When to use it

Squared units such as m² and km². In HTML, <sup>2</sup> also works and suits any number.

In HTML, CSS and JavaScript

<p>&sup2;</p>           <!-- or the character itself in a UTF-8 page -->

.note::before { content: "\00B2"; }

const s = "\u00B2";

In a page saved as UTF-8 (the default today) you can paste the character directly; the entity is only needed when it must survive a non-UTF-8 system. Encode or decode whole texts with the HTML Entity Encoder.
