Unit Explanations
Centimeter-Electric Metercm·A
Source UnitThe cgs e m unit (centimeter-electric meter) is a measurement of electric current based on the centimeter-gram-second (cgs) system of units, which is a metric system of measurements. This unit is defined in terms of the force exerted between two parallel conductors carrying current, specifically, one centimeter apart in a vacuum. The cgs e m unit is equivalent to the current that produces a force of 1 dyne between two infinitely long, straight conductors placed one centimeter apart. Thus, 1 cgs e m unit is defined as 1/10 of an ampere in the International System of Units (SI). This unit emphasizes the fundamental relationships between electric current and mechanical force in electromagnetism.
Current Use
The cgs e m unit is primarily used in scientific and academic research, particularly in fields such as theoretical physics and electromagnetic studies. While it is not commonly employed in everyday applications or industries, its principles are foundational in the understanding of electromagnetism. In countries that utilize the cgs system for certain scientific disciplines, such as parts of Europe and Asia, the cgs e m unit may still be referenced in academic papers and research articles. Additionally, some specialized fields, such as plasma physics and materials science, may occasionally employ this unit when discussing electric currents in relation to mechanical forces.
Fun Fact
The cgs system, including the cgs e m unit, was widely used before the adoption of the SI system.
AmpereA
Target UnitThe ampere, often shortened to amp, is the SI unit of electric current and is defined as the flow of electric charge across a surface at the rate of one coulomb per second. It is one of the seven base SI units and is fundamental to the field of electromagnetism. The ampere is represented by the symbol 'A' and is used to quantify the amount of electric charge flowing through a conductor. Current is a measure of the rate at which charge is transferred, and it is crucial in circuits, devices, and systems that rely on electricity. The ampere can be understood in terms of the force between two parallel conductors carrying current, where one ampere of current produces a specific force between the conductors. This definition is tied to physical constants, making the ampere a precise and essential measurement in electrical engineering and physics.
Current Use
The ampere is widely used in various industries including electrical engineering, electronics, telecommunications, and energy production. It is critical for designing and analyzing electrical circuits, where it helps quantify the flow of electric current. In power generation and distribution, the ampere is essential for determining the load capacity of electrical systems, ensuring that wires and components can handle the current without overheating. In electronics, devices are often rated in amperes to indicate their current consumption, guiding manufacturers in component selection and safety standards. Additionally, the ampere is used in renewable energy sectors, such as solar and wind energy, where it helps in measuring the output of solar panels and wind turbines. Countries around the world adhere to the SI unit of the ampere, and it is crucial in international trade of electrical equipment and components, ensuring compatibility and safety in global markets.
Fun Fact
The ampere is one of the seven base units in the SI system, making it fundamental to all electrical measurements.

Thus, 1 cgs e m unit is defined as 1/10 of an ampere in the International System of Units (SI). This unit emphasizes the fundamental relationships between electric current and mechanical force in electromagnetism.
History & Origin
The centimeter-gram-second (cgs) system originated in the early 19th century as a means to standardize measurements in science and engineering. It was initially developed to provide a coherent system of units based on easily reproducible measurements. The electric units were introduced later as electricity began to play a significant role in science and technology. The cgs system was pivotal for the development of electromagnetic theory, particularly influenced by the work of scientists such as André-Marie Ampère and James Clerk Maxwell.
Etymology: The term 'centimeter' is derived from the Latin 'centum' meaning 'hundred' and 'metrum' from Greek 'metron' meaning 'measure'. The 'e' in e m unit stands for electric.
