Nautical miles (nm) are a unit of measurement used primarily in maritime and air navigation. One nautical mile is equivalent to one minute of latitude and is approximately equal to 1.15078 miles or 1,852 meters. Nautical miles are essential for navigation over bodies of water, where the curvature of the Earth is a factor.

How to Convert 981 km to nm

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

[ text{Nautical Miles} = text{Kilometers} times 0.539957 ]

Using this formula, we can calculate the conversion for 981 km:

[ text{Nautical Miles} = 981 times 0.539957 approx 529.046 ]

Therefore, 981 kilometers is approximately 529.05 nautical miles.

FAQs

1. What is the difference between kilometers and nautical miles?

Kilometers are used primarily on land, while nautical miles are used in maritime and aviation contexts, taking into account the Earth is curvature for navigation.

2. Why do navigators use nautical miles instead of kilometers?
