About Converting mph to Foot per Hours
mph and Foot per Hours both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). mph is most often used for road speed limits and vehicle speedometers in the us and uk.
Formula
foot per hours = mph × 5280
This factor comes from each unit's defined relationship to the category's base unit: 1 mph equals 0.44704 base units, and 1 foot per hours equals 0.0000846666666667 base units, so dividing one by the other gives the direct mph-to-foot per hours factor of 5280.
Simple example
1 mph × 5280 = 5,280 ft/h
1 mph = 5,280 foot per hours.
Real-world example
10 mph × 5280 = 52,800 ft/h
10 mph = 52,800 foot per hours.

History of the mph
Miles per hour is a compound unit with no separate origin story of its own — it follows automatically once the statute mile was fixed at 5,280 feet in 1593 and later refined to exactly 1,609.344 meters by the 1959 international agreement that also standardized the pound.
Historical origin. mph was not the invention of a single named person; it developed through the process described above.
