## How to Convert Knots to Feet per Second

To convert a measurement in knots to a measurement in feet per second, multiply the speed by the following conversion ratio: 1.68781 feet per second/knot.

Since one knot is equal to 1.68781 feet per second, you can use this simple formula to convert:

The speed in feet per second is equal to the speed in knots multiplied by 1.68781.

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

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

## What is a Knot?

One knot is equal to a speed of one nautical mile per hour,^{[1]} or one minute of latitude per hour.

Knots can be abbreviated as *kn*, and are also sometimes abbreviated as *kt*. For example, 1 knot can be written as 1 kn or 1 kt.

## 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:

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.
