Numbers 60 is used to express the time, one hour equal 60 minutes, one minute equal 60 seconds. Numbers 60 was first used by the Sumerians, so they count in base 60 or also called sexagesimal.
The reason why the number 60 is the number used is the smallest number that can be divided by six first number is: 1,2,3,4,5,6. So we can easily imagine: 1/2 hour = 30 min, 1/3 hour = 20 minutes, 1/4 hour = 15 minutes, and so on. Imagine if one hour = 100 minutes, meaning 1/3 hours = 33.333 minutes? Of course being weird. Mathematically, 60 is the denominator number which is 1,2,3,4,5,6,10,12,15,20,30,60.
At first, the second term in English is known as a "second minute," which means that a small part of an hour. The first section is known as the "prime minute" the same minute as it is known today. The amount of the distribution is fixed on 1/60, ie, there are 60 minutes in an hour and there are 60 seconds in one minute. This may be caused by the influence of Babylonia, which uses few system based on sexagesimal (60 base).
The term itself has been found by the time of the Egyptians in the rotation of the earth as 1/24 of a mean solar day. In 1956, the International Committee for Weights and Measures (CIPM), under a mandate given by the 10th General Conference on Weights and Measures (CGPM) in 1954, outlined in the second period of rotation of the earth around the sun on a epoch, because at that time have realized that the rotation of the earth on its axis is not uniform enough to be used as the standard time. *** [EKA | FROM VARIOUS SOURCES | SEPTI | PIKIRAN RAKYAT 14032013]
