# Is there a “metric system” equivalent for measuring time? [closed]

Just as in the metric system it's easy to convert from one unit of measurement to another using base 10, is there any calendaring system that measures time in an equivalent way?

• In other words, is there a BaseN way of measuring time?

• What is the point of reference for this measurement? (Moon, Earth's orbit, some inter-stellar heartbeat, etc)

I suspect this question may be closed because it's not really a math question, but you may want to see en.wikipedia.org/wiki/Swatch_Internet_Time#Beats – Trevor Wilson Feb 21 '13 at 20:00
I posted here because the rotation of the earth is somewhat a circle, and was hoping for something that relates to pi or Tau. In other words, if math is the underpinning of the universe, and Time aligns with that premise, I want to see the intersection of the concepts. – LamonteCristo Feb 21 '13 at 20:02
Oh, like a unit of time in which the earth rotates by one radian? I think it would be more convenient if the new unit of time were a rational multiple of 1 day :) – Trevor Wilson Feb 21 '13 at 20:03
Also, en.wikipedia.org/wiki/Decimal_time is probably a better reference than my first link. – Trevor Wilson Feb 21 '13 at 20:04
Multiple of 1 day? Awfully imperialistic of you ;) ... isn't that how some other less scientific methods of measurement were created en.wikipedia.org/wiki/Imperial_units – LamonteCristo Feb 21 '13 at 20:05
