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.
StathenryH₁
Target UnitThe stathenry (symbol: H₁) is a derived unit of inductance in the electromagnetic system of units. It represents a measure of the ability of a conductor to store electrical energy in a magnetic field when an electric current flows through it. Specifically, one stathenry is defined as the inductance that induces an electromotive force (emf) of one volt when the current flowing through it changes at the rate of one ampere per second. This unit is particularly useful in high-frequency applications and specialized electronic circuits where inductance values can be notably large, requiring a more practical scale for measurement and calculation. The stathenry is equal to 10^9 henries, making it a substantial unit, instrumental in understanding inductive reactance and energy storage in electrical systems.
Current Use
The stathenry is primarily used in the fields of electrical engineering, particularly in applications involving high-frequency circuits, such as RF (radio frequency) and microwave engineering. It is commonly encountered in the design and analysis of components such as inductors, transformers, and filters, where inductance values can reach into the billions of henries. Countries with advanced telecommunications industries, such as the United States, Japan, Germany, and South Korea, often utilize the stathenry in their technical standards and specifications for electrical components. Additionally, institutions involved in research and development in electromagnetism and wireless technologies frequently reference the stathenry in academic papers and engineering practices. The use of this unit aids in simplifying discussions and calculations concerning inductive components, facilitating an understanding of their performance in complex electronic systems.
Fun Fact
The henry was named after Joseph Henry, who independently discovered self-induction and mutual induction.

Millihenry
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 stathenry was established in the mid-20th century as the need for larger inductance values became apparent, particularly in the context of radio frequency and microwave engineering. As electronic technologies evolved, the standard henry (H) unit was often too small for practical applications, necessitating the introduction of larger units to simplify calculations and discussions around inductance. The introduction of the stathenry allowed engineers and physicists to work with more manageable figures when dealing with high-frequency circuits and components that exhibit significant inductance. This evolution was driven by the rapid advancements in telecommunications, radar, and microwave technologies, where high inductance values are commonplace, making the stathenry a crucial unit for professionals in these fields.
Etymology: The term 'stathenry' derives from the prefix 'sta-', which suggests something large or substantial, combined with 'henry', named after the American scientist Joseph Henry who made significant contributions to the study of electromagnetism and inductance.
