Unit Explanations
HenryH
Source UnitThe henry (H) is the SI unit of inductance, which quantifies the ability of a conductor to store energy in a magnetic field when an electric current flows through it. Specifically, one henry is defined as the inductance of a circuit in which a change in current of one ampere per second induces an electromotive force of one volt. This definition underscores the relationship between current, voltage, and inductance, which is critical in understanding electromagnetic phenomena. The henry serves as a fundamental unit in electrical engineering and physics, particularly in the study of circuits, transformers, and inductors. In practical terms, inductance is crucial for the functioning of various electrical and electronic devices, influencing their performance and efficiency.
Current Use
The henry is widely used in various industries including electronics, electrical engineering, and telecommunications. In electrical engineering, inductors—components that store energy in magnetic fields—are characterized in henries. Devices such as transformers, motors, and generators utilize inductance to function efficiently, making the henry a vital metric in their design and operation. In telecommunications, inductors are used in filters and oscillators to manage signal integrity and frequency response, highlighting the henry's relevance in modern communication systems. Additionally, in the automotive industry, inductance measurements are crucial in the development of electric vehicles, hybrid systems, and advanced driver-assistance systems (ADAS). The henry's application extends globally, with countries such as the United States, members of the European Union, and Japan all employing it in their engineering standards and practices.
Fun Fact
The henry is one of the seven base SI units, underpinning many areas of electrical engineering.
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.

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.
