Forty degrees of heat, forty degrees alcohol and an acute angle of forty degrees — why do we measure things completely unrelated to each other in the same value?

Geometric degree is a common value used to measure plane angles, ground coordinates, and azimuth. The circumference is exactly 360 degrees.

Fundamentals of Geometry

Placing an equilateral triangle in a circle, the Sumerians found that a total of six figures fit in a circle. In a regular triangle, each angle is 60 °, therefore, in a circle of them 6 x 60 = 360. The number turned out to be very convenient, because it is divisible by all numbers from 1 to 10, except 7, as well as by 12, 15, 18, 20, etc.

In 1701, a prototype thermometer

Rankin, Delisle, Newton proposed their options. Anders Celsius is best known to us. Through his efforts in 1742, zero

Method to measure the strength of a drink in degrees

Thus, the degree of a drink is its strength, that is, the percentage of pure alcohol. The Hess method and his alcohol meter proved to be the most convenient and were accepted all over the world, only recently giving way to other measurement systems.

The word itself is translated from Latin as «step».

In fact, the word «degree» refers to the number of steps taken away from the conventional standard. With the same success, you can use «degree», «unit» and other similar terms in meaning.

Due to its versatility, the degree has found its way into many languages ​​and sciences. For example, in addition to the strength of alcohol and the angles, this value also measures the density of the liquid, color temperature, phase difference in electrical engineering, and even the acidity of milk.
