Please provide values below to Convert inch (US survey) [in] to Earth's equatorial 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 Equatorial Radius?
Earth's Equatorial Radius is the radius of the Earth measured at the Equator. Its value is approximately 6,378.1 kilometers (3,963.2 miles). Due to Earth's rotation, it is slightly larger than the polar radius.
