Convert Ampere to Biot (A to Biot)

Ampere (A) and Biot (Biot) are both units of current. With the conversion form below, you can effortlessly and accurately convert ampere to biot. This free online calculator tool makes it simple and easy to perform the conversion from A unit to the Biot 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 ampere (symbol: A), commonly called an amp, is the SI base unit of electric current. It measures the rate at which electric charge flows through a conductor. Amperes are widely used in electrical engineering, electronics, telecommunications, power generation, and industrial systems to quantify electric current in circuits and electrical equipment.

One ampere is defined as the flow of one coulomb of electric charge per second (1 C/s). This relationship makes the ampere one of the fundamental units of the International System of Units (SI), linking electric current with other electrical quantities such as voltage, resistance, power, and electric charge.

Amperes are commonly used to specify the current drawn by household appliances, electric motors, batteries, generators, electronic devices, and power distribution systems. Understanding current measured in amperes helps engineers, electricians, and consumers select appropriate wiring, circuit protection, and electrical equipment for safe and efficient operation.

A biot (Bi) is a unit of electric current equal to 10 amperes in SI units, making it identical to the abampere. The unit is named after physicist Jean-Baptiste Biot and was used historically in the CGS electromagnetic system. The biot appears occasionally in historical physics literature, particularly in works discussing magnetism and electromagnetism from the late 19th and early 20th centuries. Modern scientific practice uses SI units (amperes) exclusively, making the biot notation rare in contemporary applications. Researchers reviewing historical scientific works or studying classical electromagnetism in traditional textbooks may encounter biot notation.
