Convert Biot to Nanoampere (Bi to nA)

Biot (Bi) and Nanoampere (nA) are both units of current. With the conversion form below, you can effortlessly and accurately convert biot to nanoampere. This free online calculator tool makes it simple and easy to perform the conversion from Bi unit to the nA unit.

Electric current is the rate at which electric charge flows through a conductor. It is measured in amperes (A), the SI base unit named after French physicist André-Marie Ampère. One ampere equals one coulomb of charge passing a point per second (1 A = 1 C/s). Current can flow as direct current (DC)—in a single direction—or as alternating current (AC), which periodically reverses direction and powers most homes and businesses worldwide.

A biot (Bi) is a unit of electric current equal to 10 amperes in SI units, making it identical to the abampere. The unit is named after physicist Jean-Baptiste Biot and was used historically in the CGS electromagnetic system. The biot appears occasionally in historical physics literature, particularly in works discussing magnetism and electromagnetism from the late 19th and early 20th centuries. Modern scientific practice uses SI units (amperes) exclusively, making the biot notation rare in contemporary applications. Researchers reviewing historical scientific works or studying classical electromagnetism in traditional textbooks may encounter biot notation.

A nanoampere (nA) is a unit of electric current equal to one billionth of an ampere (10^-9 amperes). Nanoamperes measure extremely weak electrical phenomena encountered in patch clamp electrophysiology, ion channel research, and specialized scientific instrumentation. Ultra-sensitive detection systems and low-noise laboratory equipment operate at nanoampere sensitivity levels. The unit appears in cutting-edge biomedical research and quantum-scale electrical measurements.
