Convert feet to nautical miles for maritime navigation, aviation altitude, and offshore operations. Accurate calculator with 1 foot = 0.000164579 nautical miles.
1 foot equals 0.00016457888833347557 nautical mile
Formula: nmi = ft × 0.000164579
Converting to foot from feet to nautical miles is essential for maritime professionals, pilots, and offshore engineers. With 1 nautical mile equaling exactly 6,076 feet, precision in this conversion directly impacts navigation safety, flight planning accuracy, and regulatory compliance across international waters and airspace.
Nautical mile conversions are critical for safety at sea and in the air. A navigation error of just 100 feet across a 50 nautical mile voyage compounds into dangerous positioning mistakes. International maritime law requires depth soundings, visibility reports, and distance calculations in feet or meters converted to nautical miles for standardized communication between vessels and coastal authorities.
Commercial vessels navigate using nautical miles as the standard distance unit, with depth measurements in feet. Ship captains must convert sonar readings, radar distances, and chart measurements from feet to nautical miles for course plotting and collision avoidance calculations. International Maritime Organization (IMO) regulations require all distance reporting in nautical miles.
Pilots and air traffic controllers work with altitude in feet but measure horizontal distances in nautical miles. Flight plans, approach procedures, and separation standards require constant conversion between feet (vertical measurement) and nautical miles (horizontal distance). Federal Aviation Administration (FAA) and International Civil Aviation Organization (ICAO) mandate this dual-unit system for safety.
| feet | nautical miles |
|---|---|
| 10 ft | 0.001646 nmi |
| 50 ft | 0.008229 nmi |
| 100 ft | 0.016458 nmi |
| 500 ft | 0.082289 nmi |
| 1000 ft | 0.164579 nmi |
Formula: nmi = ft × conversion factor

Exactly 6,076 feet equals one nautical mile (or 1,852 meters). This precise definition, established internationally in 1929, means 1 foot = 0.000164579 nautical miles. For practical navigation, remember that 1 nautical mile ≈ 6,076 feet, making it approximately 15% longer than a statute mile (5,280 feet). This difference is crucial for maritime charts and flight planning—a 100 nautical mile distance would be only 86.9 statute miles, creating significant navigation errors if confused.
Nautical miles are mathematically linked to Earth's geography: one nautical mile equals one minute of latitude, allowing navigators to measure distances directly from latitude coordinates on charts without calculation. This relationship is so fundamental that it predates GPS by centuries and remains the international standard under maritime and aviation law. Additionally, nautical miles relate directly to knots (nautical miles per hour), making speed and distance calculations intuitive for mariners and pilots worldwide.
