Equatorial circumference – in relation to Egyptology

The relation between the measurements of the Earth and the Egyptian pyramids is a theory known as pyramidology. According to some proponents of this theory, the dimensions of the pyramids were somehow linked to the size and shape of the Earth itself. One popular claim in pyramidology is that the dimensions of the Great Pyramid of Giza have mathematical and geometric relationships with the size of the Earth. For example, some proponents of this theory argue that the base perimeter of the pyramid is equal to the circumference of a circle that passes through the north and south poles of the Earth when it is expressed in cubits, an ancient Egyptian unit of measurement.

Proponents of pyramidology also claim that the relationship between the Great Pyramid and the size of the Earth is demonstrated in other ways, including the following:

- The height of the pyramid is said to be exactly 1/4th the length of one side of its base.

- The angle of inclination of the pyramid is claimed to be a match for the latitude of the location where it is built.

- The pyramid's orientation is said to be precisely aligned with the cardinal directions north, south, east, and west. Despite these claims, most experts in archaeology, Egyptology, and other relevant fields reject pyramidology as pseudoscientific, unfounded, and based on false assumptions. There is no objective evidence to support the idea that the dimensions of the pyramids were designed with any intention to relate them to the size and shape of the Earth,
