Point
A point is a unit of typographical measurement. In the context of printing, it is approximately 1/72 of an inch.
History/Origin
The point system of typography was developed in the 18th century. It provides a standardized way to measure font sizes and leading.
Current Use
The point is the standard unit for measuring font sizes in both print and digital media.
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.
