What is a US Survey Foot?
The US survey foot (1200/3937 meters ≈ 0.3048006 m) was the standard American measurement until 2023. Slightly longer than the international foot (0.3048 m), it originated from the 1893 Mendenhall Order and was crucial for the Public Land Survey System that mapped the American West.
What is Earth's Polar Radius?
Earth's Polar Radius is the radius of the Earth measured from its center to the North or South Pole. Its value is approximately 6,356.8 kilometers (3,950.7 miles), slightly smaller than the equatorial radius due to Earth's oblate shape.
