Wa (unit)
Wa ( , also ''waa'' or ''wah'', abbreviated ) is a unit of length, equal to two metres (2 m) or four :th:ศอก (หน่วยความยาวไทย), sok (.) ''Wa'' as a verb means to outstretch (one's) arms to both sides, which relates to the fathom's distance between the fingertips of a Man (word), man's outstretched arms. The 1833 Siamese-American Treaty of Amity and Commerce, reads, "[The] Siamese fathom...being computed to contain 78 English or American inches, corresponding to 96 :th:นิ้ว (หน่วยความยาวไทย), Siamese inches." The length then would have been equivalent to a modern 1.981 metres. Since Metrication#Status by country/region, conversion to the metric system in 1923, the length as derived from the metre is precisely two metres, but the unit is neither part of nor recognized by the modern SI, International metric system (SI). Wa also occurs as a colloquialism for "square wa" (tarang wa) a unit of area abbreviated or .) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Length
Length is a measure of distance. In the International System of Quantities, length is a quantity with Dimension (physical quantity), dimension distance. In most systems of measurement a Base unit (measurement), base unit for length is chosen, from which all other units are derived. In the International System of Units (SI) system, the base unit for length is the metre. Length is commonly understood to mean the most extended size, dimension of a fixed object. However, this is not always the case and may depend on the position the object is in. Various terms for the length of a fixed object are used, and these include height, which is vertical length or vertical extent, width, breadth, and depth. ''Height'' is used when there is a base from which vertical measurements can be taken. ''Width'' and ''breadth'' usually refer to a shorter dimension than ''length''. ''Depth'' is used for the measure of a third dimension. Length is the measure of one spatial dimension, whereas area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarang Wa
The ''rai'', ''ngan'', and ''tarang wa'' or square ''wa'' are customary Thai units of area, used in the measurement of land. They are defined as exactly 1,600, 400, and 4 square metres, respectively (17,222, 4,306, and 43 sq ft). The ''tarang wa'' (square ''wa'', ''tarang'' meaning 'grid') is derived from the area of a square with sides of 1 '' wa'' (the Thai fathom). 1 ''ngan'' ('work') is equal to 100 square ''wa'', and 1 ''rai'' ('field' or 'plantation') equals 4 ''ngan'' or 1 square '' sen''. The units were standardised in square metres when Thailand (then Siam) adopted the metric system in 1923, although the Royal Survey Department was already reported in 1908 to be using the metre-based conversion for its cadastral maps A cadastre or cadaster ( ) is a comprehensive recording of the real estate or real property's metes-and-bounds of a country.Jo Henssen, ''Basic Principles of the Main Cadastral Systems in the World,'/ref> Often it is represented graphically in ....

Units Of Length
A unit of length refers to any arbitrarily chosen and accepted reference standard for measurement of length. The most common units in modern use are the metric system, metric units, used in every country globally. In the United States the U.S. customary units are also in use. British Imperial units are still used for some purposes in the United Kingdom and some other countries. The metric system is sub-divided into International System of Units, SI and non-SI units. History Metric system SI The SI base unit, base unit in the International System of Units (SI) is the meter, defined as "the length of the path travelled by speed of light, light in vacuum during a time interval of seconds." It is approximately equal to . Other SI units are derived from the meter by adding Metric prefix, prefixes, as in millimeter or kilometer, thus producing systematic decimal multiples and submultiples of the base unit that span many orders of magnitude. For example, a kilometer is . Non ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Institute Of Thailand
The Royal Society (; ; ) is the national academy of Thailand responsible for academic works of the Thai government. The secretariat of the society is the Office of the Royal Society (; ), formerly known as the Royal Institute (; ). The office is an independent agency of the government, but subject to the supervision of the prime minister. Members of the society consist of associate fellows, fellows, and honorary fellows. The associate fellows are academicians selected and appointed by the society. The fellows are associate fellows selected by the society and appointed by the monarch upon advice of the prime minister. The honorary fellows are prominent academicians selected by the society and appointed in the same way as the fellows. The society is known for its roles in the planning and regulation of the Thai language, as well as its many publications, particularly the '' Royal Institute Dictionary'', the official and prescriptive dictionary of the Thai language, and the R ...

