Electric charge is a fundamental property of matter that causes it to experience electromagnetic force. Charge is measured in coulombs (C) in the SI system. It comes in two types—positive and negative—and is conserved: the total charge in an isolated system never changes. The elementary charge (the charge of a proton) is exactly 1.602176634 × 10⁻¹⁹ C. Charge is the source of electric fields and, when moving, of magnetic fields.

A coulomb (symbol: C) is the SI derived unit of electric charge. It measures the quantity of electric charge transferred by an electric current of one ampere flowing for one second. Coulombs are widely used in physics, electrical engineering, electronics, electrochemistry, and telecommunications to quantify electric charge and analyze the behavior of electrical systems.

One coulomb is equivalent to approximately 6.241509074 × 10¹⁸ elementary charges, such as electrons or protons. The coulomb is closely related to other SI electrical units, including the ampere, volt, farad, and joule, making it fundamental to calculations involving electric current, energy storage, and capacitance.

Coulombs are commonly used to describe the charge stored in batteries and capacitors, the amount of charge flowing through electrical circuits, and the movement of ions in electrochemical processes. As the internationally recognized SI unit of electric charge, the coulomb provides a consistent standard for scientific research, electrical measurements, and engineering applications.

An abcoulomb (symbol: abC), also known as the electromagnetic unit (emu) of electric charge, is a unit of electric charge defined in the centimetre–gram–second (CGS) electromagnetic system of units. Abcoulombs were historically used in electromagnetism before the widespread adoption of the International System of Units (SI). Today, they are mainly encountered in older scientific literature and historical references.

One abcoulomb is equal to 10 coulombs (C), making it significantly larger than the SI unit of electric charge. In the CGS electromagnetic system, the abcoulomb is the amount of charge transported by a current of one abampere flowing for one second.

Although the abcoulomb has largely been replaced by the SI coulomb in modern science and engineering, it remains useful for interpreting historical publications, comparing different measurement systems, and studying the development of electrical units. Understanding the relationship between the abcoulomb and the coulomb is valuable when converting values from older technical documents to modern SI units.
