I do not understand your question. Please check the wording. ( I teach celestial navigation. )
Perhaps you are asking how many kilometers in a degree around the equator?
that would be 2 pi R/360 = 2 pi (6380/360) = 111 km approx
That is about 60 nautical miles,
which is just the way Napoleon wanted it when he defined a nautical mile as a minute of arc (1/60 degree) around the earth.
