Nanohenri

Nanohenri is a term that has appeared in speculative discussions of nanoscale electronics and in some science fiction writings as a unit or descriptor for inductive effects at extremely small scales. In established metrology, there is no official unit named nanohenri. The standard SI unit of inductance is the henry, and measurements on the nanoscale are typically expressed in nanohenries (nH), not nanohenri.

Etymology and usage notes that it is not part of the formal vocabulary of physics or engineering. If nanohenri is used in a particular work or theory, its meaning may be defined by that source. In such cases, authors might treat nanohenri as a fictional or provisional unit, or as a general catch-all descriptor for very small inductive interactions in nanoelectronic systems.

Contexts and interpretation vary. Some discussions about nanoscale circuits, quantum inductance, or nanoelectromechanical systems may employ the term as a narrative device or as an informal shorthand. Because there is no universal definition, readers should consult the source material for the exact meaning in a given context. In practical engineering practice, inductance remains measured in henries, with nanoscale values expressed as nanohenries.
