# What is Sexagesimal measure?

**Sexagesimal**(also known as base 60 or sexagenary) is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, was passed down to the ancient Babylonians, and is still used—in a modified form—for

**measuring**time, angles, and geographic coordinates.

Also asked, what is Sexagesimal system of measurement?

The **sexagesimal system** and its operations. The **sexagesimal system** is a **system** of numeration in which every unit is divided into 60 smaller units. In other words, the base used is 60. This **system** is used to **measure** time and angles.

Similarly, what is centesimal system? In the **centesimal system**, a right angle is divided into 100 **centesimal** degrees; each **centesimal** degree, into 100 **centesimal** minutes; and each **centesimal** minute into 100 **centesimal** seconds. (**Centesimal** degrees are also known as grads, grades, or gon.)

Also to know is, why did Sumerians use base 60?

**Sumerians** used sexagesimal numerals not only because the number **60** has many divisors or it is countable on the fingers of both hands but because **60** is the least common multiple of the number of fingers of both hands and the number of months in a year.

What are the units of angle measurement?

There are three **units** of **measure** for **angles**: revolutions, degrees, and radians. In trigonometry, radians are used most often, but it is important to be able to convert between any of the three **units**.
