In order to assign a displacement value to a revolution you have to have a diameter of the item rotating, since a centerline spining at a given RPM does not necesarily mean displacement, I will assign a 1 meter diameter wheel which perimeter known as circumference will be assigned the displacement value
3.1416 meters per revolution, under this notion you can perform any linear or time conversion you might want do, your conversions would look someting like this.

RPS=Revolutions Per Second
MPS=rps*circumference
Circumference=P*D
rps=rpm/60
For 6800 RPM with a 1 meter Diameter wheel we have
Circumference=3.1416*1=3.1416
rps=6800/60=113.3333
mps=113.3333*3.1416=356.0479
MPS=356.0479

for 1000 mps with the same 1 meter Diameter wheel we have:
RPS=MPS/Circumference=1000/3.1416=318.3091
RPM=RPS*60=318.3091*60=19,098.95
RPM=19,098.95
