Want to change a quantity of knots into feet per second? Use our knots to ft/s speed converter to help with any conversion. More converters available here.

**Feet per second** and **knots **may not be as familiar as mph or km/h because we do not use them or see them being used on a regular basis. They** **are both used in specific industries, whether that be science or maritime, as they are suitable for the speed of certain objects. Use our **knots to feet per second converter** above, or try out the other speed converters we have.

## How to use the Converter for Knots to Feet per second?

Simple enter in the box above a quantity of knots and click “convert” to begin the **kn – ft/s conversion** and see the new quantity in feet per second appear. To convert the other way, **convert feet per second to knots**.

## Formula to Convert kn – ft/s

Our **knots – feet per second conversion tool** uses an accurate formula to convert one unit of speed to another, and for these two units the speed equation is shown below. For example, 27 kn = 45.57 ft/s and 60 kn = 101.3 ft/s

**[number of] knots x 1.68781 = [number of] feet per second**

## When to use knots?

The unit of speed known as **knots** is an important measurement used in meteorology but also in the air navigation and maritime industries. A knot is equivalent to one nautical mile exactly. Its main purpose is to calculate the speed of vessels relative to the fluids in which they travel, whether that is water or air. Above is our** knots – ft/s calculator**.

## When to use ft/s?

Although it is not considered as a common or mainstream measurement, **feet per** **second**, is another unit used to calculate speed. It is used to calculate speeds of slower moving objects. Feet per second is often found to be used when you need to convert measurements into mph or km/h, such as in chemistry and physics. Try out our **knots to feet/s converter**.
