## How to Convert Coulombs to Millicoulombs

To convert a coulomb measurement to a millicoulomb measurement, multiply the electric charge by the conversion ratio.

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

The electric charge in millicoulombs is equal to the coulombs multiplied by 1,000.

**For example,**here's how to convert 5 coulombs to millicoulombs using the formula above.

### How Many Millicoulombs are in a Coulomb?

There are **1,000** millicoulombs in a coulomb, which is why we use this value in the formula above.

1 C = 1,000 mC

Coulombs and millicoulombs are both units used to measure electric charge. Keep reading to learn more about each unit of measure.

## Coulombs

One coulomb is the electric charge equal to one ampere of current over one second.^{[1]}

The coulomb can be expressed as Q_{C} = I_{A} × t_{s}

The charge in coulombs is equal to the current in amperes times the time in seconds.

The coulomb is the SI derived unit for electric charge in the metric system. Coulombs can be abbreviated as *C*; for example, 1 coulomb can be written as 1 C.

## Millicoulombs

The millicoulomb is 1/1,000 of a coulomb, which is the electric charge equal to one ampere of current over one second.

The millicoulomb is a multiple of the coulomb, which is the SI derived unit for electric charge. In the metric system, "milli" is the prefix for 10^{-3}. Millicoulombs can be abbreviated as *mC*; for example, 1 millicoulomb can be written as 1 mC.
