Handbreadth
A handbreadth is an ancient unit of length, based on the width of the hand at the knuckles, excluding the thumb. It is typically about 3 inches.
History/Origin
The handbreadth has been used as a unit of measurement in many cultures throughout history.
Current Use
The handbreadth is an obsolete unit of measurement.
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.
