Convert 155 km to nm

Converting kilometers (km) to nautical miles (nm) is essential for navigation, especially in maritime and aviation contexts. In this post, we will clearly define both units and provide a simple method for converting 155 km to nautical miles.

km Definition

Kilometer (km) is a metric unit of length equal to 1,000 meters. It is commonly used in most countries around the world for measuring distances on land, such as the distance between cities or the length of a road.

nm Definition

Nautical mile (nm) is a unit of measurement used in maritime and air navigation. It is based on the circumference of the Earth and is equal to one minute of latitude, approximately 1.852 kilometers. Nautical miles are used to measure distances over water and in aviation to ensure accurate navigation.

How to Convert 155 km to nm

To convert kilometers to nautical miles, you can use the following formula:

nm = km ÷ 1.852

Using this formula, to convert 155 km to nautical miles:

nm = 155 km ÷ 1.852 ≈ 83.66 nm

Therefore, 155 kilometers is approximately 83.66 nautical miles.

FAQs

What is the difference between km and nm?

The primary difference is that kilometers are used for land distances, while nautical miles are specifically used in maritime and aviation contexts.

Why do we use nautical miles in navigation?

Nautical miles are used because they are based on the Earth is geometry, making it easier to navigate by latitude and longitude.

Can I convert nm back to km?

Yes, to convert nautical miles back to kilometers, you can use the formula: km = nm x 1.852.
