## How to Convert Miles Per Hour to Feet Per Second

To convert a mile per hour measurement to a foot per second measurement, multiply the speed by the conversion ratio. One mile per hour is equal to 1.466667 feet per second, so use this simple formula to convert:

The speed in feet per second is equal to the miles per hour multiplied by 1.466667.

**For example,**here's how to convert 5 miles per hour to feet per second using the formula above.

Miles per hour and feet per second are both units used to measure speed. Keep reading to learn more about each unit of measure.

## Miles Per Hour

Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour.^{[1]}

The mile per hour is a US customary and imperial unit of speed. Miles per hour can be abbreviated as *mph*, and are also sometimes abbreviated as *mi/h* or *MPH*. For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH.

Miles per hour can be expressed using the formula:

v_{mph} = d_{mi}t_{hr}

The velocity in miles per hour is equal to the distance in miles divided by time in hours.

## Feet Per Second

Feet per second are a measurement of speed expressing the distance traveled in feet in one second.

The foot per second is a US customary and imperial unit of speed. Feet per second can be abbreviated as *ft/s*, and are also sometimes abbreviated as *ft/sec* or *fps*. For example, 1 foot per second can be written as 1 ft/s, 1 ft/sec, or 1 fps.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^{[2]}

Feet per second can be expressed using the formula:

v_{ft/s} = d_{ft}t_{sec}

The velocity in feet per second is equal to the distance in feet divided by time in seconds.
