A whole circle is 360 degrees or 2*pi radians. 360 degrees = 2*pi radians so that 1 degree = pi/180 radians This gives the conversion factor of pi/180 to convert degrees to radians.
Two equations, solve for x1°= x radians90° = π/2 radians1/90 = x/(π/2)π/2 = 90xx = π/180 ~= 0.01745 radiansTherefore: 1°= π/180 radians ~= 0.01745 radiansor easier to remember: 180° = π radiansSwitching the equation around:1 radian = (180/π)° ~= 57.2958°
It is an old convention where everything is perfect like a circle, and each year have 360 days (for some reason). The ancients decided to make the unit to measure angles using this system, defining the angle of a full rotation is the godly number 360, and then split down. Now, a more useful and intuitive definition is given, called a radian measure. Where the radian measure of a full rotation as the circumference of the UNIT CIRCLE (circle with radius 1), which is 2 pi.
It is an angle whose measure is 1/180th of a turn,

In radian measure, 2pi radians is a full circle. In degrees, 360° is a full circle, so 2pi radians = 360°. If you want to convert: Radians = (2*pi/360)*Degrees = (pi/180)*degrees. And Degrees = (180/pi)*Radians.
1 revolution = 2pi radians therefore; 1 radian = 1revolution/2 pi radians = 0.159154943 revolution
You want to change radian to degrees. To change radian to degree, multiply the radian by 180 and divide by PI, where PI=3.14159. For example 2 radians = 2 (180)/3.14159 = 114.59 degrees.
180 degrees = 1 pi radian. That means that there are 2 pi radians in a circle. Divide the number of degrees by 180 and you get the pi radians. You can also multiply the pi radians by 180 and get the number of degrees.
A whole circle is 360 degrees or 2*pi radians. 360 degrees = 2*pi radians so that 1 degree = pi/180 radians This gives the conversion factor of pi/180 to convert degrees to radians.
270 degrees, 3π/2 radian
None. A radian is a measure of angular separation in 1-dimensional space, a steradian is a measure in 2-dimensional space. It makes no sense to try to convert from one to the other.
Both are measurements of angular displacement. A degree is 1/360 of a full trun or whole circle. A radian is 1/(2*pi) of a full turn.
"Radian" is a distance. "Revolution per minute" is a speed. Those two units measure different quantities, and they don't convert into each other. It'll help to know that 1 revolution is (2 pi) radians. So "one revolution per minute" is "2 pi radians per minute", etc.

360o = 2*pi*radians or 180o = pi*radiansConvert 7*pi/15 radians to degrees1 radian = 180o/piTherefore: 7*pi/15 radians = 7*pi/15*180/pi = 84 degreesConvert 84 degrees to radians1o = pi/180 radianTherefore: 84o = 84*pi/180 radians = 7*pi/15 radians.Hint: pi always in radian and 180 always in degree. They are equivalents (not equal) to each other.To convert from radians into degree, first erase radian by dividing the given value by pi radian and then multiply the ratio got by 180 deg.Same way to convert from degree into radian, first erase degree by dividing the given value by 180 and then multiply the ratio got by pi radian.So interesting! Is it not?
