Abmho per Meter [abmho/m]

The abmho per meter (symbol: abmho/m) is a unit of electrical conductivity in the CGS-EMU (centimeter-gram-second, electromagnetic) system. It represents how well a material conducts electric current per unit length. The abmho is the CGS-EMU unit of electrical conductance and is the reciprocal of the abohm, the unit of resistance.

Although the abmho/m is a theoretically valid unit, it is rarely used in practice, especially since the SI (International System of Units) has become the global standard. In the SI system, electrical conductivity is expressed in siemens per meter (S/m).

Conversion to SI:

This means that one abmho per meter equals one billion siemens per meter, making it an extremely large unit compared to those typically used in real-world materials, where conductivities are usually in the range of 10⁻⁶ to 10⁶ S/m.

Use Cases:

While not used in modern electrical engineering, abmho/m might appear in theoretical physics, historical scientific literature, or academic discussions comparing unit systems like CGS and SI.

Mho per Centimeter [mho/cm]

Mho per centimeter (symbol: mho/cm) is a non-SI unit used to measure electrical conductivity, indicating how easily electric current flows through a material per centimeter of length. The term “mho” (which is “ohm” spelled backward) represents the reciprocal of electrical resistance, and is equivalent to the modern siemens (S). Therefore, 1 mho/cm = 1 siemens per centimeter (S/cm).

This unit is often used in electrochemistry, water quality testing, and older scientific literature to describe the conductivity of liquids such as saltwater or electrolyte solutions. Materials with high conductivity (high mho/cm) allow electric current to pass through them easily, while those with low values are poor conductors.

In SI units, electrical conductivity is measured in siemens per meter (S/m). To convert:

Although "mho" has been officially replaced by "siemens", it is still informally used, especially among engineers and in legacy systems. Understanding mho/cm is important when dealing with older data, laboratory instruments, or specific scientific fields where this unit remains in use.
