Earth's polar radius

The Earth's polar radius is the distance from the Earth's center to the poles. One Earth's polar radius is approximately 6,356.8 kilometers or about 3,949.9 miles.

The polar radius is shorter than the equatorial radius due to the Earth's oblate spheroid shape, which results from its rotation causing a bulge at the equator and a flattening at the poles.

The Earth's polar radius is used in geodesy, cartography, and satellite navigation to accurately describe the Earth's shape and dimensions. It is essential for understanding Earth's gravitational field, polar regions, and measurements related to the planet's overall geometry.

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.
