Time is one of the units that hasn't been fully converted to metric, and probably never will be.
Because all time (on earth) is based on natural phenomenon on earth, then it is unlikely that the basic periods of a day, and a year would ever be replaced, and other units (seconds, minutes, hours) would be difficult to change.
Standard units are:
picoseconds
nanoseconds
milliseconds
seconds
minutes
hours
days
years
decades
centuries
millennia
Non standard units might be:
score (20 years)
An Age (if divided equally) is 2,160 years.
A Platonic Year - 25,920 years (time for the procession of the equinoxes)
Also note, there are several different types of years:
The vernal equinox tropical year of about 365.2424 years (varying over the centuries) is used for the Gregorian Calendar.
The mean tropical year of 365.24219 days.
A Sidereal year is 365.256363004 days

The SI unit for time is the second.
The SI unit for time is the second.Other units of time in common use include the minute, the hour, the day, the week, the month, the year, the century, the millennium. A unit of time used in particle physics is the Planck time.
SI unit for time is seconds. Symbol used is "s"
The standard unit that is the same in all systems of units is the second, which is the base unit for measuring time.
The metric units for time are seconds (s), minutes (min), hours (h), days (d), weeks (wk), months (mo), and years (yr).
no one knows it

The standard unit of length is the meter, and any multiple and submultiple such as kilometer and millimeter. Nonstandard units include foot, inch, mile, light-year, parsec, astronomical unit.
You can invent any number of nonstandard units, but none of them is "best". It is best to use standard units, that is, the meter.
The boy was a nonstandard student.
we were using the nonstandard set of measurements
A LOT of places do; it's not just Asia.
The prefix for standard is "non-" as in "nonstandard."
If you mean how many countries have not officially completely changed to the SI units of measure there are 3. The United States, Liberia and Myanmar (Burma).
