US Survey Miles to Yards (mi (US) to yd)

1 US survey mile equals 1,760.00352 yards (rounded).

1 US survey mile = 1,760.00352 yards

How to convert US survey miles to yards

To convert US survey miles to yards, multiply the number of US survey miles by 1,760.00352. The factor is rounded to 10 significant digits. To go the other way, multiply yards by 0.0005681806818 (rounded).

yards = US survey miles × 1,760.00352

Example: 10 US survey miles = 17,600.0352 yards.

About these units

US Survey Mile (mi (US))

US land surveyHistorical unit (no longer in standard use)

5,280 US survey feet (about 1,609.347 m). Slightly longer than the international mile, used in US land surveys until 2022.

Because it is built from 5,280 survey feet, this mile inherits the survey foot's tiny excess and comes to about 1,609.347 m, against exactly 1,609.344 m for the international mile. The gap is under 1/8 inch, or 3.2 mm, per mile, and one international mile equals 0.999998 survey miles. In US law the formal statute mile was the survey mile, though everyday usage treats the two as the same.

Over a single trip the difference vanishes, but State Plane Coordinate Systems can stretch across hundreds of miles, where a few millimetres per mile accumulate into something a surveyor must account for. For that reason surveyors kept the survey mile long after the international foot took over elsewhere. In October 2019 the National Geodetic Survey and NIST announced that the survey foot and mile would be retired from 1 January 2023, and NIST says the unit now survives only for historic and legacy data. Maps and deeds written before then still use it.

1 US survey mile = 1,609.347219 meters (approximately).

Yard (yd)

US & ImperialCurrent unit

3 feet or 36 inches, exactly 0.9144 meters. Used for sports fields, fabric and short distances in the US and UK.

Yard descends from the Old English gerd or gyrd, meaning a branch, stave or measuring rod. It first appears in the late seventh-century laws of Ine of Wessex, though there it names a tax unit, the yardland. Around 959 to 963 King Edgar ordered that the measure held at Winchester be used throughout his realm, the earliest record of a prototype. A story that Henry I fixed the yard as the distance from his nose to his thumb is later folklore, and the true origin, whether pace, cubit or waist, remains speculative.

Britain defined the Imperial Standard Yard in 1824 as the distance between two marks on a brass rod at 62 degrees Fahrenheit. A fire in 1834 damaged the standard, a replacement was made in 1845, and the Weights and Measures Act 1855 recognized it. The 1959 international agreement then fixed the yard at exactly 0.9144 meter. Today it measures American and Canadian football fields, association football pitches and cricket pitches, appears on UK road signs for short distances, and is still used to sell fabric in the US and UK.

1 yard = 0.9144 meters (exactly).
