A "pica" is a unit of measurement commonly used in typography and desktop publishing to represent the size of text, fonts, and other elements on a printed page. The pica is part of a system of measurement used in the field of typesetting, which involves arranging and designing text for printed materials.
In the pica system:
1 pica (abbreviated as "p") is equal to 12 points. 1 point (abbreviated as "pt") is approximately equal to 1/72nd of an inch.
So, 1 pica is roughly equal to 1/6th of an inch.
This system is based on the traditional point system used in printing, where a point is a very small unit of measurement. Picas and points are still widely used in the design and printing industry, especially when specifying font sizes, line spacing, and other layout details for printed materials like books, magazines, and newspapers.
In digital design and modern desktop publishing software, you can often switch between using picas and points or other units like inches, millimeters, or pixels to set and adjust the layout of text and graphic elements.
A "famn" is a historical unit of length used for measuring depth or distance in nautical and maritime contexts. The term "famn" is of Swedish origin and was widely used in Scandinavian countries and regions with maritime traditions.
The exact length of a famn could vary by region and historical period, but it was typically around 1.8 to 2.2 meters (approximately 5.9 to 7.2 feet). It was commonly used for measuring water depth when navigating, anchoring, or fishing.
Like many historical units of measurement related to nautical and maritime activities, the use of the famn has largely been replaced by modern and standardized systems, such as meters or feet, for precise measurements in navigation and marine industries. However, you may still encounter the term "famn" in historical or traditional maritime contexts.
