Units explained
Nautical Mile
A nautical mile is a unit of length equal to exactly 1,852 meters, defined as one minute of arc along any meridian of the Earth. It is the standard unit for sea and air navigation worldwide.
Originally defined as one minute of arc along a great circle of the Earth, making it convenient for celestial navigation. The International Hydrographic Organization (IHO) standardized the value at exactly 1,852 meters in 1929.
Nautical miles are used in maritime navigation, aviation, and international law (territorial waters, exclusive economic zones). Speed in nautical miles per hour is called a knot. The nautical mile is distinct from the statute (land) mile.
Defined for celestial navigation since antiquity; standardized to 1,852 m exactly by the IHO in 1929; adopted by the International Civil Aviation Organization (ICAO) for aviation use.
US Survey Foot
The US Survey Foot is a legacy unit of length defined as exactly 1200/3937 meters (approximately 0.3048006 m). It differs from the modern international foot by about 2 parts per million.
Established in the United States by the Mendenhall Order of 1893, which defined the foot in terms of the meter as 1200/3937 m. The US continued using this value for surveying even after the 1959 International Yard and Pound Agreement standardized the international foot at exactly 0.3048 m.
Used in US land surveying, geodetic measurements, state plane coordinate systems, and legal land descriptions. The US Survey Foot was officially deprecated by NIST and NOAA effective December 31, 2022, with the international foot becoming the sole US standard. Legacy data and recorded land surveys still reference it.
Mendenhall Order of 1893 defined the foot as 1200/3937 m; persisted in US surveying after 1959; officially deprecated by NIST/NOAA as of December 31, 2022.

Step-by-step: convert nautical miles to us survey feet
- Write down the value in nautical miles (nmi).
- Multiply that value by the factor 6076.1033333333.
- The product is the equivalent value in us survey feet (sft).
- To reverse, multiply the us survey foot value by 0.0001645792.
Worked examples
Example 1 — Convert 1 nmi to sft:
1 × 6076.1033333333 = 6076.1033333333 sft
Example 2 — Convert 100 nmi to sft:
100 × 6076.1033333333 = 607610.3333333333 sft
Real-world example — Geographic to human-scale conversion
One nautical mile converts to a precise number of us survey feet — the everyday arithmetic for navigation systems, race-distance calculations, and any context where bigger geographic units must be related to the smaller working units.
1 nmi × 6076.1033333333 = 6076.1033333333 sft
Real-world example — Lap pacing and route segmentation
Translating a nautical mile-scale distance into us survey feet is how runners, cyclists, and route planners convert top-line totals into the working segments they actually pace and execute.
1 nmi × 6076.1033333333 = 6076.1033333333 sft
Real-world example — Track athletics distances
A 1-nautical mile running track equals one thousand us survey feet. Track athletes' lap pacing converts the lap (often 400 of the smaller unit) into the fractional race distance whenever a coach reviews splits.
1 nmi × 6076.1033333333 = 6076.1033333333 sft
