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.
Rod
A rod, also known as a perch or pole, is a unit of length equal to 16.5 feet, or 5.5 yards.
History/Origin
The rod has been used as a unit of measurement in England since at least the 13th century. It was a convenient length for measuring land.
Current Use
The rod is now an archaic unit of measurement, though it may still be encountered in old land deeds.
