Convert inch (US survey) [in] to Earth's polar radius
Please provide values below to Convert inch (US survey) [in] to Earth's polar radius, or vice versa.
What is a US Survey Inch?
The US survey inch (1/39.37 meter ≈ 2.540005 cm) was slightly longer than the international inch (2.54 cm). Used in all American engineering drawings until 2023, its difference caused measurable discrepancies in large-scale projects.
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.
