Why is a minute divided into 60 seconds, an hour into 60 minutes, yet there are only 24 hours in a day?

In today's world, the most widely used numeral system is decimal (base 10), a system that probably originated because it made it easy for humans to count using their fingers. The civilizations that first divided the day into smaller parts, however, used different numeral systems, specifically duodecimal (base 12) and sexagesimal (base 60).

Scientific American explains the case.
