# Units in Angular Velocity

**1. The problem statement, all variables and given/known data**

Hello, I am doing a mechanisms homework assignment in which a hydraulic piston moves out and moves a link connected to the piston in an angular fashion. I’m just a bit confused about the units of angular velocity and I feel very foolish asking this.

**2. Relevant equations**

[tex]\omega \times r = v[/tex]

[tex]\omega = \frac{v}{r}[/tex]

**3. The attempt at a solution**

[tex] v=0.751751\frac{m}{s} [/tex]

[tex] r=0.6 m [/tex]

[tex] \omega=\frac{v}{r}=\frac{0.751751 \frac{m}{s}}{0.6 m} = 1.25 \frac{rad}{s} [/tex]

Can someone just double check that the units are indeed radians per second? SI units for angular velocity is rad/s.. and this is SI. Just want to double check that it’s not rev per second. I know, it’s foolish. Thanks in advance!
