Convert Abampere to Milliampere (abA to Milliampere)

Abampere (abA) and Milliampere (Milliampere) are both units of current. With the conversion form below, you can effortlessly and accurately convert abampere to milliampere. This free online calculator tool makes it simple and easy to perform the conversion from abA unit to the Milliampere 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.

An abampere (aA) is a unit of electric current from the CGS electromagnetic system of units. One abampere equals 10 amperes in SI units. The abampere developed as part of the CGS electromagnetic system used in the 19th and early 20th centuries. The unit appears occasionally in historical scientific literature and specialized physics texts, but modern practice has almost entirely replaced CGS units with SI units. Abamperes are rarely encountered in contemporary applications, though some legacy scientific documents and older physics references may use the notation.

A milliampere (mA) is a unit of electric current equal to one thousandth of an ampere (10^-3 amperes). Milliamperes are standard in electronic circuits, consumer electronics, and biomedical devices. Battery chargers, LED circuits, and medical equipment like TENS units operate at milliampere ranges. The milliampere is practical and widely understood in electronics, appearing on device specifications, user manuals, and equipment labels. Battery capacity is often rated in milliampere-hours (mAh), making the unit familiar to anyone using rechargeable devices.
