Statmho per Centimeter (statmho/cm)

The statmho per centimeter (statmho/cm) is a unit of electrical conductivity in the electrostatic centimeter-gram-second (CGS) system of units. Here, statmho is the CGS unit of conductance, equivalent to the reciprocal of the statohm (the CGS unit of resistance). When divided by length in centimeters, statmho/cm measures how well a material conducts electricity per unit length.

In simpler terms, electrical conductivity indicates how easily electric current can flow through a material. The higher the conductivity (more statmho/cm), the better the material conducts electricity.

While the statmho/cm is part of the older CGS system, today’s SI system uses siemens per meter (S/m) for conductivity. However, statmho/cm is still useful in certain theoretical and historical contexts, especially in electromagnetic theory and classical physics.

To convert from statmho/cm to siemens per meter, specific conversion factors related to the permittivity of free space and unit scaling are applied, because CGS and SI systems differ fundamentally.

Picosiemens per Meter [pS/m]

Picosiemens per meter (symbol: pS/m) is a unit of electrical conductivity in the International System of Units (SI). It represents one trillionth of a siemens per meter, or

This extremely small unit is used to measure very low conductivity, typically found in highly resistive or nearly insulating materials, such as ultrapure water, gases, plastics, or ceramics. In these cases, standard units like S/m or mS/m are too large to accurately represent such low conductance values.

Electrical conductivity in pS/m is important in fields such as semiconductor research, nanotechnology, material science, and water purification, where even trace amounts of ionic contamination or charge carriers significantly affect performance.

For example, ultrapure deionized water has a conductivity around 5.5 pS/m, indicating extremely low levels of dissolved ions. This is crucial in industries like pharmaceuticals, microelectronics, and nuclear power, where purity is essential.

Using pS/m allows scientists and engineers to quantify and compare extremely low levels of conductivity with precision, supporting the design and evaluation of high-resistance materials and ultra-sensitive systems.
