A footnote says "ISO 31 recommends that the degree be subdivided decimally rather using the >minute and second".Since 1990's I have attempted to revise my old ideas of: The Metric Second (time & arc-angle) - 1973 to *decimalisation of the HOUR in relation to Arc-angle (Degree)*.

*****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! ***** ***** ***** *****

Pat Naughtin in USMA 27361 wrote at length about angle measurement. It would be useful to consider the present situation.
Wild of Heerbrugge, Switzerland, makes theodolites graduAted in gons, grads or grades (chose whichcver name you wish).
"The International System of Units" (SI) lists the radian and steradian as "SI derived units" and the degree, minute and second of angle as "Non-SI units accepted for use with the International System". A footnote says "ISO 31 recommends that the degree be subdivided decimally rather using the minute and second". It does not mention the gon, grad, or grade.
One-third and two-thirds of a right angle are angles that appear frequently in mechanical engineering. With 100 gons to the rightangle these angles are expressed as 33.333... and 66.666..., while in degrees they are 30 and 60. Degrees are universally used in mechanical engineering, cartography, and astronomy. The International System (SI) has not attempted to change them.
