Damn cat. Won't leave those birds alone.

Pat,

My reading is that Bill Potts is visulazing short distances in meters and
sensing short time intervals in seconds, and the two together as he watches
an object, perhaps a feather, blowing freely in the wind.

The same can be done easily with respect to vehicles moving slowly in a
construction zone.  The same are not possible in kilometers and in hours for
small values of each.  Go SI, speed in m/s.

Gene.
