Convert nautical miles to statute miles for maritime navigation, aviation, and shipping. Accurate calculator with 1 nautical mile = 1.15078 miles conversion factor and real-world examples.
1 nautical mile equals 1.150778673116563 mile
Formula: mi = nmi × 1.15078
The nautical mile and statute mile serve different purposes across transportation industries. One nautical mile equals approximately 1.15078 statute miles, a distinction critical for maritime professionals, pilots, and navigators. Understanding this conversion prevents navigation errors that could cost lives or thousands of dollars in fuel inefficiency.
Maritime navigation, aviation, and shipping rely on precise distance measurements. A single nautical mile miscalculation across a 1,000 nautical mile voyage creates a 150.78-mile error in statute miles. For commercial shipping, this translates to incorrect fuel consumption estimates, missed delivery windows, and regulatory compliance issues. Aviation crews must maintain absolute accuracy for flight planning and safety protocols.
Ships navigate using nautical miles and knots as international maritime standards established by the International Maritime Organization. Port authorities, cargo vessels, and fishing fleets must convert nautical distances to statute miles for inland waterway navigation, fuel calculations, and regulatory reporting to US authorities. Accurate conversion ensures correct voyage planning and cost estimation.
Aircraft operate using nautical miles as the international standard for airspeed, distance, and navigation. Pilots file flight plans in nautical miles, but must convert to statute miles for US domestic operations, runway distances, and visibility reports. Federal Aviation Administration (FAA) requires pilots to understand both systems for safety and regulatory compliance.

This nautical mile to mile converter uses high-precision conversion factors to ensure accurate results for professional and academic use.
Our calculator provides results with up to 10 decimal places for maximum accuracy.
One nautical mile equals exactly 1.15077945 statute miles (often rounded to 1.15078). This conversion exists because nautical miles measure one minute of arc along Earth's meridian (1,852 meters), while statute miles measure 5,280 feet (1,609.344 meters). For quick mental calculations, multiply nautical miles by 1.15; for precise navigation, fuel planning, and regulatory documents, use 1.15078. For example, a 100 nautical mile journey equals 115.078 statute miles.
Nautical miles are based on Earth's circumference and latitude measurements, making them ideal for navigation using latitude and longitude coordinates. One degree of latitude equals 60 nautical miles precisely, allowing navigators to calculate distances directly from charts and GPS coordinates. The International Maritime Organization and International Civil Aviation Organization adopted nautical miles as the global standard for ocean and air navigation. Statute miles, based on historical English measurements, remain standard only in the United States and some Commonwealth nations for land-based travel.
