Wa (unit)
Wa ( th, วา , also ''waa'' or ''wah'', abbreviated ) is a unit of length, equal to two metres (2 m) or four 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's outstretched arms. The 1833 Siamese-American Treaty of Amity and Commerce, reads, " heSiamese fathom...being computed to contain 78 English or American inches, corresponding to 96 Siamese inches." The length then would have been equivalent to a modern 1.981 metres. Since 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 International metric system (SI). Wa also occurs as a colloquialism for "square wa" (tarang wa) a unit of area abbreviated or .) As with many terms normally written in the Thai alphabet, romanization of Thai causes spelling variants such as ''waa'' and ''wah''. See also *Thai units of measuremen ...

Length
Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a 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 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, and width, breadth or depth. Height is used when there is a base from which vertical measurements can be taken. Width or breadth usually refer to a shorter dimension when length is the longest one. Depth is used for the third dimension of a three dimensional object. Length is the measure of one spatial dimension, whereas area is a measure of two dimensions (length square ...

Tarang Wa
A tarang wa ( th, ตารางวา, , ) or square wa, sometimes transliterated as 'waa' or 'wah' is a unit of area used in Thailand for measuring land or property. It is defined as the area of a square whose sides measure exactly one wa (two metres), equivalent to four square metres. Although its current size is precisely derived from the metre, it is neither part of nor recognized by the modern metric system, the International System (SI). The square wa equals 1/100 ngaan or 1/400 rai, two units of area frequently used in Thailand. It also equals 1/25 are, another metre-derived unit of area not officially part of the SI. As with many terms normally written with the Thai alphabet, there are many variant transliterations into English, e.g. dta-raang waa and tarang wah.

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 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 SI and non-SI units. Metric system SI The base unit in the International System of Units (SI) is the metre, defined as "the length of the path travelled by light in vacuum during a time interval of seconds." It is approximately equal to . Other SI units are derived from the metre by adding prefixes, as in millimetre or kilometre, thus producing systematic decimal multiples and submultiples of the base unit that span many orders of magnitude. For example, a kilometre is . Non-SI In the centimetre–gram–second system of units, the basic unit of length is the centimetre, or ...

Royal Institute Of Thailand
The Royal Society ( th, ราชบัณฑิตยสภา, , ) is the national academy of Thailand in charge of academic works of the government. The secretariat of the society is the Office of the Royal Society ( th, สำนักงานราชบัณฑิตยสภา, ), formerly known as the Royal Institute ( th, ราชบัณฑิตยสถาน, ). The office is an independent agency under the prime minister's supervision. The Royal Society was established on 19 April 1926 and was dissolved on 31 March 1934. The dissolved society was split into the Royal Institute and the Fine Arts Department. On 14 February 2015, the Royal Institute was reorganised. Its administrative council became the Royal Society, whilst the institute itself became the office of the society. According to the present structure, the members of the Royal Society are of three types: associate fellows, fellows, and honorary fellows. The associate fellows are experts selected and ...

Thai Units Of Measurement
Thailand adopted the metric system on 17 December 1923.Minutes of the 7th General Conference on Weights and Measures
1927, page 69
However, old Thai units are still in common use, especially for measurements of land. 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 mea ...

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 ...

Thai Alphabet
The Thai script ( th, อักษรไทย, ) is the abugida used to write Thai, Southern Thai and many other languages spoken in Thailand. The Thai alphabet itself (as used to write Thai) has 44 consonant symbols ( th, พยัญชนะ, ''phayanchana''), 16 vowel symbols ( th, สระ, ''sara'') that combine into at least 32 vowel forms and four tone diacritics ( th, วรรณยุกต์ or วรรณยุต, or ) to create characters mostly representing syllables. Although commonly referred to as the "Thai alphabet", the script is in fact 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 alphabet is der ...

Colloquialism
Colloquialism (), also called colloquial language, everyday language or general parlance, is the style (sociolinguistics), linguistic style used for casual (informal) communication. It is the most common functional style of speech, the idiom normally employed in conversation and other informal context (language use), contexts. Colloquialism is characterized by wide usage of Interjection, interjections and other expressive devices; it makes use of non-specialist terminology, and has a rapidly changing lexicon. It can also be distinguished by its usage of formulations with incomplete logical and syntax (linguistics), syntactic ordering. A specific instance of such language is termed a ''colloquialism''. The most common term used in dictionaries to label such an expression is ''colloquial''. Explanation Colloquialism or general parlance is distinct from public speaking, formal speech or formal writing.colloquial. (n.d.) Dictionary.com Unabridged (v 1.1). Retrieved September 10, 2008 ...

Metre
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately  km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). 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 path travelled by light in a vacuum in of a second. After the 2019 redefi ...

Thai Solar Calendar
The Thai solar calendar ( th, ปฏิทินสุริยคติ, , "solar calendar") was adopted by King Chulalongkorn (Rama V) in 1888 CE as the Siamese version of the Gregorian calendar, replacing the Thai lunar calendar as the legal calendar in Thailand (though the latter is still also used, especially for traditional and religious events). Years are now counted in the Buddhist Era (B.E.): , () which is 543 years ahead of the Gregorian calendar. Years The Siamese generally used two calendars, a ''sacred'' and a ''popular'' ( ''vulgar'' in the classical sense). The vulgar or 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.) Rattanakosin Era King Chulalongkorn decreed a change in vulgar reckoning to the '' Rattanakosin Era'' ...
