Units explained
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.
Pole
A pole is an Imperial unit of length identical to the rod and perch — 16.5 feet (about 5.03 m). The names are regional and historical variants for the same measurement.
The pole derives from medieval English land-surveying. The name comes from the physical wooden pole used by surveyors to lay out the unit on the ground.
Poles appear in historical land records, particularly older US public-land surveys. Functionally identical to rod and perch in all calculations.
Medieval English surveying origin; identical to the rod since 1620; became exact via the 1959 International Yard and Pound Agreement.

Worked examples
Example 1 — Convert 1 sft to pole:
1 × 0.0606061818 = 0.0606061818 pole
Example 2 — Convert 100 sft to pole:
100 × 0.0606061818 = 6.0606181818 pole
Real-world example — Maritime depth conversion
A 10-us survey foot sounding depth converts cleanly into poles. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 sft × 0.0606061818 = 0.6060618182 pole
Real-world example — Reference scenario in case of fallback
Conversion between human-scale length units is the everyday workflow of architecture, athletics, and apparel design — three of the most common contexts that span metric and imperial systems.
1 sft × 0.0606061818 = 0.0606061818 pole
Real-world example — Adult height conversion
A 1.8-us survey foot-tall person measures a value in poles that converts the height to the unit favoured by American forms, schools, or driver's licences. This is daily routine for anyone living between metric and imperial systems.
1.8 sft × 0.0606061818 = 0.1090911273 pole
