Hand
A hand is a unit of length equal to 4 inches.
History/Origin
The hand was originally the width of a man's hand, including the thumb. It was standardized to 4 inches for measuring the height of horses.
Current Use
The hand is still used today to measure the height of horses.
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.
