Vietnamese Units Of Measurement
Vietnamese units of measurement ( vi, hệ đo lường Việt Nam) are the largely decimal units of measurement traditionally used in Vietnam until metrication. The base unit of length is the ''thước'' (chữ Nôm: 𡱩; lit. "ruler") or ''xích'' (). 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'' for the English 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 equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Units Of Measurement
A unit of measurement 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. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical 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. A multitude of System of measurement, systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.

Metric System
The metric system is a system of measurement that succeeded the Decimal, decimalised system based on the metre that had been introduced in French Revolution, France in the 1790s. The historical development of these systems culminated in the definition of the International System of Units (SI) in the mid-20th century, under the oversight of an international standards body. Adopting the metric system is known as ''metrication''. The historical evolution of metric systems has resulted in the recognition of several principles. Each of the fundamental dimensions of nature is expressed by a single base unit (measurement), base unit of measure. The definition of base units has increasingly been realisation (metrology), realised from natural principles, rather than by copies of physical artefacts. For quantities derived from the fundamental base units of the system, units SI derived unit, derived from the base units are used—e.g., the square metre is the derived unit for area, a qu ...

History
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the History of writing#Inventions of writing, invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an Discipline (academia), academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the historiography, nature of history as an end in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Li (unit)
''Li'' (, ''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. There is also another ''li'' (Traditional: 釐, Simplified: 厘, ''lí'') that indicates a unit of length of a ''chi'', but it is used much less commonly. This ''li'' is used in the People's Republic of China as the equivalent of the ''centi-'' prefix in metric units, thus ''limi'' ( 厘米, límǐ) for centimeter. The tonal difference makes i ...

Vietnamese Alphabet
The Vietnamese alphabet ( vi, chữ Quốc ngữ, lit=script of the National language) is the modern Latin writing script or writing system for Vietnamese language, Vietnamese. It uses the Latin script based on Romance languages originally developed by Portuguese alphabet, Portuguese missionary Francisco de Pina (1585 – 1625). The Vietnamese alphabet contains 29 letters, including seven letters using four diacritics: ''ă'', ''â''/''ê''/''ô'', ''ơ''/''ư'', ''đ''. There are an additional five diacritics used to designate Tonal language, tone (as in ''à'', ''á'', ''ả'', ''ã'', and ''ạ''). The complex vowel system and the large number of letters with diacritics, which can stack twice on the same letter (e.g. ''nhất'' meaning "first"), makes it easy to distinguish the Vietnamese orthography from other writing systems that use the Latin alphabets, Latin script. The Vietnamese system's use of diacritics produces an accurate transcription for Tonal Languages, tones desp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hanoi
Hanoi or Ha Noi ( or ; vi, Hà Nội ) is the capital and second-largest city of Vietnam. It covers an area of . It consists of 12 urban districts, one district-leveled town and 17 rural districts. Located within the Red River Delta, Hanoi is the cultural and political centre of Vietnam. Hanoi can trace its history back to the third century BCE, when a portion of the modern-day city served as the capital of the historic Vietnamese nation of Âu Lạc. Following the collapse of Âu Lạc, the city was part of Han China. In 1010, Vietnamese emperor Lý Thái Tổ established the capital of the imperial Vietnamese nation Đại Việt in modern-day central Hanoi, naming the city Thăng Long (literally 'Ascending Dragon'). Thăng Long remained Đại Việt's political centre until 1802, when the Nguyễn dynasty, the last imperial Vietnamese dynasty, moved the capital to Huế. The city was renamed Hanoi in 1831, and served as the capital of French Indochina from 1902 to 1945. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
