Thread: revs to rads

Hi:
I am trying to convert revolutions to radians.
90rev/s X 2pie/1rev
so i can cancel the revs leaving 90 X 2pie/s
now, I get 565.4866776rad/s
but apparently I should get 283rad/s. Which is half of what I get.

help!

Hello, lemonz!

I am trying to convert revolutions to radians.

. . $\displaystyle \frac{90\text{ rev}}{1\text{sec}} \times \frac{2\pi\text{ radians}}{1\text{ rev}} \:=\:180\pi\text{ rad/sec} \:\approx\:565.5\text{ rad/sec}$


but apparently I should get 283 rad/sec. . They are wrong!

You are right!

hmmm!
well that is curious.
Oh well! It's good to be the smart one aeh!
thanks a lot dude.
