What is a Nautical Mile and a Light Year?
A nautical mile is a unit of length used in marine and air navigation. It is defined as exactly 1,852 meters.
A light-year is a unit of astronomical distance equal to the distance that light travels in one Julian year in a vacuum (approximately 9.461 trillion kilometers or 5.879 trillion miles).
Note: The Nautical Mile is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Light Year belongs to the imperial/US customary system.
History of the Nautical Mile and Light Year
The nautical mile originated from the length of one minute of arc of latitude along any meridian. It was standardized internationally in 1929.
The concept was first used by Friedrich Bessel in 1838 when measuring the distance to the star 61 Cygni.

Frequently Asked Questions
Questions About Nautical Mile (NM)
Why is a nautical mile different from a statute mile?
A statute mile (used on land, 1609.344 meters) is based on historical measurements. A nautical mile (1852 meters) is derived from the Earth's circumference (1 minute of latitude) and simplifies navigation calculations.
How many feet are in a nautical mile?
One nautical mile is approximately 6076.115 feet.
What is a knot in relation to a nautical mile?
A knot is a unit of speed equal to one nautical mile per hour. It's commonly used in maritime and aviation contexts.
About Light Year (ly)
Is a light-year a unit of time or distance?
A light-year (ly) is a unit of distance, not time. It represents the distance light travels in one year.
How far is a light-year in kilometers and miles?
One light-year is approximately 9.461 trillion kilometers (9.461 x 10^12 km) or 5.879 trillion miles (5.879 x 10^12 mi).
What is the closest star to Earth in light-years?
Excluding the Sun, the closest star system to Earth is Alpha Centauri, which is about 4.37 light-years away.
