Unit Explanations
MillihenrymH
Source UnitThe millihenry (mH) is a derived unit of inductance in the International System of Units (SI), representing one thousandth of a henry (H). It quantifies the ability of a conductor to induce electromotive force (EMF) when the current flowing through it changes. Inductance is a fundamental property in electrical engineering and physics, underlying the principles of electromagnetism. The relationship between inductance and magnetic flux linkage is critical in the design of electrical circuits, transformers, and inductors. The millihenry is widely used in various applications where smaller inductance values are required, making it an essential unit in electronics and electrical engineering.
Current Use
The millihenry is widely utilized in various industries, particularly in electronics, telecommunications, and automotive engineering. In circuit design, millihenries are often employed to specify the inductance of inductors and transformers, particularly in applications requiring compact components with precise inductive values. Electronics manufacturers, engineers, and hobbyists rely on millihenries for designing filters, oscillators, and power supplies. Countries such as the United States, Japan, Germany, and South Korea prominently use this unit in educational settings, research, and practical applications. The rise of portable electronics and high-frequency applications has further solidified the importance of millihenries in modern electrical engineering.
Fun Fact
The henry, the base unit of inductance, is named after Joseph Henry, who also discovered self-induction.
ExahenryEH
Target UnitThe exahenry (symbol: EH) is a derived unit of inductance in the International System of Units (SI), representing a value of 10^18 henries. Inductance quantifies the ability of a conductor to store energy in a magnetic field when an electric current flows through it. It is a fundamental property in electrical circuits, particularly in components like inductors and transformers. The henry, the base unit for inductance, honors Joseph Henry, a pioneer in electromagnetism, and serves as the cornerstone for defining larger units such as the exahenry. The exahenry is predominantly used in theoretical physics and advanced electrical engineering, where extremely large inductances are discussed, particularly in contexts involving high-energy systems.
Current Use
The exahenry is primarily used in theoretical and specialized practical applications within the fields of electrical engineering, physics, and technology. While not frequently encountered in everyday applications, the exahenry finds relevance in high-energy systems such as particle accelerators, advanced power generation systems, and large-scale electromagnetic devices. Countries with significant advancements in electrical engineering and research, such as the United States, Germany, and Japan, utilize the exahenry in academic and industrial settings. In these environments, the exahenry serves as a conceptual tool for discussing the inductive properties of complex electrical networks and systems, particularly where conventional units are inadequate.
Fun Fact
The exahenry is one of the largest units of inductance in the SI system, making it rare in practical applications.

inductance • Non-SI
Definition
The millihenry (mH) is a derived unit of inductance in the International System of Units (SI), representing one thousandth of a henry (H). It quantifies the ability of a conductor to induce electromotive force (EMF) when the current flowing through it changes. Inductance is a fundamental property in electrical engineering and physics, underlying the principles of electromagnetism. The relationship between inductance and magnetic flux linkage is critical in the design of electrical circuits, transformers, and inductors. The millihenry is widely used in various applications where smaller inductance values are required, making it an essential unit in electronics and electrical engineering.
History & Origin
The concept of inductance, and consequently units like the henry and its submultiples, emerged from the work of several physicists in the 19th century. Particularly, Joseph Henry, an American scientist, played a pivotal role in the discovery of self-induction and mutual induction. His experiments demonstrated how a change in current in a coil could induce an electromotive force in the same coil or in a nearby coil. This foundational work laid the groundwork for electromagnetic theory and the development of inductive components. The millihenry, as a practical subunit, became widely adopted as electronic components grew smaller and more complex, facilitating its use in modern circuit design.
Etymology: The term 'millihenry' derives from the prefix 'milli-', meaning one thousandth, combined with 'henry', named after Joseph Henry.

History & Origin
The concept of inductance was first introduced in the early 19th century, primarily through the work of physicists such as Michael Faraday and Joseph Henry. Their experiments with electromagnetic induction laid the foundation for understanding how electric currents create magnetic fields. The henry was established as the base unit of inductance in 1861, named after Henry, who independently discovered self-induction. The need for larger units arose as technologies advanced and applications in electrical engineering expanded, leading to the formal acceptance of the exahenry in 1959 as part of a systematic approach to scaling units within the metric system.
