Quick answer
Divide metres per minute by 0.3048 to get surface feet per minute. A cutting speed of 60 m/min is about 196.85 SFM. Use this conversion when a machining reference gives the cutting speed in a different unit.
Formula and assumptions
One foot is exactly 0.3048 metres. Divide m/min by 0.3048 to get SFM.
Worked example
100 m/min is approximately 328.08 SFM.
