Rad/s vs rev/min- label question

  • #1

Main Question or Discussion Point

According to the equations for angular, linear velocity and acceleration, it is in rad/s. So, for my own mindset, I always change everything to rad/s. (As opposed to rev/min or something) And now it's a habit, like reducing fractions. I didn't understand what we were doing very well for some reason, so that may be part of it. We don't do much work in my physics class, so it's easy to get lost. :P
Is this bad to do? Or at least annoying in the real science world? Because if it is unnecessary or annoying, then I shall stop. What do physicists/engineers/whatever use? My teacher said he wasn't sure, but the answer book took both answers.

Using everything in common units is fine in almost all walks of life, especially textbook cases.

In engineering you get all sorts of very odd numbering conventions. You will find one company always uses RPM and others use rad/s. I've even seen Rev/s, and CPS used.

Almost without exception, physicists use radians/second. You probably can't go wrong in physics using this convention.
