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.
Chain
A chain is a unit of length equal to 66 feet, or 22 yards.
History/Origin
The chain was developed by English surveyor Edmund Gunter in the early 17th century. It was designed to be a convenient length for surveying land.
Current Use
The chain is still used in some surveying applications and is the length of a cricket pitch.
