Currently the "second" is the Time Measuring Unit which equals one, (For more information see Wikipedia). The most important equivalence is to change this quantity and bring it to an absolute value of 0.8640 times smaller. Surely the physicists and mathematicians members of the Conférence générale des poids et mesures (CGPM) will find a new definition, new conventions and new references more appropriate to the greatness of the new SECOND base 10.
In order not to have confusion or incorrect references to current names, it is necessary to call the division of the day with: hour new, minute new, according to new.
This new denomination just mentioned of the second and its multiples is obvious but not practical in pronunciation, then we could adopt a new denomination of the three submultiples of the day valid internationally and at the same time short and easy to pronounce by all the peoples of the planet Land.

• KIRI is equivalent to HOUR
• MEC equals MINUTE
• SEK equals SECOND
• DECISEK tenths of SEK
• CENTISEK cents of SEK
• MILLISEK thousandths of SEK

An alternative to these names indicating the division of the day, are the following new names analogous to the other methods of decimal measurement and much more appropriate for this great innovation where the basic unit of time measurement is always the "Second" but the names refer to the subdivision of the average calendar day.

• MIRIASEK = DECIDAY - (Indicates the tenth part of the day equivalent to the HOUR)
• ETTOSEK = MILDAY - (indicates the thousandth part of the day equivalent to the MINUTE)
• SEK = CENTMILSEK - (indicates the one hundred thousandth part of the day equivalent to the SECOND)
• DECISEK = tenths of a second
• CENTISEK = hundredths of a second
• MILLISEK = thousandths of a second
• MICROSEK = millionth of a second

To avoid any confusion in equivalences we will use the new names coined above.
Below are the values ​​and the breakdown of the average calendar day with the two measurements:

• Measurement of the average solar day with the sexagesimal system currently in use.
  1 calendar year = 365gg, 5h, 48m, 46s
  24 HOURS a day
  60 MINUTES every hour
  60 SECONDS every minute
  10 tenths of a second
  100 hundredths of a second
  1000 thousandths of a second
  

• Measurement of the average solar day with the new decimal system.
  1 calendar year = 365gg, 2h, 42m, 20s
  10 KIRI per day
  100 MEC every KIRI
  100 SEK each MEC
  10 tenths of SEK
  100 cents SEK
  1000 thousandths of SEK
  

The absolute values ​ needed to calculate the ratio between the two types of subdivision of the average calendar day (the sexagesimal and the decimal ones) will be the following:

• 1 second equals 1,1574 SEK
  1 minute equals 0,6944 MEC
  1 hour equals 0,4166 KIRI
  Or:
  1 SEK equals 0,8640 second
  1 MEC equals 1,4400 minute
  1 KIRI equals 2,4000 hour
  

These transformation coefficients between the time measurement with the sexagesimal measurement system and the new decimal measurement method are values ​​extrapolated from simple correspondence calculations that will be very useful for starting the new calculation method. Only 4 decimal places have been taken into consideration, but for scientific and astronomical calculations more decimal places will have to be considered.
With this new method of measuring time many habits that have been rooted in man for centuries will need to change. To reduce some of the initial inconveniences of this time measurement, perhaps we could maintain the names of the submultiples of the day with the same names HOURS, MINUTES and SECONDS as currently used even if they represent different absolute values.

It will take a very long period of preparation and adjustment for those producing watches as well as for companies that will have to provide new working hours, and finally for all of us who will have to adapt to consider the daily time in a very different way from the current one.
