Ampere to Nanoampere 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 nanoampere (nA) is a unit of electric current equal to one billionth of an ampere. It represents extremely small current levels found in advanced semiconductor devices, biological research, and precision measurement instruments.

The nanoampere became important with the development of advanced semiconductor technology and precision biological measurements in the late 20th century. It was essential for characterizing modern transistors, studying cellular electrical activity, and measuring ultra-low currents in research applications.

Nanoamperes are used in advanced semiconductor characterization, biological research, precision instrumentation, and nanotechnology. They're critical for measuring currents in modern transistors, studying ion channels in cells, and characterizing ultra-low-power electronic devices.
