Degrees came with the 360 and 365 day year and the birth of the gods and the base 60 system used in sumeria.
Behdet to Syene is 24d 6'North to 31d 30' North.

Also recovered from the temple of Amun, were three ritual stone cubit rods, they each carried the identical inscription, which stated that the overall length of Egypt, from Bhedet in the north to Syene in the south was 106 "atur". (An "atur" was 15,000 royal cubits, a "schoenus" was 12,000 royal cubits, and a "minute of march" was 150 royal cubits, as itinerary distances). The southern boundary of Egypt was taken to be different points for a variety of calculations, often enough, these would be natural features such as the great cataract, at the furthest point south. Then the first cataract as another acceptance of the boundary; also celestial bearings such as the tropic at around 24º. Before 1000 BC, Syene was reckoned as one of the southern limits, at 24º 06', where, at that time, the upper horn of the sun shone perpendicularly down a well only at the summer solstice.

Earth dividied into 60 Parts.
Inturn divided into 60 parts (schoene)
Inturn dividied into 60 parts (stades)
The stade being 100 fathom of 6 feet or 4 common cubit
1 common cubit being 25 fingers (28 less 3)
60 * 60 * 60 * 4 * 25 * 100 = 60 * 60 * 60 * 10,000 (ie predynastic finger value and base 60 system).
106 Itr'r x 15,000 royal cubits x 28 fingers = 44,520,000 =
7.42 degrees.
105 It'r = 7.34 degress
107 It'r = 7.49 degrees
100 It'r = 7 degrees
31.5 - 24.1 =
7.4 degrees.
