Land travel and air travel both measure distances in miles. For transportation by land, distance is calculated as land miles, or statute miles; for transportation by air, distance is calculated by nautical miles. One nautical mile equals roughly 1.51 land miles.

Skill level:


  1. 1

    Calculate the land miles you will be travelling. Example, the distance from Key West to Boston is about 1,372 land miles.

  2. 2

    Apply the conversion equation, land miles x .87 = nautical miles.

  3. 3

    Calculate 1372 land miles x .87. This equals 1193.6 nautical miles.

Tips and warnings

  • To convert nautical miles to statute miles, the rough equation is nautical miles x 1.15 = statute miles. For precise conversion, visit the website listed in the resource section.