Thai Units Of Measurement
Before metrication, the traditional system of measurement used in Thailand employed anthropic units. Some of these units are still in use, albeit standardised to SI/metric measurements. When the Royal Thai Survey Department began cadastral survey in 1896, Director R. W. Giblin, F.R.G.S., noted, "It so happens that 40 metres or 4,000 centimetres are equal to one ''sen''," so all cadastral plans are plotted, drawn, and printed to a scale of 1:4,000. The square ''wa'', ''ngan'' and ''rai'' are still used in measurements of land area. The ''baht'' is still used as a unit of measurement in gold trading. However, one ''baht'' of 96.5% gold bullion is defined as 15.16 grams rather than the generic standard of 15 grams. The ''baht'' has also become the name of the currency of Thailand, which was originally fixed to the corresponding mass of silver.

Romanization Of Thai
There are many systems for the romanization of the Thai language, i.e. representing the language in Latin script. These include systems of transliteration, and transcription. The most seen system in public space is Royal Thai General System of Transcription (RTGS)—the official scheme promulgated by the Royal Thai Institute. It is based on spoken Thai, but disregards tone, vowel length and a few minor sound distinctions. The international standard ISO 11940 is a transliteration system, preserving all aspects of written Thai adding diacritics to the Roman letters. Its extension ISO 11940-2 defines a simplified transcription reflecting the spoken language. It is almost identical to RTGS. Libraries in English-speaking countries use the ALA-LC Romanization. In practice, often non-standard and inconsistent romanizations are used, especially for proper nouns and personal names. This is reflected, for example, in the name Suvarnabhumi Airport, which is spelled based on direct transl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thai Alphabet
The Thai script (, , ) is the abugida used to write Thai, Southern Thai and many other languages spoken in Thailand. The Thai script itself (as used to write Thai) has 44 consonant symbols (, ), 16 vowel symbols (, ) that combine into at least 32 vowel forms, four tone diacritics ( or , or ), and other diacritics. Although commonly referred to as the ''Thai alphabet'', the script is not a true alphabet but an abugida, a writing system in which the full characters represent consonants with diacritical marks for vowels; the absence of a vowel diacritic gives an implied 'a' or 'o'. Consonants are written horizontally from left to right, and vowels following a consonant in speech are written above, below, to the left or to the right of it, or a combination of those. History The Thai script is derived from the Sukhothai script, which itself is derived from the Old Khmer script (, ''akson khom''), which is a southern Brahmic style of writing derived from the south Indian Pa ...

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 ...

Colloquialism
Colloquialism (also called ''colloquial language'', ''colloquial speech'', ''everyday language'', or ''general parlance'') is the linguistic style used for casual and informal communication. It is the most common form of speech in conversation among persons in friendship, familial, intimate, and other informal contexts. Colloquialism is characterized by the usage of figurative language, contractions, filler words, interjections, and other informalities such as slang. In contrast to formal and professional communications, colloquial speech does not adhere to grammar and syntax rules and thus may be considered inappropriate and impolite in situations and settings where etiquette is expected or required. It has a rapidly changing lexicon and can also be distinguished by its usage of formulations with incomplete logical and syntactic ordering.

Metre
The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of of a second, where the second is defined by a hyperfine transition frequency of caesium. The metre was originally defined in 1791 by the French National Assembly as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's polar circumference is approximately . In 1799, the metre was redefined in terms of a prototype metre bar. The bar used was changed in 1889, and in 1960 the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the pat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thai Solar Calendar
The Thai solar calendar (, , "solar calendar") was adopted by King Chulalongkorn (Rama V) in 1888 Common Era, CE as the Siamese version of the Gregorian calendar, replacing the Thai lunar calendar as the legal Thai calendar (though the latter is still also used, especially for traditional and religious events). Years are now counted in the Buddhist Era (B.E.): (lit. 'Shaka era, era of the Shaka Buddha') which is 543 years ahead of the Gregorian calendar. Years The Siamese generally used two calendars, a ''sacred'' and a ''popular'' (wikt:vulgar#Adjective, ''vulgar'' in the classical sense). The vulgar or Chula Sakarat, minor era (, ''chula sakarat'') was thought to have been instituted when the worship of Gautama was first introduced, and corresponds to the traditional Burmese calendar (abbreviated ME or BE, the latter not to be confused with the abbreviation for the Buddhist Era, which is the sacred era.)
