The reason why the circumference is set at 360 degrees is now more accepted as saying that the ancient Egyptians considered 360 days a year (albeit a matter of fact), and the ancients considered the 360 ​​a world with a simple philosophical unity On the constant, so later in the astronomical observations and measurements of the circumference when the 360 ​​as the circumference of the degree.
