Millicoulomb to Coulomb Formula

A Millicoulomb (mC) is a submultiple of the SI unit of electric charge, the Coulomb (C). The prefix “milli” signifies one-thousandth ($10^{-3}$). Converting between these units is straightforward:

1 Millicoulomb (mC) = 0.001 Coulombs (C)

To convert mC to C: Divide by 1,000
To convert C to mC: Multiply by 1,000

What is a Millicoulomb?

A Millicoulomb (mC) is equal to one-thousandth of a Coulomb. In practical electronics, Millicoulombs are often used to describe the charge stored in larger electrolytic capacitors or the total charge transferred by small batteries over time.

What is a Coulomb?

The Coulomb (C) is the standard SI unit of electric charge. It is defined as the amount of charge transported by a constant current of one ampere in one second (1C = 1A × 1s). It represents a significant amount of charge; for example, a single Coulomb is approximately $6.242 \times 10^{18}$ times the charge of an electron.

Common Usage Examples:

  • Capacitors: A 1000µF capacitor charged to 10V stores exactly 10 Millicoulombs of charge.
  • Batteries: Smartphone battery capacities are usually listed in mAh (milliamp-hours). 1 mAh is equal to 3.6 Coulombs or 3,600 Millicoulombs.
  • Static Electricity: A typical static shock you feel from a doorknob usually transfers only a few microcoulombs, which is much less than a single Millicoulomb.
