To convert a measurement in miles per hour to a measurement in feet per second, multiply the speed by the following conversion ratio: 1.466667 feet per second/mile per hour.

Since one mile per hour is equal to 1.466667 feet per second, you can use this simple formula to convert:

feet per second = miles per hour × 1.466667

The speed in feet per second is equal to the speed in 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.
feet per second = (5 mph × 1.466667) = 7.333333 ft/s

Miles per hour and feet per second are both units used to measure speed. Calculate speed in miles per hour or feet per second using our speed calculator or keep reading to learn more about each unit of measure.

What Are 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:
vmph = dmithr

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

What Are 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 the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.[2] For example, ft/s is expressing a change in length or distance relative to a change in time.

Feet per second can be expressed using the formula:
vft/s = dfttsec

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