What is the Earth's equatorial radius?

It is the distance from Earth's center to the equator measured along the equatorial plane, standardized by the WGS84 model as 6,378.137 kilometers.

Why convert Earth's equatorial radius to feet?

Converting to feet helps express global scale distances in a familiar unit commonly used in engineering, construction, and aviation.

Is this unit conversion suitable for everyday measurements?

No, the Earth's equatorial radius is extremely large and typically not used for everyday length measurements.
