This page is a redirect. The following categories are used to track and monitor this redirect:
From a cross-project redirect: This is a redirect from a title associated with an item on Wikidata. The Wikidata item associated with this page is femtoampere (Q53679437).
From a related word or phrase: This is a redirect from a word or phrase (term) to a page title that is related in some way. This redirect might be a good search term, or it could be a candidate for a Wiktionary link.
Redirects from related words are not properly redirects from alternative spellings of the same word. They are also different from redirects that are subtopics or related topics, because unlike those, a related word or phrase probably does not warrant its own subtopic section in the target page or possess the possibility of ever becoming an article, template, project page, and so forth.
To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}}instead.
When appropriate, protection levels are automatically sensed, described and categorized.
