Pica


A pica is a unit of length commonly used in typography and printing to measure font sizes, line lengths, and spacing. It is equal to 1/6 of an inch, or exactly 12 points in the point system.


Key facts:



  • 1 pica = 1/6 inch β‰ˆ 4.233 millimeters



  • 1 pica = 12 points



  • Used primarily in graphic design, printing, and typesetting



  • Helps standardize the measurement of fonts, columns, and layouts



The pica remains a fundamental unit in desktop publishing and print design, helping maintain consistency in text and page formatting.



Earth Equatorial Radius


The Earth's equatorial radius is the distance from the center of the Earth to the equator. It represents the Earth's radius measured along the equatorial plane.



  • Its value is approximately 6,378.1 kilometers (about 3,963.2 miles).



  • The Earth is not a perfect sphere but an oblate spheroid, so the equatorial radius is slightly larger than the polar radius.



  • This radius is important for geodesy, satellite orbits, and mapping.



Key facts:



  • Equatorial radius β‰ˆ 6,378.1 km



  • Larger than polar radius due to Earth's flattening at the poles



  • Used in Earth sciences, navigation, and space missions



Understanding the Earth's equatorial radius helps in accurate modeling of the planet’s shape and gravitational field.
