Latitude measure (6)
I believe the answer is:
degree
'latitude measure' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for degree that I've seen before include "Award conferred on a 1 across" , "Academic qualification" , "It's given to college graduates" , "an award at Edinburgh, maybe" , "Award conferred by a college or university" .)
