13.2 is the number of British inches in a Sachsen foot. This means the foot the Sachsens brought with them to England was either more popular than the English foot or took a long time to die out that 13.2 became a popular number. The British inch for some reason replaced the Sachsen inch sooner. There were 12 Sachsen inches in a Sachsen foot. Maybe because the English inch was equated to the Barley corn which was a common seed.jim @ Nov 23 2017, 08:58 PM wrote: Harold

From Encyclopaedia Britannica 1962 edition p.481I ' 13.2........it was the commonest building foot in medieval England (13.2), and its age is seen by its use as the measure for Silbury hill (13.0)'
How old is Silbury hill?
And for anybody interested in quirkie coincidences this is the mountain from which the material to construct silbury hill was hauled and it's also the mountain on which the Wiltshire white horse was created.

the Saros is 18 years 11 days and 8 hours this is 6585.3333 days. this is on the NASA website.You are not getting away with that one Harold.
I see 6585.3223, but no 0.3333.The Saros arises from a natural harmony between three of the Moon's orbital periods (circa 2000 CE):
Synodic Month (New Moon to New Moon) = 29.530589 days = 29d 12h 44m 03s
Anomalistic Month (perigee to perigee) = 27.554550 days = 27d 13h 18m 33s
Draconic Month (node to node) = 27.212221 days = 27d 05h 05m 36s
One Saros is equal to 223 synodic months. However, 239 anomalistic months and 242 draconic months are also equal to this same period (to within a couple hours)!
223 Synodic Months = 6585.3223 days = 6585d 07h 43m
239 Anomalistic Months = 6585.5375 days = 6585d 12h 54m
242 Draconic Months = 6585.3575 days = 6585d 08h 35m
It was never designed, it was hob-nobbled together haphazardly over time.it leaves many unanswered questions about the design of the imperial system.
A length that is close to the modern metre most likely existed in various cultures throughout history. The British wand was close to the metre and it can be argued that the English yard is close enough to the metre to make a connection.Also the Babylonians used the metre even though the French invented it. Perhaps they asked Queen Elizabeth the first's permission.
No one knows the exact day, but we know an approximate time or era. What we o know is when they didn't exist and imperial units did not exist in Stonehenge times.You can't keep telling us when these units were invented because no one has any idea.
I'm sure it was in some cultures but not all and not in the time of the building of Stonehenge.Read 'The Lost Science of Measuring the Earth' by Heath and Michell. it is based on the foot being a universal unit of very ancient measure.
