Convert nautical miles into both kilometers and statute (land) miles.
How it works
The international nautical mile is defined as exactly 1,852 meters, giving 1 nmi = 1.852 km and, since a statute mile is 1,609.344 meters, 1 nmi = 1.150779 statute miles.
What this does not include
This converts a nautical-mile distance to two other units — it doesn’t convert speed (knots), which this site’s separate knots-to-kph calculator handles.

Why is the nautical mile different from the statute mile?
The nautical mile was originally defined to relate to one minute of latitude on Earth’s surface, a navigational convenience that has nothing to do with the statute mile’s separate historical origin.
Where is the nautical mile still used today?
Maritime and aviation navigation continue to use the nautical mile (and its associated speed unit, the knot) as the standard, even in countries that otherwise use metric or statute-mile units for everyday distances.
Is a nautical mile longer or shorter than a statute mile?
Longer — 1 nautical mile is about 1.15 statute miles, so a given nautical-mile distance always converts to a larger number of statute miles.
