Abampere to Microampere Converter

An abampere (abA), also called a biot, is a unit of electric current in the electromagnetic CGS system, equal to 10 amperes in SI units. It was defined based on the magnetic force between current-carrying conductors.

The abampere was developed as part of the electromagnetic CGS unit system in the late 19th century by physicists working on electromagnetic theory. It was designed to make electromagnetic equations simpler by eliminating certain constants, though it resulted in unfamiliar unit sizes.

Abamperes are rarely used in modern applications, appearing mainly in historical scientific literature and some specialized electromagnetic theory contexts. They've been largely replaced by SI units (amperes) in all practical applications and modern scientific work.

A microampere (μA) is a unit of electric current equal to one millionth of an ampere. It represents very small current levels found in precision electronics, biological systems, and ultra-low-power devices.

The microampere became necessary with the advancement of precision electronics and biological measurements in the mid-20th century. It was particularly important for measuring currents in transistors, integrated circuits, and biological systems where currents are extremely small.

Microamperes are used in precision electronics, biomedical measurements, semiconductor testing, and ultra-low-power devices. They're essential for measuring leakage currents, biological signals (like nerve impulses), and current consumption in battery-powered devices and IoT sensors.
