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

To convert a foot per second measurement to a mile per hour measurement, multiply the speed by the conversion ratio.

Since one foot per second is equal to 0.681818 miles per hour, you can use this simple formula to convert:

The speed in miles per hour is equal to the feet per second multiplied by 0.681818.

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

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

## 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.^{[1]}

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.

## Miles Per Hour

Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour.^{[2]}

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.
