Good to Know About Nautical Miles to Light-years Conversion
The nautical mile was humanity's first precision distance unit for travel: 1 arcminute of latitude = 1 NM. The light-year is humanity's most dramatic distance unit: the distance light travels in a year. Between them lies the entire history of human ambition to measure farther and farther from shore.
Nautical Miles to Light-years: What You Need to Know
The nearest star is about 21.66 trillion NM away (4.24 light-years). Light travels about 161,875 NM per second. A circumnavigation (21,600 NM) is about 4.23 x 10-9 light-years - a billionth of a stellar gap.
What is a Nautical Mile? nmi
Exactly 1852 meters by international agreement. Based on one minute of arc of latitude at the Earth's surface. The standard unit for maritime and air navigation.

Nautical Miles to Light-years FAQ
-
One nautical mile equals approximately 1.958 x 10-13 light-years.
-
One light-year contains approximately 5.108 x 1012 NM (about 5.1 trillion).
-
About 582,750,000 knots (NM/hour). That is about 583 million knots.
Non-Frequently Asked Questions About Nautical Miles to Light-years
Questions nobody should ask - but someone did.
-
Earth's circumference is 21,600 NM. 1 light-year is 5.108 trillion NM. That is about 236 million laps. If Magellan's crew circumnavigated once every 3 years, they would need 709 million years. The crew would not enjoy this assignment.
-
Humanity has probably sailed about 100 trillion NM total in maritime history. 1 light-year is 5.1 trillion NM. So all sailing in human history equals about 19.6 light-years - enough to reach several nearby stars including Procyon. Collectively, humanity has sailed to the stars. Just not in the same direction.
-
About 583 million knots. The fastest ship ever (USS Enterprise at trials) made about 35 knots. Light is 16.6 million times faster. If the Enterprise accelerated by 1 knot per year, it would reach light-speed in 583 million years. Warp drive is not optional.
