Charge Converter

Analyzing battery capacity or working on a complex electromagnetic field calculation? Our Free Universal Electric Charge Converter is the most complete tool available online in 2026. Electric charge ($Q$) is a fundamental physical property, and depending on your field—be it electrochemistry, consumer electronics, or theoretical physics—you may encounter vastly different units.

Whether you need to convert Milliampere-hours (mAh) for a smartphone battery, Coulombs (C) for a physics lab, or Abcoulombs (abC) for electromagnetic research, our tool provides 100% accurate results across all 17 parameters.

What is an Abcoulomb (abC)?

The Abcoulomb is part of the electromagnetic (EMU) system of units. One abcoulomb is exactly equal to 10 Coulombs. It is defined as the charge that passes a point in one second when the current is one abampere.

Is a Franklin (Fr) different from a Statcoulomb (statC)?

No, they are two names for the same unit. Named after Benjamin Franklin, it is the base unit of charge in the CGS (centimeter-gram-second) system.

Why do I need to convert "Elementary Charge"?

In particle physics and chemistry, the Elementary Charge (e) is the electrical charge carried by a single proton (or the negative of the charge of an electron). 1\ Coulomb$ is approximately 6.242 \times 10^{18} elementary charges.

How is Ampere-hour related to a Coulomb?

1\ Ah is the charge of 1\ Ampere flowing for 3,600\ seconds. Therefore, 1\ Ah = 3,600\ Coulombs. Our tool makes this conversion instant.

When is a Faraday (F) used?

The Faraday constant is used primarily in electrochemistry to relate the amount of chemical substance consumed or produced in an electrolytic cell to the total electric charge.
