Feet (US survey)

A foot (US survey) is a unit of length used in land surveying and mapping in the United States. One foot (US survey) is defined as exactly 1200/3937 meters, which is approximately 0.3048006096 meters or about 0.3048 meters.

The US survey foot is slightly different from the international foot, which is defined as exactly 0.3048 meters. The difference is due to historical measurement standards and is used in specific contexts such as land surveying and engineering in the United States.

US survey feet are used primarily in the United States for property measurement, land surveying, and mapping, ensuring consistency in measurements within these fields.

Earth's equatorial radius

The Earth's equatorial radius is the distance from the Earth's center to the equator. One Earth's equatorial radius is approximately 6,378.1 kilometers or about 3,963.2 miles.

The equatorial radius is the longest radius of the Earth due to its equatorial bulge, caused by the planet's rotation. This bulge results in a slightly larger radius at the equator compared to the polar radius.

The Earth's equatorial radius is used in geodesy, cartography, and satellite navigation to define the Earth's shape and for accurate measurements of distances and areas on the Earth's surface. It provides a key parameter for understanding Earth's dimensions and its gravitational field.
