Biot to Milliampere Converter

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 Like other CGS electromagnetic units, they've been largely superseded by SI units in all practical and educational applications.

A milliampere (mA) is a unit of electric current equal to one thousandth of an ampere. It represents small current levels typically found in electronic circuits, sensors, and low-power devices.

The milliampere became important with the development of electronics and precision electrical measurements in the early 20th century. It provided a convenient scale for measuring currents in radio circuits, early computers, and electronic instruments where currents were much smaller than those in power applications.

Milliamperes are extensively used in electronics, medical devices, sensors, and low-power circuits. They're standard for measuring current consumption in smartphones, LED circuits, biomedical sensors, and electronic control systems. Most electronic specifications use milliamperes.
