## How to Convert Knots to Feet per Second

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

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 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. 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 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.
