# Knots to Feet Per Second Conversion

Enter the speed in knots below to get the value converted to feet per second.

Results in Feet Per Second: 1 kn = 1.68781 ft/s

## 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. One knot is equal to 1.68781 feet per second, so use this simple formula to convert:

feet per second = knots × 1.68781

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.
5 kn = (5 × 1.68781) = 8.439049 ft/s

## Knots

One knot is equal to a speed of one nautical mile per hour, 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.

## Feet Per Second

Feet per second are a measurement of speed expressing the distance travelled 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.

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.
