There are several explanations for why the circle is divided into 360 parts.Probably the best explanation is connected with the Babylonians
Many,many centuries ago,large distances were measured in the Babylonian mile.The Babylonian mile equaled about seven of our miles.Because of its length,the time needed to travel the Babylonian mile became a measure of time.One day was said to be twelve Babylonian time – miles.
About one thousand years before Christ,the Babylonians began keeping records of star movements.They needed a way to record how much time passed between the moment they first say a star and then observed it again.They used the Babylonian time – mile as their measure of time.In order to have small units of time,the Babylonians divided their time – mile into thirty parts.The Babylonians believed that each trip around the sky was a circle.One complete trip around the sky,they reasoned,took one day.
You already know that one day was the same as twelve Babylonian time – miles.Since each time – mile was divided into thirty parts,the circle trip around the sky was 12×30,or 360 parts long.That is how there came to be 360 degrees in a circle.

关于一个圆为什么分成360份由很多种说法.也许最好的是那个关于巴比伦的解释.
很久很久以前,人们用Babylonian mile来表示一段很长的距离.一个Babylonian mile相当于现在的7英里.因为它的长度,人们把用于完成一个Babylonian mile的时间用来计量时间.一天叫做一个12个Babylonian time (也就是12个Babylonian mile ).
公元前1000年,巴比伦人开始记录星星的运动.他们需要一种方法去测量他们看见一颗星星到他们再次看到一颗星星的时间.他们最后决定用Babylonian time来测量.为了得到更小单位的时间,他们把Babylonian time分割成30份.巴比伦人认为环绕天空的每次旅行都是一个圆.环绕天空整整一圈需要一天(当然是一天,每天都会看到星星的嘛).
你已经知道了一天就相当于12个Babylonian time/mile.既然每个体time/mile都被分成了30份.那环绕天空一圈的时间就是12*30,即360份的长度.
拿就是360度圆的由来
