# Convert mph to feet per second

Please provide values below to convert mile/hour [mi/h] to foot/second [ft/s], or *vice versa*.

### Mile/hour

**Definition:** The unit miles per hour (symbol: mph) is a measurement of speed in the imperial and United States customary systems. It expresses the number of statute miles traveled over the period of one hour. One mph equals exactly 1.609344 kilometers per hour (km/h).

**Current use:** Along with km/h, mph is most typically used in relation to road traffic speeds. It is most widely used in the United States, the United Kingdom, and their related territories. It is also used in the Canadian rail system, though the Canadian road systems use km/h.

### Feet per second

**Definition:** A foot per second (symbol: ft/s) is a unit of speed and velocity that expresses the time taken in seconds to travel a specific distance in feet. It is equal to 0.3048 meters per second, the International System of Units (SI) derived unit of speed and velocity. It is also equal to 0.592484 knots and 0.681818 miles per hour.

**History/origin:** The foot per second is a measurement based in systems like the imperial and United States customary systems of units, where the foot is the preferred unit of length.

**Current use:** The foot per second is not widely used. The meter per second is the preferred measurement in scientific contexts, and either miles per hour or kilometers per hour are more common in everyday use for describing road speeds. The foot per second is also a relatively small unit of measurement making it difficult for use on a larger scale.

### How to Convert Mile/hour to Foot/second

1 mi/h = 1.4666666667 ft/s

1 ft/s = 0.6818181818 mi/h

**Example:** convert 15 mi/h to ft/s:

15 mi/h = 15 × 1.4666666667 ft/s = 22 ft/s
