Degrees = (180/pi)*Radians
Multiply the radian measure by 360/2pi
To convert from degrees to radians, you can multiply by (pi / 180). Or use the Excel function to convert from degrees to radians. I am not sure about the name; you can find it under math functions.
Degrees* pi /180
You must multiply that by pi/180, to convert to radians.
radian = 180/2pi degrees
In radian measure, 2pi radians is a full circle. In degrees, 360Â° is a full circle, so 2pi radians = 360Â°. If you want to convert: Radians = (2*pi/360)*Degrees = (pi/180)*degrees. And Degrees = (180/pi)*Radians.
0.3491 radian (rounded)
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.
Just as you can measure a distance in metres and centimetres or in feet and inches, you can measure angles in degrees or radians. You can either set your calculator to radians, or convert from radians to degrees using 1 radian = 180/pi degrees = 57.3 degrees approx or 1 degree = pi/180 radians.
