To calculate the speed in surface feet per minute, multiply the speed in meters per minute by the conversion factor 3.28084. This will give you the equivalent speed in surface feet per minute.

RDG Tools was started up by Richard Dickinson in 1992. We started exhibiting at model engineering exhibitions in 1994 and realised from the shows that people wanted quite specialised tooling for their machines and also a wide range of tooling which they could adapt to suit their needs.

The following steps outline how to calculate the Speed in Surface Feet per Minute (SFM) using the Meters per Minute (M/Min) value.

The following formula is used to calculate the conversion from meters per minute (M/Min) to surface feet per minute (SFM).

M/Min to SFM is a conversion from meters per minute to surface feet per minute. These are both units of speed used in machining to denote the speed at which a cutting tool is moving across the surface of the material being cut. The conversion is often necessary because different machines and tools may use different units of measurement.
