Caliber
Caliber is a unit of length used to describe the internal diameter of a firearm barrel, typically expressed in hundredths or thousandths of an inch.
History/Origin
The term "caliber" has been used for centuries to describe the size of cannons and firearms.
Current Use
Caliber is the standard unit for designating the bore of firearms in many countries, including the United States.
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.
