How To Convert Radians To Degrees and Back This practice in fact was around from 1400 and hence it might be right to suggest that radian has been in use for more than 600 years now. It would be pertinent to mention that the practice of measuring angles using the length of an arc was already in vogue and many other mathematicians were practicing it.

So it might not be wrong to mention that Radians might have come into use from 1714. He understood that it was a natural unit for the purpose of angular measurements. He was able to describe and explain everything pertaining to radian but was not able to name it. The entire concept of radian measure is perhaps the brainchild of Roger Cotes and he discovered it in 1714. Hence today when we talk about radian it is considered as SI derived unit measurement. Formerly this unit was referred to as a supplementary unit, but eventually this was abolished sometime during 1995. To put in other words one radian is roughly equivalent to around 57.3 degrees. According to this measurement the arc length of a unit circle must be equivalent numerically to the radian measurement of the angle which it subtends. Radians are another commonly used and standard unit for measuring and are extensively used in mathematics. It must have been written sometime during the 1500 – 2000 BCE. There are also empirical evidences to suggest that Indian might also have used degrees and it is clearly mentioned in the Rigveda an ancient collection of Hindu Hymns. There are evidences to suggest that the earliest trigonometry which was used by Babylonian astronomers and also their Greek successors made use of Degree as a unit of measurement. Though the exact reason for choosing degree as a unit of angle and rotation is not known there are reasons to believe that it was a part of the sexagesimal numeric system. Hence we will also find out how this can be done. There also would be the need to convert degree to radian and vice-versa. For example when it comes to building homes, building, bridges, roads, railway lines, airports, shipyards and other infrastructure constructions they are very much in use and extremely vital and critical. They are extremely useful in various day to day activities. We will also try and learn about the history pertaining to these geometrical measurement terms which are so commonly. Anyhow we would like to reopen the topic once again and try to understand these terms from a layman’s perspective. We may not have shown much interest about it. If we look back at our school and college days we certainly would have come across terms such as angle and degrees. If you are a student with an inclination and interest towards math and geometry then you will certainly find the next few lines of interest.

Refer to the respective pages for more detail.Edit any of the fields below and get answer: It is also common for the sines and cosines of these angles on a unit circle to be listed. These angles are shown in the circle below. While the conversions above can be used to convert between any radian or degree measure, there are a number of angles in trigonometry that are so frequently used that it is worth memorizing their measures.

The circular black arrow indicates the measure of a full rotation in degrees, and the angle measure in radians is shown in red.īased on this, the relationship between radians and degrees is: 2π radians = 360° In the figure below, the blue ray indicates the terminal side of the angle whose initial side is the positive x-axis. Substituting this into the equation for radian measure, The length of the arc that subtends the central angle of a circle in the case of a full rotation is equal to the circumference of the circle. The circumference, c, of a circle is measured as Where θ is the angle in radians, s is the arc length, and r is the radius of the circle. The measure of a radian is equal to the length of the arc that subtends it divided by the radius, or One full rotation around a circle is equal to 360°. We can derive the relationship between degrees and radians based on one full rotation around a circle. The one on the left is measured in radians and the one on the right is measured in degrees. While many different units have been used to measure angles throughout history, radians and degrees are the most common angle measures used today.īelow are two angles that have the same measure.
