What is electric charge?

Electric charge is a fundamental property of matter that describes the amount of electric energy present in a particle or object.

Electric charge plays a crucial role in:

  • Physics, being the basis for understanding electromagnetic phenomena, such as Coulomb's law, electric fields, and electric potential. It describes the behavior of particles, atoms, and molecules in electrical and magnetic fields.
  • Electrical engineering for designing, analyzing, and optimizing electrical circuits, devices, and systems. It helps engineers understand the flow of electric current, the behavior of electric fields, and the operation of electrical components, such as capacitors and batteries.
  • Chemistry for studying chemical reactions involving the transfer of electrons, ions, and charge carriers. Chemists use electric charge measurements to understand the electrochemical properties of substances, such as redox reactions, electrolysis, and electroplating.

Electric charge units:

In the International System of Units (SI) electric charge is measured in coulombs (C), named after the French physicist Charles-Augustin de Coulomb. One coulomb is defined as the amount of electric charge transported by a current of one ampere in one second.

Additionally, electric charge can be measured in larger or smaller units, such as:

  • Kilocoulomb (kC) = 1000 coulombs.
  • Megacoulomb (MC) = 1,000,000 coulombs.
  • Millicoulomb (mC) = one thousand of a coulomb.
  • Microcoulomb (µC) = one million of a coulomb.
  • Nanocoulomb (nC) =  one billion of a coulomb.
  • Picocoulomb (pC) = one trillion of a coulomb.

In other systems electric charge is measured in:

  • Abcoulomb (abC): A unit of electric charge in the centimeter-gram-second electromagnetic system of units. 1 abC = 1000 coulombs
  • Ampere-hour (Ah): A unit of electric charge often used in the context of batteries and electrical energy storage.
  • Ampere-minute (Am), Ampere-second (As).
  • Electronic charge (e): The fundamental unit of electric charge carried by a single electron or proton. 1 e = 1.602 x 10^-19 coulombs.
  • Faraday (chem): A unit of electric charge used in chemistry, representing the charge required to electrolyze one mole of ions. It is approximately equal to 96,485.34 coulombs.
  • Faraday (phys): A unit of electric charge used in physics, representing the charge of one mole of electrons. It is approximately equal to 96,485.34 coulombs.
  • Franklin (Fr): A historical unit of electric charge, equivalent to approximately 3.3356 x 10^-10 coulombs.
  • Statcoulomb (statC): A unit of electric charge in the cgs (centimeter-gram-second) electrostatic unit system. 1statC = 3.3356 x 10^-10 coulombs.

Our converter supports conversions between different units of electric charge, which allows you to work with the unit system that is most relevant to your application or preference.
