The US Survey Foot is a unit of length historically used for land surveying in the United States.
It is very close in length to the international foot, equaling approximately 1.000002 international feet (ft). The plural form is US Survey Feet.
The origin of the US Survey Foot dates back to the Mendenhall Order of 1893. This order defined the relationship between the meter and US customary units.
It established that 1 meter is precisely equal to 39.37 inches. From this relationship, the US Survey Foot was derived, defined as 1200/3937 meters.
This definition differs slightly from the international foot, which was established in 1959 and is defined as exactly 0.3048 meters.
To simplify measurements and prevent confusion, the National Institute of Standards and Technology (NIST) and the National Geodetic Survey (NGS) made a critical change.
They officially retired the U.S. Survey Foot on December 31, 2022.
Surveying and mapping applications in the United States will now use the international foot. This critical change helps unify the National Spatial Reference System (NSRS) and prevents costly errors in large-scale projects.
While the difference between a US Survey Foot and an international foot is minuscule—only about two parts per million—it becomes significant over large distances.
For every mile, the discrepancy adds up to approximately 1/8 inch.
This minor error may not be significant for a backyard fence. However, for massive construction projects and infrastructure development, such as bridges that cross state lines, the accumulated error can lead to severe misalignments and costly mistakes.
The meter (m) is the foundational unit of length in the metric system, a standard of measurement used worldwide.
Simply put, it's used to measure the distance or separation between things.
The plural form is meters.
The original definition of the meter dates back to 1793.
The French Academy of Sciences established it as exactly one ten-millionth (1/10,000,000) of the distance from the North Pole to the Equator (measured along a line passing through Paris).
This ambitious goal was to create a universal unit based on a natural feature of the Earth itself.
Today, the modern definition is far more precise and is based on a universal constant: the speed of light.
Since 1983, the meter has been officially defined as the distance that light travels in a vacuum in exactly 1/299,792,458 of a second.
This modern definition ensures that the meter is incredibly stable and can be accurately reproduced in any lab around the world.
As one of the seven base units in the International System of Units (SI), the meter is essential for calculating many other derived units.
For example, the meter is used to measure:
The meter serves as a fundamental unit in scientific and engineering measurements worldwide.
