Feet Per Minute to Miles Per Hour (ft/min to mph)
1 foot per minute equals 0.01136363636 miles per hour (rounded).
How to convert feet per minute to miles per hour
To convert feet per minute to miles per hour, multiply the number of feet per minute by 0.01136363636. The factor is rounded to 10 significant digits. To go the other way, multiply miles per hour by 88.
miles per hour = feet per minute × 0.01136363636
Example: 10 feet per minute = 0.1136363636 miles per hour.
About these units
Foot Per Minute (ft/min)
Exactly 0.00508 m/s. Used for climb rates in aviation.
Pilots in most ICAO member countries read their climb and descent in feet per minute, a convention kept even in otherwise metric countries. The vertical speed indicator in an aircraft such as the Robinson R22 helicopter shows ft/min, and the Wikipedia article on rate of climb quotes a Cessna 172 at maximum weight climbing at 721 ft/min, which is 3.66 m/s.
The arithmetic checks out: 721 multiplied by 0.00508 m/s per ft/min gives 3.663 m/s. The conversion factor is exact, because a foot is 0.3048 m and a minute is 60 s, so 1 ft/min is 0.3048 divided by 60, or 0.00508 m/s. Variometers are sometimes calibrated in knots instead, where 1 kn is about 0.514 m/s.
1 foot per minute = 0.00508 meters per second (exactly).

Mile Per Hour (mph)
Exactly 0.44704 m/s. The unit for road speeds in the US, UK and a few other countries.
Early British motoring law is the best window into this unit. The 1861 Locomotive Act set a limit of 10 mph for light locomotives. The 1865 Red Flag Act cut it to 4 mph in the country and 2 mph in towns, with a person walking ahead with a flag. The Locomotives on Highways Act of 1896 raised it to 14 mph, and the Motor Car Act of 1903 to 20 mph. In 1931 all limits for cars were abolished, and 30 mph in built-up areas returned in 1935.
The mile per hour combines the mile, set at 5,280 feet in Elizabeth I's reign, with the hour, and it equals exactly 0.44704 m/s or 1.609344 km/h. The United Kingdom and United States use it on roads, along with several smaller countries, mostly territories or former territories of those two, and the US, Canada and Ireland use it for rail. Sports such as cricket, tennis and baseball quote ball speeds in it. Aviation and shipping prefer knots, about 0.869 of one mph each.
1 mile per hour = 0.44704 meters per second (exactly).
