## Nautical Mile Formula

The following equation can be used to convert miles to nautical miles.

1 NM = 1.15078 M

- Where NM is nautical mile
- M is typical mile

1 NM = 1.852 KM

- Where NM is nautical mile
- KM is kilometres

To calculate nautical miles from normal miles, multiply the miles by 1.15078.

## Nautical Mile Definition

A nautical mile is a measurement of distance that is equal to “one minute” of latitude. This distance is based on the circumference of the earth and is equal to 1.15078 miles.

A nautical mile can also be described as the distance traveled over 1 minute with a speed of one knot.

Both knot and nautical mile are most often used on ships as they travel the open seas. Since ships travel great distances, taking the circumference of the Earth into effect with their measurements helps standardize distance and speed.
