A possibly unique case of the equals sign of European usage in a person's name, specifically in a [[double-barreled name]], was by the aviation pioneer [[Alberto Santos-Dumont]], as he is also known not only to have often used a [[double hyphen]] {{char|&#x2E40;}} resembling an equal sign {{char|1==}} between his [[double-barreled name|two surnames]] in place of a hyphen, but also seems to have personally preferred that practice, to display equal respect for his father's French ethnicity and the Brazilian ethnicity of his mother.<ref>{{citation |mode=cs1 |last=Gray |first=Carroll F.|title=The 1906 Santos=Dumont No. 14bis |work=W.W.1 Aero: The Journal of the Early Aeroplane |number=194 |date=November 2006 |page=4}}</ref>

Instead of a double hyphen, the equals sign is sometimes used in [[Japanese language|Japanese]] as a separator between names. In [[Ojibwe language|Ojibwe]], the readily available equals sign on most keyboards is commonly used as a substitute for a double hyphen.

=== Linguistics ===
In linguistic [[interlinear gloss]]es, an equals sign is conventionally used to mark clitic boundaries: the equals sign is placed between the [[clitic]] and the word that the clitic is attached to.<ref>{{Cite web|title = Conventions for interlinear morpheme-by-morpheme glosses|url = https://www.eva.mpg.de/lingua/resources/glossing-rules.php|access-date = 2017-11-20|archive-date = 2019-08-04|archive-url = https://web.archive.org/web/20190804103429/https://www.eva.mpg.de/lingua/resources/glossing-rules.php|url-status = live}}</ref>

===Chemistry===
In [[chemical formula]]s, the two parallel lines denoting a [[double bond]] are commonly rendered using an equals sign (hence, a [[triple bond]] is commonly rendered using a [[triple bar]]).

===LGBT activism===

In recent years, the equals sign has been used to [[LGBT symbols|symbolize]] [[LGBT rights]].

===Telegrams and Telex===
In [[Morse code]] the equals sign is encoded by the letters B (-...) and T (-) run together (-...-).{{citation needed|date=August 2020}} The letters BT stand for Break Text, and are put between paragraphs, or groups of paragraphs in messages sent via [[Telex]],{{citation needed|date=August 2020}} a standardised tele-typewriter. The sign, used to mean Break Text, is given at the end of a [[telegram]] to separate the text of the message from the signature.{{citation needed|date=June 2022}}
