Multiply the number of Nautical Miles by 6.0013×10-14 to get Parsecs. Formula: pc = nmi × 6.0013×10-14. Example: 10 nmi × 6.0013×10-14 = 6.0013×10-13 pc. To reverse, divide Parsecs by 6.0013×10-14 to get Nautical Miles.

To convert Nautical Mile to Parsec, multiply by 6.0013×10-14. Example: 10 nmi = 6.0013×10-13 pc
To convert Parsec back to Nautical Mile, divide by 6.0013×10-14 (multiply by 1.6663×1013). Use the swap button above.
Start with 100 Nautical Miles = 6.0013×10-12 pc as your reference point. Scale up or down from there.
Celestial navigation instructors use nmi-to-parsec as the most dramatic scale contrast available — from the unit of ocean navigation to the unit of stellar distance — spanning 17 orders of magnitude in a single conversion.
1 parsec = 1.666×10¹³ nautical miles — 16.7 trillion nautical miles. Science communicators use this for maritime audiences: "One parsec is 16.7 trillion nautical miles — enough sea miles to circumnavigate the Earth 666 billion times."
The nautical mile was used by Magellan during the first circumnavigation (1519–22). The parsec was defined in 1913. These two units span 400 years of human exploration — from charting Earth's oceans to measuring stellar distances.
Physics courses at naval academies use nmi-to-parsec conversion in dimensional analysis exercises — connecting the operational measurement system of naval officers with the astronomical units of stellar physics.
Aquariums and maritime museums use nmi-to-parsec comparisons in exhibits to connect their ocean-focused audiences with stellar astronomy — showing how measurement scales from the navigator's chart to the astronomer's telescope.
Complete unit converters include nmi-to-parsec for completeness — serving researchers and educators who encounter both nautical miles in maritime science and parsecs in astrophysics within the same interdisciplinary publication.
The Nautical Mile is a unit of Length measurement (symbol: nmi). 1 nmi = 6.0013×10-14 pc. Used in scientific and practical Length measurement applications.
The Parsec is a unit of Length measurement (symbol: pc). It is part of an internationally recognised measurement system used alongside the Nautical Mile.
The nautical mile was defined by Earth's own geometry — one minute of arc of latitude along a meridian, approximately 1,852 metres. This elegant definition made it perfect for navigation: on any nautical chart, one nautical mile equals exactly one arcminute, allowing direct distance measurement with dividers without any conversion. The unit was used informally by mariners for centuries before the International Hydrographic Conference standardised it at exactly 1,852 metres in 1929. Today it is universally used in maritime and international aviation — the only two domains that never adopted kilometres for operational distances, largely because the geometric relationship to Earth's circumference remains too useful to abandon.
The parsec was introduced in 1913 by British astronomer Herbert Hall Turner. It equals the distance at which 1 astronomical unit subtends 1 arcsecond — approximately 3.086×10¹³ kilometres or 3.26 light-years. The name blends 'parallax' and 'arcsecond'. Professional astronomers prefer parsecs because parallax directly yields distance without intermediate calculation.
Common use: Nautical Mile to Parsec conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
