Prime (Feet / Minutes) ′

The prime ′ is a small slanted stroke used for feet, arcminutes, and minutes in coordinates, as in 40° 26′ 46″. In math it marks derivatives and related variables, such as f′(x) or a point A′ after a transformation. It is often replaced by an apostrophe or straight quote on keyboards, but the true prime is angled and sized for these uses.

Good to know

Don’t mix it up: It is often confused with the apostrophe ’ (U+2019) and straight quote ' (U+0027), which have different shapes and meanings.

Tip: Do not let smart quotes convert primes into curly apostrophes; paste the prime character directly for measurements.

Display: the character itself is always the same code point, but its shape comes from the font on the device showing it. If you see an empty box, the font lacks this glyph—the text is still correct.
