How to Convert Milliamperes to Coulombs Per Second

To convert a milliampere measurement to a coulomb per second measurement, divide the electric current by the conversion ratio.

Since one coulomb per second is equal to 1,000 milliamperes, you can use this simple formula to convert:

coulombs per second = milliamperes ÷ 1,000

The electric current in coulombs per second is equal to the milliamperes divided by 1,000.

For example, here's how to convert 500 milliamperes to coulombs per second using the formula above.
500 mA = (500 ÷ 1,000) = 0.5 C/s

Milliamperes and coulombs per second are both units used to measure electric current. Keep reading to learn more about each unit of measure.


One milliampere is equal to 1/1,000 of an ampere, which is the electrical current equal to the flow of one coulomb per second.

The milliampere is a multiple of the ampere, which is the SI base unit for electric current. In the metric system, "milli" is the prefix for 10-3. A milliampere is sometimes also referred to as a milliamp. Milliamperes can be abbreviated as mA; for example, 1 milliampere can be written as 1 mA.

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 formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.[1]
