Result in Millicoulombs:

1 C = 1,000 mC

How to Convert Coulombs to Millicoulombs

To convert a measurement in coulombs to a measurement in millicoulombs, multiply the electric charge by the following conversion ratio: 1,000 millicoulombs/coulomb.

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

millicoulombs = coulombs × 1,000

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

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

millicoulombs = (5 C × 1,000) = 5,000 mC

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.

What Is a Coulomb?

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.

What Is a Millicoulomb?

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 thousandths, or 10^-3. Millicoulombs can be abbreviated as mC; for example, 1 millicoulomb can be written as 1 mC.
