Good to Know About Astronomical Units to Nautical Miles Conversion
Maritime navigation uses nautical miles because they relate to Earth's geometry (1 NM = 1 arcminute of latitude). Space navigation uses AU because they relate to the Sun's gravity. Both are geometry-based units, just at incompatible scales.
Astronomical Units to Nautical Miles: What You Need to Know
The Earth-Sun distance is about 80.8 million nautical miles. A 12-nautical-mile territorial waters boundary is only 1.5 x 10-7 AU. A transatlantic crossing of 3,000 nautical miles covers 0.0000372 AU. These comparisons show the enormous gap between sea navigation and space navigation.

Astronomical Units to Nautical Miles FAQ
-
One AU contains approximately 80,776,388 nautical miles (about 80.8 million NM). Since 1 AU = 149,597,870,700 m and 1 NM = 1,852 m, divide accordingly.
-
One nautical mile is approximately 1.238 x 10-8 AU, or about 12.4 billionths of an AU.
-
No. Spacecraft navigation uses kilometers, AU, or radar-measured distances. Nautical miles are for maritime and aviation use only, based on the relationship to Earth's latitude (1 NM = 1 arcminute of latitude).
Non-Frequently Asked Questions About Astronomical Units to Nautical Miles
Questions nobody should ask - but someone did.
-
1 AU is about 80.78 million nautical miles. At 20 knots (typical cargo ship speed), it would take about 461,000 years. Your cargo would not arrive fresh.
