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 Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
