Why is there 60 second is a minute not 100?

Answer 1

The Babylonians who invented the units of time, and the Greeks who invented

the units of angles, divided the hours, minutes, and seconds of time and the

degrees, minutes, and seconds of angles, into 60 parts, rather than 100 parts,

to make it easier to define sub-parts of them.

You can cut an hour into 2, 3, 4, 5, 6, 10, 12, 15, 20, or 30 equal pieces without

ever cutting up a minute.

If the hour were 100 minutes, your choices would be 2, 4, 5, 10, 20, and 50 parts

without the use of fractional minutes.

A system of decimal time was once introduced, with 10 hours in a day, 100 minutes

in an hour, and 100 seconds in a minute. The reason you haven't heard of it is that

it never caught on.
