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).
AbvoltabV
Target UnitThe abvolt, symbol abV, is a unit of electric potential in the centimeter-gram-second (CGS) system of units, defined as the potential difference that will produce a current of one abampere through a resistance of one ohm. It is equivalent to 10^-8 volts in the International System of Units (SI). The abvolt is part of the electromagnetic system of units and emphasizes the electromagnetic interactions that take place at a micro scale. As such, it is less commonly used in contemporary scientific work compared to its SI counterparts but remains relevant in certain contexts, especially in fields like astrophysics and historical electric measurements.
Current Use
Though the abvolt has largely been replaced by the volt in most scientific and engineering contexts, it remains a point of reference in specialized fields, such as theoretical physics and certain areas of electrical engineering. In the CGS system, researchers still use the abvolt for calculations that require precision at the micro scale. Countries with significant historical contributions to electromagnetic research, such as the United States and Germany, occasionally utilize the abvolt in educational contexts or in the analysis of historical data. Moreover, niche applications may arise in astrophysics when measuring electric fields in cosmic phenomena, where CGS units can sometimes offer more intuitive understanding of physical interactions.
Fun Fact
The abvolt is one of the lesser-known units in the CGS system, overshadowed by the more widely recognized volt.

Mho
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.
