Looking to change a quantity of feet per second to kilometres per hour? Use our accurate and simple ft/s to km/h speed converter for any maths calculations!

Used to measure the speeds of different types of moving objects, **feet per second** is used for objects that travel at slower speeds than those measured by **kilometres per hour**, such as cars. While km/h is found to be used internationally and is common to be used for road signs in many countries, ft/s is rather used in scientific industries. We have many speed converters to choose from, including this **feet per second to kilometres per hour converter**.

## How to use the Converter for Feet/s to Kilometres/h?

In the box above, enter the amount of feet per second you need to change and click “convert” for our speed calcualtor to give a new amount in kilometres per hour. The opposite conversion would be to convert kilometres per hour to feet per second.

## Formula to Convert ft/s – km/h

When doing this **ft/s to km/h conversion**, you might be interested to know the mathematical formula behind the equation so we have provided it for you below. To give some examples, 22 ft/s = 24.14 km/h and 45 ft/s = 49.38 km/h

**[number of] feet per second / 0.911344 = [number of] kilometres per hour**

## 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. Feet per second is often found to be used in chemistry and physics, where you may need to convert measurements into mph or km/h. It is used to calculate speeds of slower moving objects. Try out our **feet/second to kilometres/hour converter**.

## When to use km/h?

**Kilometres per hour** is the most common unit of speed that is used worldwide. Found on road signs and in car speedometers, it has several different abbreviations such as the official km/h, kph, kmph and km/hr. In American English, this unit of speed is spelt as kilometers per hour instead. Use our **ft/s – km/h speed converter** above.
