Ampere to Biot Converter

An ampere (A) is the SI base unit of electric current, defined as the flow of one coulomb of electric charge per second. It represents the fundamental measure of electrical current flow in a conductor.

The ampere was named after French physicist André-Marie Ampère in 1881. Originally defined in terms of the force between current-carrying conductors, it was redefined in 2019 based on the elementary charge, providing a more fundamental and precise definition tied to quantum mechanics.

Amperes are universally used for measuring electrical current in all applications, from household electronics to industrial systems. They're essential for electrical safety, circuit design, power calculations, and are found on every electrical device rating, fuse, and circuit breaker.

A biot (Bi) is a unit of electric current in the electromagnetic CGS system, identical to the abampere and equal to 10 amperes in SI units. It was named after French physicist Jean-Baptiste Biot.

The biot was named in honor of Jean-Baptiste Biot, a French physicist who contributed to electromagnetic theory. It was part of the electromagnetic CGS system developed in the late 19th century, designed to simplify electromagnetic equations by eliminating certain conversion factors.

Biots are rarely used in modern applications, appearing mainly in historical electromagnetic literature and some specialized theoretical contexts. Like other CGS electromagnetic units, they've been largely superseded by SI units in all practical and educational applications.
