Q:Information:  - Typographic units are the units of measurement used in typography or typesetting. Traditional typometry units are different from familiar metric units because they were established in the early days of printing. Though most printing is digital now, the old terms and units have persisted.  - The thumb is the first digit of the hand. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is pollex (compare "hallux" for big toe), and the corresponding adjective for thumb is pollical.  - The pica is a typographic unit of measure corresponding to 1  72 of a foot , or 1  6 of an inch . The pica contains 12 point units of measure . The pica originated around 1785 , when François - Ambroise `` L'éclat '' Didot ( 1730 -- 1804 ) refined the typographic measures system created by Pierre Simon Fournier le Jeune ( 1712 -- 1768 ) . He replaced the traditional measures of cicéro , Petit - Roman , and Gros - Text with `` ten - point '' , `` twelve - point '' , etc. To date , in printing these three pica measures are used : The French pica of 12 Didot points ( also called cicéro ) generally is : 12 × 0.376 = 4.512 mm ( 0.177 in ) . The American pica measure of 0.013837 ft. ( 1  72.27 ft ) . Thus , a pica is 0.166044 in . ( 4.2175 mm ) The contemporary computer pica is 1  72 of the International foot of 1959 , i.e. 4.233 mm or 0.166 in . Note that these definitions are different from a typewriter 's pica setting , which denotes a type size of ten characters per horizontal inch . Usually , pica measurements are represented with an upper - case `` P '' with an upper - right - to - lower - left virgule ( slash ) starting in the upper right portion of the `` P '' and ending at the lower left of the upright portion of the `` P '' ; essentially drawing a virgule ( / ) through a `` P '' . ( P ) Likewise , points are represented with number of points before a lower - case `` p '' , for example , 5p represents `` 5 points '' , and 6P2p represents `` 6 picas and 2 points '' , and 1P1 represents `` 13 points '' , which is converted to a mixed fraction of 1 pica and 1 point . Publishing applications such as Adobe InDesign and QuarkXPress represent pica measurements with whole - number picas left of a lower - case `` p '' , followed by the points number , for example : 5p6 , represents 5 picas and 6 points , or 5 picas . Cascading Style Sheets defined by the World Wide Web Consortium use `` pc '' as the abbreviation for pica ( 1/6 of an inch ) , and `` pt '' for point ( 1/72 of an inch ) .  - The metric system is an internationally agreed decimal system of measurement. It was originally based on the and the introduced by the French First Republic in 1799, but over the years the definitions of the metre and the kilogram have been refined, and the metric system has been extended to incorporate many more units. Although a number of variants of the metric system emerged in the late nineteenth and early twentieth centuries, the term is now often used as a synonym for "SI" or the "International System of Units"the official system of measurement in almost every country in the world.  - Middle English (ME) is collectively the varieties of the English language spoken after the Norman Conquest (1066) until the late 15th century; scholarly opinion varies but the Oxford English Dictionary specifies the period of 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages.  - The yard (abbreviation: yd) is an English unit of length, in both the British imperial and US customary systems of measurement, that comprises 3 feet or 36 inches. It is by international agreement in 1959 standardized as exactly 0.9144 meters. A metal yardstick originally formed the physical standard from which all other units of length were officially derived in both English systems.  - The Germanic languages are a branch of the Indo-European language family spoken natively by a population of approximately 500 million people mainly in North America, Oceania, Southern Africa, and Central, Western and Northern Europe. It is the third most spoken Indo-European subdivision, behind Italic and Indo-Iranian, and ahead of Balto-Slavic languages.  - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets.  - Typography is the art and technique of arranging type to make written language legible, readable, and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line-spacing (leading), and letter-spacing (tracking), and adjusting the space between pairs of letters (kerning). The term typography is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process. Type design is a closely related craft, sometimes considered part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers. Typography also may be used as a decorative device, unrelated to communication of information.  - Modern humans ("Homo sapiens", primarily ssp. "Homo sapiens sapiens") are the only extant members of Hominina tribe (or human tribe), a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; manual dexterity and increased tool use, compared to other animals; and a general trend toward larger, more complex brains and societies.  - An inch (abbreviation: in or ) is a unit of length in the imperial and United States customary systems of measurement now formally equal to yard but usually understood as of a foot. Derived from the Roman uncia ("twelfth"), "inch" is also sometimes used to translate related units in other measurement systems, usually understood as deriving from the width of the human thumb. Traditional standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and reckoned as exactly 2.54cm. Name. The English word "inch" was an early borrowing from Latin "" ("one-twelfth; Roman inch; Roman ounce") not present in other Germanic languages. The vowel change from Latin /u/ to English // is known as umlaut. The consonant change from the Latin /k/ to English /t/ or // is palatalisation. Both were features of Old English phonology. "Inch" is cognate with "ounce", whose separate pronunciation and spelling reflect its reborrowing in Middle English from Anglo-Norman "unce" and "ounce".  - In geometric measurements, length is the most extended dimension of an object. In the International System of Quantities, length is any quantity with dimension distance. In other contexts "length" is the measured dimension of an object. For example, it is possible to cut a length of a wire which is shorter than wire thickness.  - An ounce (abbreviated oz; apothecary symbol: ) is a unit of mass used in most British derived customary systems of measurement. It is most pervasive in the retail sale of groceries in the United States, but is also used in many other matters of domestic and international trade. Similar customary uses include recipes in cookbooks and sales of bulk dry goods.  - Typesetting is the composition of text by means of arranging physical types or the digital equivalents. Stored letters and other symbols (called sorts in mechanical systems and glyphs in digital systems) are retrieved and ordered according to a language's orthography for visual display. Typesetting requires the prior process of designing a font (which is widely but erroneously confused with and substituted for typeface). One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission.
