34 Ways to calculate the Royal Cubit

Updated versions of the different ways of approximating the cubit. Also includes separate table for Grand Metre (1 plus royal cubit) == 1.5236…. == 1.524.

These are done with pi, phi, e, roots and powers (usually of basic primes), as well as ln, log, sin, cos and tan.

See square roots, cube roots and ln(4) for formulas not shown below.

The Spooky Stuff

To borrow a phrase from Robert Bauval, this falls under the Spooky Stuff category.

It is a very strange connection between the Grand Metre (1 + royal cubit), the base of the natural logarithm ⅇ, and the royal cubit as measured in inches.

Royal cubit, e and inch

I have no explanation for this. It just highlights again the ancient origins of the metre, inch and royal cubit, and how they mysteriously link together with π and ⅇ. But what about φ you ask?…. here you go:

The royal cubit and the stars

There are still some things that bother me about the Royal Cubit, in particular, why did they choose π/6, and why did they use it in preference to the metre.

Something interesting related to the first question has surfaced. Which may just be another random co-incidence like all the others, or maybe not.

First up, a reminder that the Royal Cubit is ⅙ of the circumference of a circle with diameter 1 metre, in other words the arc on a 360/6 = 60° segment, as follows:

Circle, 60 degrees, royal cubit

As you may know, the ancient Egyptians were very fond of their ankh, which looks like this:

Russia Today is a Russian-government aligned/supported news web site. They don’t feature a LOT of stories, but instead focus on major issues (and some sports, particularly wrestling and ice-skating, which seem popular with their readers).

The site is becoming popular as a source of “alt” news, given the high levels of propaganda and fake news emanating out of the Western main-stream media. Being a Russian-government aligned site, they do push the Russian government’s point of view, meaning some people in the west don’t trust them.

Back in the 1970s, during the height of the Cold War Continue reading

Phi redux

I started poking around Giza and ancient Egypt after watching a video on the Nebra disk, and trying to find a similar circle-split-by-phi in the alignments of the Giza pyramids.

I didn’t find what I was looking for at the time (in terms of phi being in the alignment of all three pyramids) but did find lots of other things, including phi between P1 and P3.

In the mean time, the so-called Genetic Disc from Peru came along, and I immediately noticed a similar division there. Here’s the two sides of the disk:

Playing with numbers

Playing around with the great pyramid.

Length of base + height = 440 + 280 = 720 royal cubits.

720/360 = 2 (save this for later)

If we convert to digits by multiplying by 28 (because 28 digits in royal cubit), we get

720 x 28 = 20160

If we divide by 360, we get

20160/360 = 56, which is the number of digits in 2 cubits (see saved value of 2)

As you may know, I’m developing a theory that whoever came up with the cubit system also divided the circle into 336 Zeps. So if we divide by 336 instead….

20160 / 336 = 60

Which is um, all sorts of things, and maybe a hat-tip (or the finger) to the Sumerians and their sexagesimal system.

But what the 60 also equates to, is if you had a wheel of radius 1 metre, then 60 rolls of the wheel would equal the sum of the side and the height.

If your wheel had a diameter of 1 metre (like a chariot), then it would be 120 turns of the wheel. Exactly.
