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, inductorsācomponents that store energy in magnetic fieldsāare 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.
PetahenryP H
Target UnitThe petahenry (P H) is a non-SI unit of inductance, representing one quadrillion henries, or 10^15 H. Inductance measures the ability of a coil or circuit to generate an electromotive force (emf) due to a change in current. It is a fundamental property in electrical circuits, particularly in applications involving magnetic fields and alternating currents. The inductance value signifies how much magnetic flux is produced for a given current change. Petahenrys are rarely encountered in everyday applications but can be relevant in theoretical discussions about large-scale electromagnetic systems or in advanced physics. The unit acknowledges the need for measuring inductance in extraordinarily large systems or frameworks, making it essential in high-energy applications.
Current Use
The petahenry is not frequently used in practical applications due to its vast magnitude but serves a critical role in theoretical and scientific discussions, particularly in advanced fields such as quantum physics, astrophysics, and large-scale electrical engineering projects. In these areas, the petahenry can be relevant when calculating inductance in large superconducting coils or in the design of high-energy particle accelerators. The concept of petahenry may also find use in theoretical models that involve magnetic fields generated by massive structures or during discussions about the inductance of large transformers and their electromagnetic interactions. While most engineering applications operate within the lower bounds of the henry, the petahenry signifies a scale of inductance that is important in understanding the limits of electromagnetic theory and the behavior of systems under extreme conditions. Despite its rarity in everyday usage, the petahenry remains an important concept for researchers and scientists.
Fun Fact
The petahenry is rarely used due to its enormous scale, with most practical applications operating in the microhenry to henry range.

In practical terms, inductance is crucial for the functioning of various electrical and electronic devices, influencing their performance and efficiency.
History & Origin
The unit 'henry' was officially adopted in 1861 during the establishment of the International System of Units (SI). It was named in honor of Joseph Henry, an American scientist who made significant contributions to the understanding of electromagnetism and induction. Henry's pioneering work laid the foundations for many modern electrical technologies and his discoveries regarding self-induction and mutual induction were crucial in the development of the field. His experiments demonstrated how a change in current could induce a magnetic field, which formed the basis for the concept of inductance that the henry quantifies.
Etymology: The term 'henry' is derived from the name of Joseph Henry, reflecting the honor bestowed upon him for his groundbreaking contributions to electromagnetism.

Petahenry
inductance ā¢ Non-SI
Definition
The petahenry (P H) is a non-SI unit of inductance, representing one quadrillion henries, or 10^15 H. Inductance measures the ability of a coil or circuit to generate an electromotive force (emf) due to a change in current. It is a fundamental property in electrical circuits, particularly in applications involving magnetic fields and alternating currents.

The unit acknowledges the need for measuring inductance in extraordinarily large systems or frameworks, making it essential in high-energy applications.
History & Origin
The concept of inductance dates back to the 19th century, emerging from the foundational work of physicists like Michael Faraday and Joseph Henry. In 1831, Faraday discovered electromagnetic induction, which led to the understanding of inductance as a property of circuits. Joseph Henry, independently, researched inductance and created devices that exploited this phenomenon. The henry (H), named after Henry, became the standard unit for inductance as per the International System of Units (SI). The prefix 'peta-' was introduced in the 1970s, aligning with the metric system's expansion to express very large quantities. Thus, the petahenry emerged as a means to quantify inductance in exceptionally large contexts, such as in theoretical physics.
Etymology: The term 'petahenry' combines 'peta-', a metric prefix denoting 10^15, derived from the Greek word 'penta' meaning five, and 'henry', named in honor of Joseph Henry.
