pt is the font unit.

pt stands for point, which means "point" in Chinese. It is commonly used in software design, typesetting and printing industries. (Recommended learning: CSS video tutorial)
In conventional typesetting, font size is measured in "points". The size of movable type is called "font size", and the width of letters is called "font width", 1 point = 0.376 mm = 1.07 British and American points = 0.0148 feet = 0.1776 inches.
"Point" is the unit for measuring font size, not the so-called unit of length or mass.
pound refers to the transliteration of point. The correct Chinese translation should be "point" or "point".
In typesetting and printing, the height and width of text form the size of the text to be calculated in unique units of measurement, namely points and ciceros. Point (pt) is commonly used as the unit in modern times.
In 1675, French Fournier invented the point system, which was later improved by Paris font dealer Firmin Didot to establish a modern typesetting measurement system. Later, Dido improved the point system. Gradually it was adopted throughout Europe. Today, the Dido point system is mainly used in Europe, while the Anglo-American point system is mainly used in England and the United States. The "point" in both point systems is the smallest unit of measurement.
We usually hear the word "pound" in a certain word as a common name, and professionals call it "point". Point is abbreviated as pt.
Example: 4pt, which is 4 points. Therefore, everyone must be careful not to translate the weight unit "pound" as a literal unit.
