coulomb/cubic meter [C/m^3] Unit Converter

Definition of coulomb/cubic meter [C/m^3] unit

Coulomb per cubic meter (C/m³) is the SI-derived unit of volume charge density. It expresses the amount of electric charge, measured in coulombs, contained within or distributed throughout a volume of one cubic meter.

History of coulomb/cubic meter [C/m^3] unit

The coulomb per cubic meter emerged with the development of the modern SI system and the formalization of electrical quantities. The coulomb was named after French physicist Charles-Augustin de Coulomb, whose eighteenth-century experiments established the law of electrostatic force. The meter, rooted in the metric system, supplies the volume dimension. As SI coherent units gained international adoption during the twentieth century, C/m³ became the standard expression for volumetric charge density in physics, engineering, and measurement science across laboratories and practical technologies.

Applications of coulomb/cubic meter [C/m^3] unit

Today, C/m³ is used to describe charge distributed through insulating materials, plasmas, electrolytes, and dielectric media. Engineers use it in capacitor and cable design, semiconductor modeling, electrostatic simulations, and field calculations. For example, a material may possess a volume charge density of 2 C/m³, indicating two coulombs of net charge per cubic meter.
