Double Prime (Inches / Seconds) ″

The double prime ″ is the proper symbol for inches, arcseconds, and seconds in geographic coordinates, as in 5′11″ or 74° 0′ 21″ W. In mathematics it marks second derivatives and doubly transformed points, like f″(x). Typewriter-era habits replaced it with a straight double quote, but ″ is the typographically correct choice.

Good to know

Don’t mix it up: It is often confused with the straight double quote " (U+0022) and the curly closing quote ” (U+201D).

Tip: In code and spreadsheets, a straight quote may be required; in prose and product labels, use ″ for inches.

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.
