=== Link ===
The link column is the title of the article related to that unit. If the link is preceded with <code>+</code> or <code>*</code>, extra text will be inserted before the link, and the text shown by the link will be adjusted to omit a prefix of "US" or "U.S.", if present. For example, if a unit has the symbol "US gal" (or "U.S. gal"), and if the link is <code><nowiki>+[[Gallon]]</nowiki></code>, then if the symbol is linked, it would appear as "[[United States customary units|US]] [[Gallon|gal]]" ("US" and "gal" link to two different articles). If the link is <code><nowiki>*[[Gallon]]</nowiki></code>, it would appear as "[[United States customary units|U.S.]] [[Gallon|gal]]".

Similarly, if the link is preceded with <code>@</code>, extra text will be inserted before the link, and the text shown by the link will be adjusted to omit a prefix of "imp" or "imperial", if present. For example, if a unit has the symbol "imp gal", and if the link is <code><nowiki>@[[Gallon]]</nowiki></code>, then if the symbol is linked, it would appear as "[[Imperial unit|imp]] [[Gallon|gal]]" ("imp" and "gal" link  two different articles).

The [[#Links|Links]] section defines exceptions for unit codes with an SI prefix, where the linked article is different from that of the base unit.

Pipe characters (<code>|</code>) in a table need to be [[Character encodings in HTML|encoded]]. For example, "<code><nowiki>[[Gallon|gal]]</nowiki></code>" should be entered as "<code><nowiki>[[Gallon&amp;#124;gal]]</nowiki></code>". The script that reads this page replaces each <code>&amp;#124;</code> with <code>|</code>.
