That means that 1 radian is equal to 180 degrees divided by π. So, in order to convert radians to degrees, all you have to do is multiply the number of radians by 180 divided by π. For instance, let’s say you have to convert 1/2 π radians into degrees. Simply multiply π/2 by 180/ π to get 90 degrees.

these are two units named degrees and radians for measuring the angles. circle contains 360 degrees which are equivalent to 2π radians. by reading this article, you can easily convert radians into degrees measure, or from degrees to radians.

Degree

a degree is referred to as the degree of arc is the unit of measuring a plane angle. its symbol is (°). a circle contains 360°, the angle measure for a complete rotation. A complete rotation is denoted by the angle measuring 360° and the instrument used to measure an angle in degrees is known as the protractor.

Radians

Radian is a unit of measuring an angle in geometry. One radian is the angle, is formed at the center of a circle by an arc whose length is equal to the radius ‘r’ of the circle. A complete clockwise rotation is equal to 2π in the radians of a circle. a right angle is expressed as π/2 radians which are 90°, and a straight angle is expressed as π radians or 180°.

Radians To Degree Measure:

The measure of an angle is determined by the rotation from the initial side to the terminal side. In radians, one complete counterclockwise revolution is 2π, and in degrees is 360° So, degree measure and radian measure are related by the equations

360°=2π radians and

180°=π radians

Formula of degrees to radian Measure:

to convert degrees into radians, we multiply the angle (degrees) by π / 180.

Radians = Degrees × π / 180

Formula of radians to degree Measure:

to convert radians into degrees, we multiply the angle (radians) by 180 /π.

Degrees = Radians × (180/π)

45 degrees in radians:

To convert degrees to radians, multiply by π / 180, since a full circle is 360 degrees or 2π in the radians. 45 degrees is 1/8 of a circle, so 45 degrees = 2 * pi / 8 or approximately 2 * 3.1416 / 8 = 0.786 radians. to convert, multiply the given number of degrees, in this case, 45°, by the conversion factor of π radians/180° as follows:

Given, 45 degrees is the angle

Angle in radian = Angle in degree x (π/180)

Radians = 45° × π / 180

= π / 4 (Radians)

= 0.786 radians

Convert 90 degrees to radians

Given, 90 degrees is the angle

Angle in radian = Angle in degree x (π/180)

= 90 x (π/180)

= π/2

30 degrees to radians

We convert degrees to radian by multiplying 30° by π / 180.

Formula:

Angle in radian = Angle in degree x (π/180)

= 30 × π / 180

= π / 6 (radians)

= 0.167π radians

= 0.52438 radians

Examples of conversion of radians into degrees Measure

Convert π/6 into degrees

Using the formula, Degrees = Radians × (180/π)

π/6 × (180/π) = 180/6 = 30 degrees

Convert π/4 into degrees

Using the formula, Degrees = Radians × (180/π)

π/4 × (180/π) = 180/4 = 45 degrees
