A unit prefix is a specifier or mnemonic that is prepended to units of measurement to indicate multiples or fractions of the units. Units of various sizes are commonly formed by the use of such prefixes. The prefixes of the metric system, such as ''kilo'' and ''milli'', represent multiplication by powers of ten. In information technology it is common to use binary prefixes, which are based on powers of two. Historically, many prefixes have been used or proposed by various sources, but only a narrow set has been recognised by standards organisations. Metric prefixes The prefixes of the metric system precede a basic unit of measure to indicate a decadic multiple and fraction of a unit. Each prefix has a unique symbol that is prepended to the unit symbol. Some of the prefixes date back to the introduction of the metric system in the 1790s, but new prefixes have been added, and some have been revised. The International Bureau of Weights and Measures has standardised twenty me ... [...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.

A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic. Each prefix has a unique symbol that is prepended to any unit symbol. The prefix ''kilo-'', for example, may be added to ''gram'' to indicate ''multiplication'' by one thousand: one kilogram is equal to one thousand grams. The prefix ''milli-'', likewise, may be added to ''metre'' to indicate ''division'' by one thousand; one millimetre is equal to one thousandth of a metre. Decimal multiplicative prefixes have been a feature of all forms of the metric system, with six of these dating back to the system's introduction in the 1790s. Metric prefixes have also been used with some non-metric units. The SI prefixes are metric prefixes that were standardised for use in the International System of Units (SI) by the International Bureau of Weights and Measures (BIPM) in resolutions dating from 1960 to 2022.

Myriad
A myriad (from Ancient Greek grc, μυριάς, translit=myrias, label=none) is technically the number 10,000 (ten thousand); in that sense, the term is used in English almost exclusively for literal translations from Greek, Latin or Sinospheric languages (Chinese, Japanese, Korean, and Vietnam), or when talking about ancient Greek numerals. More generally, a myriad may be used in colloquial vernaculars to imply an indefinitely large number. History The Aegean numerals of the Minoan and Mycenaean civilizations included a single unit to denote tens of thousands. It was written with a symbol composed of a circle with four dashes . In Classical Greek numerals, a myriad was written as a capital mu: Μ, as lower case letters did not exist in Ancient Greece. To distinguish this numeral from letters, it was sometimes given an overbar: . Multiples were written above this sign, so that for example would equal 4,582×10,000 or 45,820,000. The etymology of the word ''myriad'' itself ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myria (metric Prefix)
Myria- (symbol my) is a now obsolete decimal metric prefix denoting a factor of 104 (ten thousand). It originates from the Greek μύριοι (''mýrioi'') (myriad). The prefix was part of the original metric system adopted by France in 1795, but was not adopted when the SI prefixes were internationally adopted by the 11th CGPM conference in 1960. In 1685 John Wallis proposed the usage of myrio. Also, in 19th century English it was sometimes spelled myrio, in line with a puristic opinion by Thomas Young. The ''myriametre'' (10 km) is occasionally encountered in 19th-century train tariffs, or in some classifications of wavelengths as the adjective '' myriametric''. The French ''mesures usuelles'' (1812-1839) did not include any units of length greater than the ''toise'', but the ''myriametre'' remained in use throughout this period. (Website based on ''Alte Meß- und Währungssysteme aus dem deutschen Sprachgebiet'', .) In Sweden and Norway, the ''myriametre'' is still ...
