Hai I need yours one help I need now a solving formula for converting the ft/min to RPM & m/min to RPM can you help me..?.

Post the exact problem. There are factors, such as the radius of the wheel, to consider in converting from ft/min to rpm.

The circumference of a wheel is 2{\pi}r.

Therefore, if the wheel is measured in feet, there are 2{\pi}r feet in one revolution.

It depends on how long one revolution is... :rolleyes:

Lol, same time galactus! :p (btw, my last question in AMC thread is still unanswered... :()
