To convert a measurement in amperes to a measurement in coulombs per second, divide the electric current by the following conversion ratio: 1 amperes/coulomb per second.

Since one coulomb per second is equal to 1 ampere, you can use this simple formula to convert:

coulombs per second = amperes ÷ 1

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

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

How Many Coulombs per Second Are in an Ampere?

There are 1 coulomb per second in an ampere, which is why we use this value in the formula above.

1 A = 1 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.

What Is an Ampere?

The ampere, commonly referred to as an "amp," is the electrical current constant equal to the flow of one coulomb per second.

The ampere was previously defined as a constant current that when passed 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.

In 2019, the ampere was redefined as the electric current corresponding to the flow of 1/(1.602 176 634 × 10-19) elementary charges per second.[1]

The ampere is the SI base unit for electric current in the metric system. An 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.

Amperage and Ohm's Law

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.

IA = VVRΩ

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

What Are 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.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.[2] For example, C/s is expressing a change in electric charge relative to a change in time.
