## How to use the Converter from Km/h to Knots?

Enter into our **converter km/h – kn **above the number of kilometres per hour you wish to convert and click “convert” for our unit calculator to present the equivalent in knots. To do the opposite conversion, convert knots to kilometres per hour.

## Formula to Convert km/h – kn

When doing this **kilometres per hour to knots conversion** by hand, it might be useful to understand the mathematical equation used to calculate the difference between these two units of speed. As some examples, 12 km/h = 6.48 kn and 60 km/h = 32.4 kn

**[number of] kilometres per hour / 1.852 = [number of] knots **

## 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 km/h, the official one, kph, kmph and km/hr. In American English, this unit of speed is spelt as kilometers per hour instead. Use our **km/h to kn speed converter** above.

## 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. Its main purpose is to calculate the speed of vessels relative to the fluids in which they travel, whether that is water or air. A knot is equivalent to one nautical mile exactly.
