Degrees to Radian and vice versa (1 Viewer)

[nabzilla]

I've kind of forgotten how to convert degrees into radians. Can somebody please help?

I know that pi = 180 degrees and that 2pi=360 degrees.
question is how do you convert any degree into radians? Say for example 200 degrees or 22 degrees.

Degrees to radians is times by pi, divided by 180.
Radians to degrees is times by 180, divided by pi.

edit: so like 200 is 200/180pi = 10/9pi and so on.

oh ok.
wait so wouldnt it be 200pi/180 = 10pi/9?

whoops, yep, I meant (10/9)pi haha. sorry >__o

think of it this way

1pi = 180 degrees

lets just say you wanted to know whats 20 degrees in pi. Now look at the RHD, how do you get from 180 to 20...you would Divide by 180 then multiply by 20. Do this do the 1pi on the LHS

1pi divided by 180 x 20 = 1/9 pi (Ignore the pi while doing this calculation)

haha x jiim its cool.

thanks for the help guys!!

Easy way to remember - ratio:
rad/2pi = deg/360

and so...
rad = 2pi * deg / 360

deg = 360 * rad/2pi

degrees to radians is times by pi, divided by 180.
Radians to degrees is times by 180, divided by pi.

edit: So like 200 is 200/180pi = 10/9pi and so on.
