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
but apparently I should get 283rad/s. Which is half of what I get.

help!

2. Hello, lemonz!

I am trying to convert revolutions to radians.

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

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

You are right!
