Exactly right--but unit conversion need not be seen as difficult. Use the 'units' program on linux or even do as I am doing now on my droid: I typed 400W / 540 ozf in And asked for output in RPM which gave me 1000 rpm. Units figures out all conversions so you can throw at it any mix and it will figure them out
Note that I had to use ozf because oz is a unit of mass not force On Aug 11, 2011 7:11 AM, "Peter Blodow" <p.blo...@dreki.de> wrote: > Hello Mark and Andy, > > > Power (in watts) equals the torque (in Newton times meter) times the rpm > (in turns per sec) of the motor shaft times Pi.
