Volume Charge Density Converter

Volume charge density, written ρ (rho), is the electric charge per volume of a region: ρ = Q / V. Its SI unit is the coulomb per cubic meter (C/m³). It describes charge spread through a material or a cloud of charged particles, rather than over a surface.

The abcoulomb (abC) is the charge unit of the CGS electromagnetic system, and 1 abC = 10 C.

How to convert volume charge density

Type a value into any field, and every other unit is calculated at once. A volume unit is a length unit cubed, so its factor is cubed too: a meter is 100 cm, so a cubic meter is 100 * 100 * 100 = 1,000,000 cm³. For example, 0.002 C/cm³:

1. In C/m³: multiply by 1,000,000.

   0.002 * 1,000,000 = 2,000 C/m³

2. In abC/cm³: divide by 10.

   0.002 / 10 = 0.0002 abC/cm³
