How does the UWO Power Rating compare to the Torque Rating on the DEWALT Cordless Drills?

We no longer use torque to rate the power of our drills but instead use Unit Watts Out or UWO.
UWO is the maximum power output for a drill system. This method takes into account the efficiency of the entire drill system (transmission, clutch, and chuck) giving you a measurement where it really matters on the job; at the chuck.
The drill’s Power Rating is measured by its Units Watts Out (UWO), the point where the drill’s speed and torque output are the highest.
The higher a drill’s Power Rating, or UWO, the faster it will perform on the jobsite.
