How to Convert Amperes to Biots

To convert an ampere measurement to a biot measurement, multiply the electric current by the conversion ratio. One ampere is equal to 0.1 biots, so use this simple formula to convert:

biots = amperes × 0.1

The electric current in biots is equal to the amperes multiplied by 0.1.

For example, here's how to convert 5 amperes to biots using the formula above.
5 A = (5 × 0.1) = 0.5 Bi

Amperes and biots are both units used to measure electric current. Keep reading to learn more about each unit of measure.


The ampere, commonly referred to as just "amp," is the electrical current constant equal to the flow of one coulomb per second. According to an SI brochure, the ampere is a constant current that when passsed through two straight and parallel conductors that are spaced one meter apart, will produce a force equal to 0.0000002 newtons per meter of length.

The ampere is the SI base unit for electric current in the metric system. A ampere is sometimes also referred to as an amp. Amperes can be abbreviated as A, for example 1 ampere can be written as 1 A.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the current in amperes as an expression using resistance and voltage.


The current in amperes is equal to the potential difference in volts divided by the resistance in ohms.


The biot is a unit of electrical current named for Jean-Baptiste Biot. One biot is equal to one abampere.

A biot is sometimes also referred to as an abampere. Biots can be abbreviated as Bi, for example 1 biot can be written as 1 Bi.
