logic, and microelectrode measurements in analytical electrochemistry. A silicon p-n junction at room temperature has a saturation current of 1-10 nA; a well-designed op-amp input bias current is 1-100 nA; wearable biosensors commonly operate in the nanoampere range. 1 nA = 10⁻³ µA = 10³ pA.
