Charge Units Information

Coulomb (C)

The Coulomb is the SI unit of electric charge. One Coulomb is equal to the charge transported by a constant current of one ampere in one second.

Picocoulomb (pC)

The Picocoulomb is 10⁻¹² of a Coulomb. It's commonly used to measure very small charges in applications like semiconductor devices and electrostatics.

Nanocoulomb (nC)

The Nanocoulomb is 10⁻⁹ of a Coulomb. It's often used in measurements of small static charges and in some electronic applications.

Microcoulomb (μC)

The Microcoulomb is 10⁻⁶ of a Coulomb. This unit is frequently used in capacitor measurements and electrostatic experiments.

Millicoulomb (mC)

The Millicoulomb is 10⁻³ of a Coulomb. It's used in applications involving larger charges like battery capacities and electrostatic discharge.

Electron Charge (e)

The elementary charge (e) is the electric charge carried by a single proton or electron. It's approximately 1.602×10⁻¹⁹ C, the fundamental unit of charge.

Ampere-hour (Ah)

The Ampere-hour is a unit of electric charge commonly used in batteries. One Ah equals 3600 Coulombs (1 A × 1 hour).

A Charge Converter is a tool that converts electric charge measurements between different units, such as Coulombs (C), Ampere-hours (Ah), and elementary charge (e). Electric charge is a fundamental property of matter, crucial in physics, electronics, and electrical engineering.
