A most interesting topic! I offer that at times 1 liter IS a satisfying unit of measurement for beer. Twist drills don't drill round holes anyway. I have always assumed that the Bible originated the 7 day cycle? I thought the Romans originated the current calendar with a serious adjustment of a couple of missing weeks by a Pope (Gregory?) in the 1700's? Any one standard unit of measurement is insufficient in modern society. The appropriate standard depends on what you are measuring and for what purpose. Would you deny mathematicians and scientists the use of radians because degrees are more popular? The only time the "proper" standard is in question is when more than one standard will works equally well. BTW, I thought there was a full day correction scheduled for the year 2000 between December 31 & January 1. It would be required to correct an accumulated error had the effect moving the seasons forward(backwards?) one day. Was it my imagination? I know it never happened. Perhaps I read too many science fiction novels?
