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.
PicohenrypH
Target UnitThe picohenry (pH) is a unit of measurement for inductance, defined as one trillionth (10^-12) of a henry (H). Inductance is a property of an electrical circuit that opposes changes in current, and is fundamentally linked to the magnetic fields produced by electric currents. The henry itself is a derived SI unit, named after American inventor Joseph Henry, and signifies the inductance of a circuit in which a change in electric current of one ampere per second induces an electromotive force of one volt. The picohenry is widely utilized in high-frequency applications, where inductances are typically very small, such as in microelectronics and radio frequency (RF) circuits.
Current Use
In contemporary electrical engineering, the picohenry is widely used in the design and analysis of circuits, particularly in applications that involve high frequencies where inductances are minimal. This includes telecommunications, radio frequency (RF) design, and microelectronics, where components such as inductors and transformers are designed to operate at picohenry levels. The picohenry is essential for ensuring the efficiency and performance of integrated circuits, particularly in applications involving signal processing and high-speed data transmission. In countries like the United States, Japan, and members of the European Union, the picohenry is a standard unit in both academic research and practical engineering applications, highlighting its global significance in the field.
Fun Fact
The picohenry is so small that it is often used in nanotechnology and microelectronics.

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.
