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.
A kilometer (km) is a unit of length used in the metric system of measurement. It is equal to one thousand meters, which is the base unit of length in the International System of Units (SI). Therefore, 1 kilometer is equal to 1,000 meters, 100,000 centimeters, 1,000,000 millimeters, or 0.621371 miles.
Kilometers are commonly used for measuring longer distances on Earth, such as the length of roads, the distance between cities, and the dimensions of geographical features like rivers, mountains, and coastlines. They are also used in various sports and outdoor activities, such as running, cycling, and hiking, to express distances. Kilometers are a convenient unit of measurement for everyday use in many countries around the world that use the metric system.
