Henrys

Henrys may refer to multiple topics, depending on context. As a surname, Henrys is of English origin and derives from the given name Henry, a medieval form that spread into various European languages. The surname is relatively uncommon today but appears in genealogical records across English-speaking countries and parts of Europe. Individuals bearing the name have contributed in fields such as politics, science, arts, and sports, though no single figure defines its usage.

In scientific and technical usage, henry is the SI unit of inductance, symbol H. The unit is named after Joseph Henry, a 19th-century American physicist who studied electromagnetism. The henry measures inductance as the ratio of magnetic flux linkage to current; one henry corresponds to an inductance in which a current changing at one ampere per second would induce one volt of electromotive force. The standard plural is henries.

The form Henrys may also appear when referring to multiple people named Henry in a possessive or editorial context, but it is not the common way to pluralize the given name itself. In general, Henry is used as a given name, while Henrys is more typical of a surname or, occasionally, an informal or historical pluralization in non-technical text.

If you are seeking a specific topic, Henrys could refer to a particular person or family, or to the unit of inductance in technical literature.
