Units explained
Mile
A mile (statute mile) is an Imperial and US customary unit of length equal to 5,280 feet or exactly 1,609.344 meters. It is the standard unit for road distances in the United States and the United Kingdom.
The mile derives from the Roman mille passus ("thousand paces" — about 1,480 meters). The English statute mile was fixed at 5,280 feet by the Weights and Measures Act of 1593, and exactly defined as 1,609.344 m by the 1959 International Yard and Pound Agreement.
Miles are used in the US and UK for road signs, speed limits (mph), athletic events (one-mile run), and geographic distances. Aviation also uses statute miles for some visibility measurements.
Roman origin (mille passus); English statute mile fixed at 5,280 feet in 1593; standardized to 1,609.344 m exactly by the 1959 International Yard and Pound Agreement.
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.

Worked examples
Example 1 — Convert 1 mi to sft:
1 × 5279.98944 = 5279.98944 sft
Example 2 — Convert 100 mi to sft:
100 × 5279.98944 = 527998.9439999999 sft
Real-world example — Track athletics distances
A 1-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 mi × 5279.98944 = 5279.98944 sft
Real-world example — Geographic to human-scale conversion
One 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 mi × 5279.98944 = 5279.98944 sft
Real-world example — Lap pacing and route segmentation
Translating a 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 mi × 5279.98944 = 5279.98944 sft
