How many statute miles is equivalent to 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 derived from the Earth's circumference and is defined as one minute of latitude. Since a degree of latitude is approximately 60 nautical miles, understanding this helps connect the concept of distance on the surface of the Earth with navigational standards.

The approximation allows for easy conversions between nautical miles, which is commonly used in maritime and air navigation, and statute miles, which are typically used in the United States for road distances and other measures. This is why 1.15 statute miles is the correct conversion factor for nautical miles.
