Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
Span (Cloth)
A span is an obsolete unit of length, typically about 9 inches, based on the distance between the tip of the thumb and the tip of the little finger when the hand is fully extended.
History/Origin
The span has been used as a unit of measurement for thousands of years in many different cultures.
Current Use
The span is no longer a standard unit of measurement.
