from the first post you made an extract from the second article
'For the remainder of this discussion however, a value of 0.5236 m per Royal Cubit is used as the conversion
factor. This factor was proposed by the French archaeologist, and mathematician, Charles Funk-Hellet. Using
this value, and the modern value for the speed of light (2.9979 x 108 m.s-1), it is possible to convert the speed
of light to Royal Cubit’s per second units as shown in Table 1 below. A conversion is also made for the speed
of light expressed in inches per second.'
This unit 0.5236 is 22/42 and the fundamental unit in my system as it comes from Pi as 22/7.
the unit in decimal notation is 0.523809524
0.523809524 x 7 = 3.6666r 10 barleycorns
0.523809524 x 6 = 22/7
In 14.666r there are 28 units and in 29.3333r there are 56 units and this is the Aubrey circle.
Another funamental unit is 0.027777r (Hugh Franklin) and the x 132 is 10 barleycorns.
I hope this helps with your calcs.
