Abmho per Centimeter [abmho/cm]

The abmho per centimeter (symbol: abmho/cm) is a unit of electrical conductivity in the electromagnetic centimeter-gram-second (CGS-EMU) system of units. The abmho is the CGS-EMU unit of conductance, representing the reciprocal of the abohm (the CGS unit of resistance in the electromagnetic system). When expressed per centimeter, abmho/cm measures the electrical conductivity of a material per unit length.

Electrical conductivity indicates how easily electric current flows through a material — higher conductivity means better conduction. The abmho/cm is used in certain scientific and engineering contexts, particularly within CGS electromagnetic unit systems.

In the International System of Units (SI), electrical conductivity is measured in siemens per meter (S/m). To convert from abmho/cm to siemens per meter, appropriate conversion factors must be applied because CGS-EMU and SI units differ fundamentally.

Though largely replaced by SI units in modern practice, abmho/cm remains relevant in specialized fields, historical references, and theoretical analyses involving electromagnetic units.

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.
