What is metric time and how does it work?

Question

I was learning about this in math class but my teacher had no clue on how metric time works.

Answer 1

Metric time is the measure of time interval using the metric system, which defines the second as the base unit of time, and multiple and submultiple units formed with metric prefixes, such as kiloseconds and milliseconds. It does not define the time of day, as this is defined by various time scales, which may be based upon the metric definition of the second. Other units of time, the minute, hour, and day, are accepted for use with the modernized metric system, but are not part of it.

Although a tenth of a day is a convenient unit for scheduling purposes, it is a rather arbitrary one as the base unit for naming purposes. The most natural base unit is a day. Therefore I propose that the base Metric Time unit be called a day in English and that it be equal to one mean solar day. This should, however, be considered a temporary name for the present purpose of explaining decimilized time in English. Users of other languages should replace it with their word for day, such as Tag, día, jour, יוֹם, or 日.

deciday (dd) = 1/10 day (Metric hour)
centiday (cd) = 1/100 day
milliday (md) = 1/1000 day (Metric minute)
microday (µd) = 1/1000000 day (Metric decisecond)

The "day"s may be omitted for brevity in situations where it is understood that you are referring to time. This gives us the following informal or slang names:


deciday = deci or dez
centiday = centi or cent
milliday = milli or mil
microday = micro or mic (pronounced "mike") or moo (the symbol for micro is µ)

Answer 2

Metric time only works on April 1st.
