Metric Time

The one thing that hasn't gone metric is time. There's still 60 seconds per minute, 60 minutes per hour, 24 hours per day, etc.

And for good reason. Metric time just wouldn't work.

The SI unit of time is the second. It's described as:

The second [...] is defined by taking the fixed numerical value of the caesium frequency, ΔνCs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be 9192631770 when expressed in the unit Hz, which is equal to s^−1

Yeah, I don't understand it either.

There is a "metric time" accepted for use with the metric system, minutes, hours, and days which are not considered SI units. French Revolutionary Time divided the day into 10 hours, each with 100 minutes, and each minute with 100 seconds, That resulted in a metric second being a slightly different length than a standard SI second. 

According to Wikipedia:

The [French Revolutionary] calendar consisted of twelve 30-day months, each divided into three 10-day cycles similar to weeks, plus five or six intercalary days at the end to fill out the balance of a solar year. It was designed in part to remove all religious and royalist influences from the calendar, and it was part of a larger attempt at dechristianisation and decimalisation in France.

 I doubt it worked well and the calendar was abolished in 1805 after 12 years of usage.

Our current system of 60 seconds per minute and 60 minutes per hour, 24 hours in a day, etc., is just too ingrained in society. Plus it works, unlike the French Revolutionary Calendar. 

What do you think of "metric time"? Let me know in the comments below.
