To go from degrees to radians: multiply by, divide by 180. (approximately) To go from radians to degrees: multiply by 180, divide by. degrees: In a half circle there are radians, which is also 180°. Another inheritance of the Babylonians is the division of time into hours, minutes, and seconds, which is also done on a similar scale. Let us see why 1 Radian is equal to 57.2958. Although later, it was shown that it was the Earth that revolved around the Sun and not the other way round, this way of measuring the angles has remained to this day. Type the equal to sign, followed by the word DEGREES and opening. This angle became a unit of measure and was called the degree or angle of a degree. Select the first cell of the column where you want your converted values to appear. To this arc, which corresponds to the course of the Sun following its orbit during a day, was made to correspond an angle, whose apex was the center of our planet. Thus, with each passing day, the Sun ran a part of this path. Calculations indicated that the Sun took exactly 360 days to complete a full turn. At that time, it was thought that the Sun revolved around the Earth. The degree has its origin in Babylon, whose system of numbering was based sixty. Each degree can be divided into minutes and seconds. The Degree is a measure of the plane angles that corresponds to `1//360` of a circumference. It is thus indifferent that this length is expressed in mm, cm, dm or any other unit of measurement. The fact that this unit of measure is dimensionless causes that its calculation does not depend on the unit of measure of the length of the arc and the radius. In general, mathematicians and physicists prefer to use angle measurement in radians because the calculation formulas are simpler when the independent variable `x` in the trigonometric functions of `sin(x)`, `cos(x)` and `tg(x)` is in radians. More concretely, the measure of 1 radian is the amplitude of an angle to the center of a circle, whose respective arc measures the same as the radius of the circle. The Radian corresponds to the ratio of the length of an arc to its radius.
