RPM to SFM Calculator
Posted by Dinesh onOnline speeds / feeds conversions calculator helps to calculate Revolutions Per Minute (RPM) to Surface Feet per Minute (SFM) units.
RPM to SFM Calculation
Formula:
SFM = RPM × D × (π ÷ 12)
where,D = Workpiece diameter
SFM = Surface Feet per Minute
RPM = Revolutions Per Minute
