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.
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).
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.
1C = 1000mC
or
1mC = 0.001C
Q(mC) = Q(C) × 1000
Example – Convert 3 C to mC
Ans. Q(mC) = 3C × 1000 = 3000mC
| Charge (coulomb) | Charge (millicoulomb) |
| 0 C | 0 mC |
| 0.001 C | 1 mC |
| 0.01 C | 10 mC |
| 0.1 C | 100 mC |
| 1 C | 1000 mC |
| 10 C | 10000 mC |
| 100 C | 100000 mC |
| 1000 C | 1000000 mC |
To convert Coulombs (C) to Millicoulombs (mC), multiply the value in Coulombs by 1,000.
Formula: 1 C = 1,000 mC.
One Coulomb (C) is equal to 1,000 Millicoulombs (mC).
To convert 0.5 Coulombs to Millicoulombs, multiply by 1,000:
0.5 C = 500 mC.
Yes, a Coulomb is 1,000 times larger than a Millicoulomb.
1 Coulomb = 1,000 Millicoulombs.
Converting Coulombs to Millicoulombs helps when dealing with smaller electrical charges, making it easier to work with measurements in practical scenarios.
