Coulombs (C) and millicoulombs (mC) are units of electric charge used to measure the amount of electric charge carried by particles such as electrons and protons. Electric charge is a fundamental property of matter and is responsible for the attraction and repulsion between charged particles.
Coulombs (C)
A coulomb is the SI (International System of Units) unit of electric charge. One coulomb is defined as the amount of charge that flows through a conductor when a current of one ampere (1 A) flows for one second (1 s). In mathematical terms, 1 coulomb equals 1 ampere-second (1 C = 1 A x 1 s).
Millicoulombs (mC)
A millicoulomb (mC) is a subunit of the coulomb and is equal to one-thousandth (1/1000) of a coulomb. It’s often used when dealing with smaller amounts of charge, especially in contexts where the coulomb might be too large a unit to conveniently work with.
How to convert coulombs to mC
1C = 1000mC
or
1mC = 0.001C
Coulombs to millicoulombs conversion formula
Q(mC) = Q(C) × 1000
Example – Convert 3 C to mC
Ans. Q(mC) = 3C × 1000 = 3000mC
