Kilometer and nautical miles are two of the most heard units of measurement. They both are used to measure length but in different fields. But what if we ask you to convert kilometers to nautical miles? Yes, we know it would put you in a state of puzzlement, but we are here to help you.
This blog has been curated with precision to describe the meaning, process of km to nautical mile conversion, the km to nautical miles formula, and other aspects. It will help you to comprehend the concept better which will ease out the conversion process for you.
What is a kilometer?
A kilometer (km) is a unit used to measure the length and used in the mainstream and most common metric system. The value of a kilometer is equal to one thousand meters which is based on the fact that a kilo is a Si-based prefix for 1000. This unit of measurement is also used to express the distance between two different geographical points or locations on land across the globe. But this unit has an exception in use since the United States and the United Kingdom use statute mile as their measuring unit.
Current Use of Kilomete
Kilometer is used to measure the distance between two different geographical points or locations on land across the globe except for the United Kingdom and the United States.
What is a Nautical Mile?
A unit of measurement, nautical miles are used throughout the world in the arenas of marine, air-based navigation, and space. Nautical miles are also used to define the territorial waters alongside boundaries. Nautical miles were identified as 1/60 or a minute, historically, of the degree of latitude along with any longitudinal line. In today’s time, the nautical mile in the global scenario has been defined as being equal to 6076 ft and 1852 meters. A nautical mile is also equivalent to 1.151 miles. The word mile is derived from the word “mille passus”
‘ Which is a Latin word that is equal to a nautical mile per hour. Before this, navigation at sea was covered by the human eye until the year 1500 after which many navigational instruments were appointed for this purpose.
Current Use of Nautical Miles
The main use of nautical miles is in shipping, marine industries, and aviation. It is also used for several other purposes other than navigation.
Relation Between Kilometer and Nautical Miles
It is very easy to understand the km nautical mile relationship. While on the other hand, it is also of utmost importance to understand their relation for the km to nautical mile conversion. The relation between them is that km in nautical miles is equal to 0.5399568035 nautical miles (international). A nautical mile is equal to 1.852 kilometers according to the international system of calculation.
How to Convert Kilometers to Nautical Miles
The above-stated relation will help you to convert kilometers to nautical miles. As you would have learned by now, 1 kilometer = 0.5399568035 nautical miles. So, for the purpose of conversion, you need to multiply the value of kilometers by 0.5399568035. The result will be in nautical miles.
Km to Nautical Miles Formula
The km to nautical miles formula is: Nautical Miles = Kilometers x 0.5399568035.
Km to Nautical Miles Example
Let us understand the above-given relation and conversion process with the help of an example.
Example: 8 kilometers to nautical miles
Solution: So, by inserting the value of kilometers in the above formula we will get,
Nautical Miles = 8 x 0.5399568035 = 4.31965 nautical miles.
Hence, the value of 8 kilometers is equal to 4.31965 nautical miles.
