The Pyramid Inch is a unit of measurement slightly larger than a standard

inch (1.0010846752 British inches or 25.4mm), and is based on the

Royal Cubit, found throughout the pyramids in

Egypt. This

Royal Cubit is slightly longer than 25 standard inches (between 523 mm and 526 mm). Since this length was discovered in many places around the Pyramids, which are obviously works of great skill, it was assumed by some that this Royal Cubit is the natural unit of measurement for length. The

Pyramid foot was also used, which is 307.15

mm, which is very close to 1/100 if an

arc second.

After the

discovery of this, it was found that the

polar radius of

Earth is

approximately 250

million times the length of the Pyramid inch.

Proof indeed! As we have refined the estimate of the polar radius, so have people refined the length of the Pyramid inch, so that correlation is always accurate.

The sides of the

Great Pyramid are approximately

365.25 Royal

Cubits, and the perimeter is 36525 Pyramid Inches. A number which should be familiar to everybody. Some people take this to be another sign of the advanced nature of

Ancient Egypt, others (like myself) wonder why a

burial chamber would need to be in

proportion to both the

polar radius of Earth and to the

length of the year. The pyramid inch is just another of the many

mysteries surrounding the pyramids.
