## How to Convert Feet Per Second to Knots

To convert a foot per second measurement to a knot measurement, multiply the speed by the conversion ratio. One foot per second is equal to 0.592484 knots, so use this simple formula to convert:

The speed in knots is equal to the feet per second multiplied by 0.592484.

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

Feet per second and knots 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.

## Knots

One knot is equal to a speed of one nautical mile per hour,^{[2]} 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.
