Electric Charge Converter
Electric charge is a fundamental property of matter that determines how objects interact with electromagnetic fields. When an object gains or loses electrons, it becomes charged positively or negatively, respectively. Like charges repel each other, while opposite charges attract.
The base unit of electric charge in the SI system is Coulomb (C).
Electric charge plays a crucial role in various scientific and engineering disciplines, including electronics, physics, and electrical engineering. To work with charge in different contexts, we use a variety of charge units. In this article, we will explore and understand these units, along with their conversion factors.
Coulomb (C): The coulomb is the SI unit of electric charge and is defined as the amount of charge transferred by a current of one ampere in one second.
Conversion Factor: 1 C = 1 C (Base Unit)
Kilocoulomb (kC): One kilocoulomb is equal to one thousand coulombs.
Conversion Factor: 1 kC = 1,000 C
Megacoulomb (MC): One megacoulomb is equal to one million coulombs.
Conversion Factor: 1 MC = 1,000,000 C
Millicoulomb (mC): One millicoulomb is equal to one-thousandth of a coulomb.
Conversion Factor: 1 mC = 0.001 C
Microcoulomb (μC): One microcoulomb is equal to one-millionth of a coulomb.
Conversion Factor: 1 μC = 0.000001 C
Ampere-second (A•s): An ampere-second is the product of current in amperes and time in seconds. It is equivalent to coulomb and represents the quantity of charge flowing through a circuit in one second.
Conversion Factor: 1 A•s = 1 C
Ampere-minute (A•min): An ampere-minute is the product of current in amperes and time in minutes.
Conversion Factor: 1 A•min = 60 A•s = 60 C
Ampere-hour (A•h): An ampere-hour is the product of current in amperes and time in hours.
Conversion Factor: 1 A•h = 60 A•min = 3,600 A•s = 3,600 C
Abcoulomb (abC): The abcoulomb or electromagnetic unit of charge (emu of charge) is the derived physical unit of electric charge in the cgs-emu system of units. One abcoulomb is equal to ten coulombs. It is the charge flowing in 1 second given a current of 1 abampere.
Conversion Factor: 1 abC = 10 C
EMU of charge (EMU): Electromagnetic unit of charge is another name for the abcoulomb.
Conversion Factor: 1 EMU = 1 abC = 10 C
ESU of charge (ESU): Electrostatic unit of charge, also known as the statcoulomb, is the charge unit in the cgs (centimeter-gram-second) electrostatic units variant and Gaussian systems of units. It is equal to the quantity of charge transferred in one second across a conductor in which there is a constant current of one statampere.
Conversion Factor: 1 ESU ≈ 3.33564 * 10^-10 C
Statcoulomb (statC): The statcoulomb is another name for the electrostatic unit of charge.
Conversion Factor: 1 statC = 1 ESU ≈ 3.33564 * 10^-10 C
Franklin (Fr): The franklin is another name for the statcoulomb.
Conversion Factor: 1 Fr = 1 statC ≈ 3.33564 * 10^-10 C
Elementary charge (e): The elementary charge is the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e. This elementary charge is a fundamental physical constant.
Conversion Factor: 1 e = 1.60217663 * 10^-19 C
