The nautical league in the United Kingdom is a unit of nautical measurement that is traditionally defined as three nautical miles. A nautical mile, also known as a sea mile, is a unit of distance used in navigation and marine contexts. It is based on the circumference of the Earth and is approximately equal to one minute of latitude along a meridian.
In the United Kingdom and many other maritime nations, a nautical league is considered to be equal to three nautical miles, which is roughly equivalent to 5.556 kilometers or 3.452 statute miles (land miles). This measurement is used for maritime and navigational purposes, especially for calculating distances at sea.
It's worth noting that the use of traditional nautical measurements like leagues has largely been replaced by more standardized and precise modern navigation methods that rely on nautical miles and other internationally recognized units. Nonetheless, these older units of measurement may still be referenced in historical documents or traditional maritime contexts.
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.
