According to Sir Issac Newton the Great Pyramid was constructed using units of measurement called cubits. But there were two types of cubit measurements, the sacred and the profane. The differences were based upon the study by a man named Greaves derived their difference from measurements in the Kings chamber.

When 20.63 British inches produced a room an even length of cubits:20×10, this measurement computed and established the profane cubit. The sacred cubit, Newton computed, came from Josephus description of the circumference of the pillars of the Jerusalem temple.

The sacred cubit is designated in the form of a horseshoe projection, known as the “Boss” on the face of the Granite Leaf in the Ante-Chamber of the Great Pyramid. By application of this unit of measurement it was discovered to be subdivided into 25 equal parts known now as: Pyramid inches.

Newton estimated this cubit to be between 24.80 and 25.02 British inches, but believed the figure could be refined through further measurements of the Great PYramid and other ancient buildings of the Hebrew pre-monarchy period.

In his research report and recorded as “A dissertation upon the Sacred Cubit,” of the Jews, Newton with John Greaves, and with calculations from the Great Pyramid and from cubit measurements from other nations determined the profane cubit.

But Greaves made inaccurate measurements upon which Newton made his calculations, which were done at the base of the Great Pyramid. This misinformation was due to the debris surrounding the base of the pyramid.
