Thước
Vietnamese units of measurement () are the largely decimal units of measurement traditionally used in Vietnam until metrication. The base unit of length is the ''thước'' (; lit. "ruler") or ''xích'' ( vi-hantu, 尺). Some of the traditional unit names have been repurposed for metric units, such as ''thước'' for the metre, while other traditional names remain in translations of imperial units, such as ''dặm Anh (English "dặm")'' for the mile. History Originally, many ''thước'' of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), the traditional system of units had at least two ''thước'' of different lengths before 1890, the ''thước ta'' (lit. "our ruler") or ''thước mộc'' ("wooden ruler"), equal to , and the ''thước đo vải'' ("ruler for measuring cloth"), equal to . According to historian Nguyễn Đình Đầu, the ''trường xích'' and ''điền xích'' were both equal to , while according to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chi (unit)
The chi (Tongyong Pinyin chih) is a traditional Chinese unit of length. Although it is often translated as the "", its length was originally derived from the distance measured by a human hand, from the tip of the thumb to the tip of the forefinger, and is similar to the ancient span. It first appeared during China's Shang dynasty approximately 3,000 years ago and has since been adopted by other East Asian cultures such as Japan ('' shaku''), Korea (''ja/cheok''), and Vietnam (''thước''). Its present value is standardized at around , although the exact standards vary among the mainland of the People's Republic of China, its special administrative region of Hong Kong, and Taiwan. In its ancient and modern forms, the chi is divided into 10 smaller units known as cun (the "Chinese inch"). 10 chi are equal to 1 zhàng. Modern values In mainland China, the ''chi'' is been defined as exactly 1/3 of a meter, i.e., . However, in Hong Kong the corresponding unit, pronounced ''t ...

Units Of Measurement
A unit of measurement, or unit of measure, is a definite magnitude (mathematics), magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

The metre (symbol m) is a unit of length that represents a definite predetermined length. For instance, when referencing "10 metres" (or 10 m), what is actually meant is 10 times the definite predetermined length called "metre". The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to the present.

History
History is the systematic study of the past, focusing primarily on the Human history, human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on Primary source, primary and secondary sources to reconstruct past events and validate interpretations.

Li (unit)
''Li'' or ri (, ''lǐ'', or , ''shìlǐ''), also known as the Chinese mile, is a traditional Chinese unit of distance. The ''li'' has varied considerably over time but was usually about one third of an English mile and now has a standardized length of a half-kilometer (). This is then divided into 1,500 chi or "Chinese feet". The character 里 combines the characters for "field" ( 田, ''tián'') and "earth" ( 土, ''tǔ''), since it was considered to be about the length of a single village. As late as the 1940s, a "li" did not represent a fixed measure but could be longer or shorter depending on the ''effort'' required to cover the distance. This traditional unit, in terms of historical usage and distance proportion, can be considered the East Asian counterpart to the Western league unit. However, in English '' league'' commonly means "3 miles." There is also another '' li'' (Traditional: 釐, Simplified: 厘, ''lí'') that indicates a unit of length of a ''chi'', but i ...

Area
Area is the measure of a region's size on a surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while '' surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). Two different regions may have the same area (as in squaring the circle); by synecdoche, "area" sometimes is used to refer to the region, as in a " polygonal area". The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area o ...

Chữ Nôm
Chữ Nôm (, ) is a logographic writing system formerly used to write the Vietnamese language. It uses Chinese characters to represent Sino-Vietnamese vocabulary and some native Vietnamese words, with other words represented by new characters created using a variety of methods, including phono-semantic compounds. This composite script was therefore highly complex and was accessible to the less than five percent of the Vietnamese population who had mastered written Chinese. Although all formal writing in Vietnam was done in classical Chinese until the early 20th century (except for two brief interludes), chữ Nôm was widely used between the 15th and 19th centuries by the Vietnamese cultured elite for popular works in the vernacular, many in verse. One of the best-known pieces of Vietnamese literature, '' The Tale of Kiều'', was written in chữ Nôm by Nguyễn Du.
