Convert Abamperes to Picoamperes
Convert Abamperes (abA) to Picoamperes (pA) instantly and accurately.
Conversion Formula
pA = abA × 10000000000000
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 Picoamperes
The picoampere (pA) equals 10⁻¹² A, the standard scale for electrometer measurements, reverse-bias diode leakage, and single ion-channel currents in patch-clamp electrophysiology. A typical open potassium channel carries 1-20 pA; high-quality electrometer inputs resolve below 1 pA; insulation resistance measurements on cables are reported in pA at known voltage. 1 pA = 10⁻³ nA = 10³ fA.
