Convert 85 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 explore the definitions of kilometers and nautical miles, as well as provide a clear method to convert 85 km into nautical miles.

km Definition

Kilometer (km) is a unit of length in the metric system, equivalent to 1,000 meters. It is commonly used to measure distances on land, such as the distance between cities or the length of roads. The kilometer is widely adopted in most countries for everyday use and scientific purposes.

nm Definition

Nautical mile (nm) is a unit of measurement used in maritime and air navigation, equivalent to one minute of latitude. One nautical mile is approximately 1.852 kilometers. Nautical miles are essential for navigation because they allow for more accurate distance calculations based on the curvature of the Earth.

How to Convert 85 km to nm

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

Nautical Miles (nm) = Kilometers (km) / 1.852

For example, to convert 85 km to nautical miles:

85 km ÷ 1.852 ≈ 45.93 nm

Therefore, 85 kilometers is approximately 45.93 nautical miles.

FAQs

What is the relationship between kilometers and nautical miles?
