Unit Explanations
Statmho℧
Source UnitThe statmho (℧) is a unit of electrical conductance in the centimeter-gram-second (CGS) system of units. It is defined as the conductance of a circuit where a potential difference of one statvolt produces a current of one statampere. This unit is derived from the cgs electrostatic system, where the statvolt is defined in terms of the forces between electric charges, and the statampere is derived based on the interaction of charges in a vacuum. The statmho is equivalent to approximately 0.1 siemens, providing a crucial link between different systems of measurement. Conductance describes how easily electric current can flow through a conductor, a fundamental property in electrical engineering and physics.
Current Use
While the statmho is not as commonly used today due to the widespread adoption of the SI units, it still finds application in certain fields, particularly in theoretical physics and electrical engineering. For example, in some areas of electrical research and advanced circuit design, engineers and physicists may revert to CGS units for convenience or historical context. Countries that continue to use CGS units include the United States in specific scientific research realms. Additionally, the statmho is relevant in academic settings where classical electromagnetism is taught, providing students with a historical perspective on electrical units. The unit also appears in literature discussing the historical context of electrical engineering.
Fun Fact
The statmho is not commonly used in modern engineering, making it a historical curiosity.
MicrosiemensμS
Target UnitThe microsiemens (μS) is a derived unit of electrical conductance in the International System of Units (SI), equal to one millionth of a siemens (S). It quantifies the ability of a material to conduct electric current. Conductance is the reciprocal of resistance, expressed mathematically as G = 1/R, where G is conductance in siemens and R is resistance in ohms. This unit is essential in electrical engineering and physics, especially in analyzing circuits and materials.
Current Use
Microsiemens are commonly used to measure the conductance of solutions in various industries, particularly in water quality monitoring and environmental science. For instance, the conductivity of water, which can indicate the presence of dissolved salts or pollutants, is often expressed in microsiemens. This unit is also important in the semiconductor industry for evaluating materials' conductive properties during manufacturing processes.
Fun Fact
The conductivity of pure water is very low, typically around 0.05 μS, making it a poor conductor.

Statmho
electric • Non-SI
Definition
The statmho (℧) is a unit of electrical conductance in the centimeter-gram-second (CGS) system of units. It is defined as the conductance of a circuit where a potential difference of one statvolt produces a current of one statampere. This unit is derived from the cgs electrostatic system, where the statvolt is defined in terms of the forces between electric charges, and the statampere is derived based on the interaction of charges in a vacuum. The statmho is equivalent to approximately 0.1 siemens, providing a crucial link between different systems of measurement. Conductance describes how easily electric current can flow through a conductor, a fundamental property in electrical engineering and physics.
History & Origin
The origin of the statmho can be traced back to the development of the centimeter-gram-second (CGS) system in the 19th century, which was widely adopted for scientific calculations and measurements. This system was established to provide a coherent framework for measuring physical quantities, including electricity. The statmho was introduced as a way to express electrical conductance in a manner consistent with the units used to measure electric charge and potential. The statmho, along with other units in the CGS system, became pivotal in the field of electromagnetism, particularly in the analysis of electric circuits and properties of materials.
Etymology: The term 'statmho' is derived from 'stat' indicating the static electric system and 'mho', which is an inversion of 'ohm', the unit of electrical resistance. The prefix 'stat' in this context refers to the static form of electric charge interactions, as opposed to dynamic systems.

Conductance is the reciprocal of resistance, expressed mathematically as G = 1/R, where G is conductance in siemens and R is resistance in ohms. This unit is essential in electrical engineering and physics, especially in analyzing circuits and materials.
History & Origin
The siemens is named after the German engineer Ernst Werner von Siemens, who contributed significantly to the field of electrical engineering in the 19th century. The microsiemens, as a subunit, emerged as the need for finer measurements in conductance became apparent, particularly in laboratory and industrial applications. Its adoption aligns with the metric system's aim for standardized measurement units across various scientific disciplines.
Etymology: The term 'siemens' is derived from the name of Ernst Werner von Siemens, reflecting his contributions to electrical engineering. The prefix 'micro-' comes from the Greek word 'mikros,' meaning small, indicating a factor of one-millionth.
Current Use
Microsiemens are commonly used to measure the conductance of solutions in various industries, particularly in water quality monitoring and environmental science. For instance, the conductivity of water, which can indicate the presence of dissolved salts or pollutants, is often expressed in microsiemens.
