A "ken" is not a widely recognized unit of measurement in modern systems. However, the term "ken" is more commonly used as a noun or verb in English and has a different meaning.
As a noun, "ken" refers to one's range of sight, perception, or understanding. For example, you might say, "Beyond my ken," to mean something is beyond your understanding or knowledge.
As a verb, "ken" means to understand, perceive, or know. For instance, you might use it in a sentence like, "I cannot ken the complexity of this issue."
In these contexts, "ken" is used to describe one's ability to perceive or comprehend something, rather than a unit of measurement. If you have a specific context in which "ken" is being used as a unit of measurement, please provide more details, and I'll do my best to assist you further.
A "point" (abbreviated as "pt") is a unit of measurement commonly used in typography and desktop publishing to specify the size of text, fonts, and other elements on a printed or digital page. The point is part of a system of measurement used in the field of typesetting, which involves arranging and designing text for printed materials.
In the point system:
1 point (abbreviated as "pt") is equal to approximately 1/72nd of an inch. This means that there are approximately 72 points in 1 inch.
Points are used to define the size of fonts, leading (line spacing), and other layout details in printed materials. For example, when you specify a font size of 12 points, you are indicating that the height of the characters in that font will be roughly 1/6th of an inch or about 4.23 millimeters.
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 points and other units like picas, inches, millimeters, or pixels to set and adjust the layout of text and graphic elements.
