How to Convert Millicoulombs to Coulombs

To convert a measurement in millicoulombs to a measurement in coulombs, divide 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:

coulombs = millicoulombs ÷ 1,000

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

For example, here's how to convert 5,000 millicoulombs to coulombs using the formula above.

coulombs = (5,000 mC ÷ 1,000) = 5 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.

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.
