It may have more than one meaning, but it is usually a unit.
Explanation:
An apostrophe sign can be used in:
-
angles - then it means
' - angular minutes,'' - angular seconds. Example:75^o20'39'' which stands for:75 degrees,20 minutes and39 seconds. -
lengths - then it means:
' - feet,'' - inches like: He is5'4'' tall. The sentence would mean : He is5 feet and4 inches tall. (about 165 cm)
