Answer:

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 and #39# seconds.

  • lengths - then it means: #'# - feet, #''# - inches like: He is #5'4''# tall. The sentence would mean : He is #5# feet and #4# inches tall. (about 165 cm)
