Unit Explanations
AbmhoabΩ
Source UnitThe abmho (symbol: abΩ) is a unit of electrical conductance in the centimeter-gram-second (CGS) system of units. It measures how easily electric current flows through a material when a voltage is applied. One abmho is defined as the conductance that allows one ampere of current to flow when one volt is applied across the conductor. The abmho is equivalent to the reciprocal of the abohm, which is a unit of electrical resistance. This relationship is crucial in understanding the behavior of electrical circuits and materials. Given its roots in the CGS system, the abmho is less commonly used today compared to SI units, but it remains relevant in specific contexts related to historical electrical engineering practices and certain scientific calculations.
Current Use
Although the abmho is not widely used in modern applications, it holds historical significance in the study and understanding of electrical engineering principles. It is primarily of interest in academic contexts, particularly when studying the history of electricity and electrical units. In some specialized fields, such as physics and electrical engineering, the abmho may still be used in theoretical discussions or when converting historical data into contemporary units. Countries that utilize the abmho in historical contexts include the United States and the United Kingdom, particularly in academic institutions that focus on the foundations of electrical engineering. In these settings, the abmho serves as a reminder of the evolution of electrical measurement standards and the development of the field itself.
Fun Fact
The abmho is rarely used today, but it was once a standard in electrical engineering education.
AbohmabΩ
Target UnitThe abohm is a unit of electrical resistance in the electromagnetic system of units defined in the centimeter-gram-second (CGS) system. Specifically, it is defined as the resistance through which an electromotive force of one abvolt will cause a current of one abampere to flow. Thus, 1 abohm equals 10^-9 ohms. The abohm is primarily used in contexts where CGS units are prevalent, such as in certain scientific fields and some engineering applications. As a smaller unit of resistance, it is particularly useful for expressing very low resistances, which are common in superconductors and various sensitive electronic components. The abohm is part of the broader electromagnetic system of units, where the relations between electric and magnetic phenomena are described in CGS units.
Current Use
The abohm is primarily used in certain specialized fields of physics and electrical engineering, particularly in contexts where the CGS unit system is still in use. While most modern applications have transitioned to SI units, the abohm can still be encountered in research related to superconductivity, where extremely low resistances are prevalent. Laboratories that conduct experiments in electromagnetism may also utilize the abohm for calculations that require precision in low-resistance measurements. Countries such as the United States and Germany, which have strong research communities in physics and engineering, may still reference the abohm in academic publications or technical papers. The continued existence of the abohm serves to bridge the gap between historical measurement practices and contemporary standards.
Fun Fact
The abohm is named after Georg Simon Ohm, who is famous for formulating Ohm's Law.

Abmho
electric • Non-SI
Definition
The abmho (symbol: abΩ) is a unit of electrical conductance in the centimeter-gram-second (CGS) system of units. It measures how easily electric current flows through a material when a voltage is applied. One abmho is defined as the conductance that allows one ampere of current to flow when one volt is applied across the conductor. The abmho is equivalent to the reciprocal of the abohm, which is a unit of electrical resistance. This relationship is crucial in understanding the behavior of electrical circuits and materials. Given its roots in the CGS system, the abmho is less commonly used today compared to SI units, but it remains relevant in specific contexts related to historical electrical engineering practices and certain scientific calculations.
History & Origin
The abmho was introduced in the late 19th century as part of the CGS system. This was a time when electrical engineering was emerging as a distinct field, and various units were being developed to measure electrical properties. The term 'abmho' was derived from 'mho,' which itself is the reverse spelling of 'ohm,' the unit of resistance. The abmho was devised to facilitate calculations in electrical engineering, particularly in telegraphy and early telecommunication technologies. Its introduction was significant during a period marked by rapid advancements in electrical theory and practice.
Etymology: The name 'abmho' comes from 'ab' which indicates the CGS system, and 'mho,' a term coined in the 1880s to represent conductance, being the reciprocal of resistance.

History & Origin
The abohm originated as part of the centimeter-gram-second (CGS) system, which was developed in the 19th century as a natural progression from earlier measurement systems. The CGS system was widely adopted in scientific research and engineering, particularly in fields related to electromagnetism. With the establishment of the International System of Units (SI) in the mid-20th century, the CGS system began to be phased out, with the ohm becoming the standard unit of resistance. However, the abohm continues to be referenced in specific contexts, particularly in physics and engineering involving low resistance measurements.
Etymology: The term 'abohm' combines the prefix 'a-' from the CGS system, indicating 'absolute' or 'electromagnetic', and 'ohm', named after the German physicist Georg Simon Ohm, who formulated Ohm's Law.
Current Use
The abohm is primarily used in certain specialized fields of physics and electrical engineering, particularly in contexts where the CGS unit system is still in use.
