How many statute miles are in one nautical mile?

One nautical mile is equivalent to approximately 1.15 statute miles. This conversion is based on the definition of a nautical mile, which is tied to the Earth's geometry. Specifically, one nautical mile is defined as one minute of latitude along any meridian, which correlates closely to the measurable distances on the globe.

In practical terms, this means that when navigating over water or in the air, distances measured in nautical miles are more directly related to the curvature of the Earth compared to statute miles, which are used on land. The relationship of 1 nautical mile to about 1.15 statute miles is important for pilots and mariners as it allows for consistent and accurate navigation across varied terrains and gives them the ability to transfer and interpret navigational charts effectively. Understanding this conversion is essential in aviation and maritime operations.
