First you need to know how many feet are in a mile.
I looked up that a foot is 1/3 of a yard and a mile is 1760 yards, so there are 3*1760=5280 feet in a mile (God, I hate these units)

Then you can just write:
1 [mile/hour] = 1 [5280 ft/3600 seconds]=5280/3600 ft/s=22/15 ft/s.

EDIT: There are 3600s in an hour. duh.
 when i convert 65 mph into ft/s is it 95.33 ft/s and and when converting 65mph into km/h is it 104.60736 km/h?
