Conversion Definitions

The following is a list of definitions relating to conversions between nanometers and nautical miles.

What is a nanometer (nm)?

A nanometer is a unit of Length or Distance in the Metric System. The symbol for nanometer is nm. There are 1,852,000,000,000 nanometers in a nautical mile. The International spelling for this unit is nanometre.

What is a nautical mile (M, NM, or nmi)?

A nautical mile is a non-SI unit of Length or Distance. A nautical mile is based on the circumference of the Earth and is used by sea and air navigators. It is approximately one minute of arc measured along any meridian. The symbol for nautical mile is M or NM or nmi. There are 0.0000000000005 nautical miles in a nanometer.

Conversion Formula

Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.

The formula to convert from nm to nautical miles is:

nautical miles = nm ÷ 1,852,000,000,000

Conversion Example

Next, let's look at an example showing the work and calculations that are involved in converting from nanometers to nautical miles (nm to nmi).
