Amperes to Coulombs per Second Converter

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.

I_A = V_V / R_Ω

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.
