How to Convert Amperes to Coulombs Per Second

To convert an ampere measurement to a coulomb per second measurement, multiply the electric current by the conversion ratio. One ampere is equal to 1 coulomb per second, so use this simple formula to convert:

coulombs per second = amperes × 1

The electric current in coulombs per second is equal to the amperes multiplied by 1.

For example, here's how to convert 5 amperes to coulombs per second using the formula above.
5 A = (5 × 1) = 5 C/s

Amperes and coulombs per second 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.

Coulombs Per Second

One coulomb per second is equal to one coulomb of charge over one second.

Coulombs per second can be abbreviated as C/s, for example 1 coulomb per second can be written as 1 C/s.
