Unit Explanations
SiemensS
Source UnitThe siemens (symbol: S) is the SI unit of electrical conductance, defined as the reciprocal of resistance in ohms. One siemens is equivalent to one ampere per volt, which can be expressed as S = A/V. This unit is used to measure how easily electricity can flow through a material or circuit. The siemens is a derived unit, belonging to the International System of Units (SI), and was adopted in 1960 during the 11th General Conference on Weights and Measures. It is named after the German inventor and electrical engineer Werner von Siemens, who made significant contributions to the development of electrical engineering.
Current Use
Today, the siemens is widely utilized across various industries for measuring electrical conductance. It is an essential unit in electrical engineering, especially in the design and analysis of circuits. The telecommunications industry employs siemens to assess the conductance of transmission lines and cables, ensuring efficient signal transmission. In the field of electronics, components such as resistors, capacitors, and inductors are evaluated using siemens to determine their behavior in circuits. Furthermore, in the realm of materials science, researchers use this unit to characterize the electrical properties of materials, aiding in the development of conductive materials for various applications. Countries worldwide, including the USA, Germany, and Japan, utilize the siemens in both educational and professional settings, reinforcing its importance in global electrical engineering practices.
Fun Fact
The symbol for siemens, 'S', is a tribute to the inventor Werner von Siemens.
Abohm Centimeterab cm
Target UnitThe abohm centimeter is a derived unit of electrical resistance in the centimeter-gram-second (CGS) system, specifically within the electromagnetic system known as the Gaussian system. It quantifies the amount of resistance in a conductor when a current of one abampere passes through it, leading to a potential difference of one abvolt across the conductor. The abohm is equivalent to 10^-9 ohms, emphasizing the unit's utility in contexts where very low resistance measurements are required. The abohm centimeter combines this resistance measurement with a length dimension of one centimeter, further refining its application in precise electrical calculations, particularly in physics and electrical engineering, emphasizing the relevance of dimensional analysis in electrical properties.
Current Use
While the abohm centimeter is not a unit commonly encountered in everyday applications, it plays a significant role in specialized scientific research and electrical engineering. Laboratories that focus on electromagnetic theory, precise resistance measurements, and electrical properties of materials frequently employ this unit to define resistance in contexts where standard SI units might lack the necessary specificity. Countries engaged in advanced electrical engineering research, such as the United States, Germany, and Japan, utilize the unit in academic and industrial settings. The abohm centimeter is particularly useful in fields like condensed matter physics, semiconductor research, and nanotechnology, where understanding minute resistances is critical for developing new technologies and materials. In these contexts, precision measurements in abohm centimeters can affect the design and functionality of electrical components.
Fun Fact
The abohm centimeter is often used in high-precision labs, yet it remains relatively obscure in general use.

electric • SI Unit
Definition
The siemens (symbol: S) is the SI unit of electrical conductance, defined as the reciprocal of resistance in ohms. One siemens is equivalent to one ampere per volt, which can be expressed as S = A/V. This unit is used to measure how easily electricity can flow through a material or circuit. The siemens is a derived unit, belonging to the International System of Units (SI), and was adopted in 1960 during the 11th General Conference on Weights and Measures. It is named after the German inventor and electrical engineer Werner von Siemens, who made significant contributions to the development of electrical engineering.
History & Origin
The concept of electrical conductance dates back to the early experiments with electricity, particularly in the 19th century. The formal definition and measurement of conductance emerged as researchers like Georg Simon Ohm established the relationship between voltage, current, and resistance. Ohm's Law (V = IR) laid the groundwork for understanding electrical circuits. The need for a standardized unit came as electrical systems became more complex, and the importance of conductance in circuit design and analysis increased. The siemens was introduced as a unit of conductance to formalize this aspect of electrical engineering.
Etymology: The term 'siemens' is derived from the name of Werner von Siemens, a prominent figure in the field of electrical engineering, reflecting his significant contributions to the development of electrical systems and technology.

History & Origin
The abohm centimeter traces its origins back to the early 20th century when scientists and engineers began developing the centimeter-gram-second (CGS) system for practical measurements in electromagnetism. The establishment of the electromagnetic unit system allowed for more nuanced and precise measurements of electrical properties, particularly in laboratory settings. The term 'abohm' was specifically coined to represent a unit of resistance in this system, reflecting the need for a standard that could express very small resistances while remaining consistent with the CGS framework. With the adoption of the International System of Units (SI) in later years, the abohm centimeter found its niche in specialized fields requiring these specific measurements.
Etymology: The term 'abohm' combines 'a' from 'absolute' and 'ohm', named after the German physicist Georg Simon Ohm, who formulated Ohm's Law.
