Unit Explanations
Mho℧
Source UnitThe mho, symbolized as ℧, is a unit of electrical conductance in the International System of Units (SI), defined as the reciprocal of resistance measured in ohms (Ω). One mho is equivalent to one siemens (S), which is the standardized SI unit for conductance. Conductance quantifies how easily electric current can flow through a conductor when a voltage is applied. The relationship between conductance and resistance is given by the formula: G = 1/R, where G is the conductance in mhos and R is the resistance in ohms. Since electrical conductance is a measure of the ability of an object to conduct electric current, the larger the mho value, the better the conductor. Mhos are commonly used in various electrical engineering applications to characterize the conductive properties of materials and components.
Current Use
Today, the mho is utilized primarily in electrical engineering and related fields to describe the conductance of materials and components such as resistors, capacitors, and conductive pathways in circuits. It is particularly relevant in applications involving alternating current (AC) where impedance needs to be assessed. Various industries, including telecommunications, electronics, and power generation, rely on measurements of conductance in mhos for the design and analysis of circuits. Engineers may use this unit to evaluate the performance of electrical components, ensuring they meet required specifications for efficiency and safety. Notably, the mho is still prevalent in educational settings, particularly in physics and engineering courses that cover electrical concepts. In countries like the United States, the mho continues to be a recognized unit, while in many other nations, the siemens has become the dominant terminology. Nevertheless, both units are interchangeable, reflecting a shared understanding of electrical conductance across global engineering practices.
Fun Fact
The mho is one of the few units that is spelled backward (ohm).
Statmho℧
Target 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.

electric • Non-SI
Definition
The mho, symbolized as ℧, is a unit of electrical conductance in the International System of Units (SI), defined as the reciprocal of resistance measured in ohms (Ω). One mho is equivalent to one siemens (S), which is the standardized SI unit for conductance. Conductance quantifies how easily electric current can flow through a conductor when a voltage is applied. The relationship between conductance and resistance is given by the formula: G = 1/R, where G is the conductance in mhos and R is the resistance in ohms. Since electrical conductance is a measure of the ability of an object to conduct electric current, the larger the mho value, the better the conductor. Mhos are commonly used in various electrical engineering applications to characterize the conductive properties of materials and components.
History & Origin
The term 'mho' originated in the late 19th century, emerging from the need to quantify electrical conductance, a concept that became more prominent with advancements in electrical engineering. As electrical systems proliferated, particularly in the development of telegraphy and later, electric power distribution, the measurement of how well a material could conduct electricity became essential. The reciprocal relationship between resistance and conductance was recognized, leading to the introduction of mho as a unit to denote conductance directly. The mho was particularly adopted in the United States and was used alongside other electrical units, facilitating clearer communication of conductance values in engineering.
Etymology: The word 'mho' is derived from 'ohm', the unit of electrical resistance, spelled backward.

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.
