While on usma discussion list, I had proposed a redefinition of the 'metre' based on *1/100th of the degree* linked to radian. I used the collected data that I had; and updated some working while in June last year.
The mention came in again while discussions with Calndr-L and I uploaded my working for experts to examine:

Although AU is not apart of SI, astronomers and NASA cannot ignore their use, like the micro-gram & milligram in medicine. I shall welcome more views.

*****The New Calendar Rhyme*****
Thirty days in July, September:
April, June, November, December;
All the rest have thirty-one; accepting February alone:
Which hath but twenty-nine, to be (in) fine;
Till leap year gives the whole week READY:
Is it not time to MODIFY or change to make it perennial, Oh Daddy!And make the calendar work with Leap Week Rule! ***** ***** ***** *****

Being an amateur astronomer, I find the AU (Astronomical Unit) quite useful.
It is a unit-independent distance marker that allows for quick comparisons
of the distances of solar system objects. It allows people (even lay
people, where astronomy is concerned) to instantly visualize the distances
of planets, asteroids, and comets from the Sun or Earth.
Earth Mass Units or "e" (comparisons of planetary masses to the Earth's mass
where e = 1) are also used in astronomy. E are used on the Voyager
Interstellar Record that is affixed to each of the two Voyager spacecraft
that are leaving the solar system. The masses of the nine planets in terms
of e are included. An explanation of the magnitude of e (they used
universal constants, but I forget which one or ones) is included in the
binary-language coding on the record. If the spacecraft are found by
intelligent alien civilizations in the distant future, they will be able to
compare the masses of the Earth and our other eight planets to the masses of
their worlds. -- Jason
