Decimalisation
Decimalisation or decimalization (see American and British English spelling differences, spelling differences) is the conversion of a system of currency or of weights and measures to units related by Power of 10, powers of 10. Most countries have decimalised their currencies, converting them from non-decimal sub-units to a decimal system, with one basic currency unit and sub-units that are valued relative to the basic unit by a power of 10 (number), 10, most commonly 100 and exceptionally 1000, and sometimes at the same time, changing the name of the currency and/or the conversion rate to the new currency. Today, only two countries have ''de jure'' non-decimal currencies, these being Mauritania (where 1 Mauritanian ouguiya, ouguiya = 5 khoums) and Madagascar (where 1 Malagasy ariary, ariary = 5 iraimbilanja): however, these currencies are ''de facto'' decimal as the value of both currencies' main unit is now so low that the sub-units are too small to be of any practical use, and ...

Russian Ruble
The ruble or rouble (; Currency symbol, symbol: ₽; ISO 4217, ISO code: RUB) is the currency of the Russia, Russian Federation. Banknotes and coins are issued by the Central Bank of Russia, which is Russia's central bank, monetary authority independent of all other government bodies.wikisource:en:Constitution of Russia#Article 75, Article 75 - Constitution of the Russian Federation (English translation) The ruble is the second-oldest currency in continuous use and the first Decimalisation, decimal currency. The ruble was the currency of the Russian Empire, which was replaced by the Soviet ruble (code: SUR) during the Soviet Union, Soviet period. Following the dissolution of the Soviet Union, by 1992, the Soviet ruble was replaced in the Russian Federation by the Russian ruble (code: RUR) Par value, at par. The Russian ruble then further continued to be used in 11 post-Soviet states, forming a "ruble zone" until 1993. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrication In The United States
Metrication is the process of introducing the International System of Units, also known as SI Units, SI units or the metric system, to replace a jurisdiction's traditional measuring units. United States customary units, U.S. customary units have been defined in terms of metric units since the 19th century, and the SI has been the "preferred system of weights and measures for United States trade and commerce" since 1975 according to United States law. However, conversion was not mandatory and many industries chose not to convert, and U.S. customary units remain in common use in many industries as well as in governmental use (for example, speed limits are still posted in miles per hour). There is government policy and metric (SI) program to implement and assist with metrication; however, there is major social resistance to further metrication. In the U.S., the SI system is used extensively in fields such as science, medicine, electronics, the military, automobile production and ...

Decimal
The decimal numeral system (also called the base-ten positional numeral system and denary or decanary) is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers (''decimal fractions'') of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system is often referred to as ''decimal notation''. A decimal numeral (also often just ''decimal'' or, less correctly, ''decimal number''), refers generally to the notation of a number in the decimal numeral system. Decimals may sometimes be identified by a decimal separator (usually "." or "," as in or ). ''Decimal'' may also refer specifically to the digits after the decimal separator, such as in " is the approximation of to ''two decimals''". Zero-digits after a decimal separator serve the purpose of signifying the precision of a value. The numbers that may be represented in the decimal system are the decimal fractions. That is, fractions of the form , w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrication
Metrication or metrification is the act or process of converting to the metric system of measurement. All over the world, countries have transitioned from local and traditional Unit of measurement, units of measurement to the metric system. This process began in French Revolution, France during the 1790s, and has persistently advanced over two centuries, accumulating into 95% of the world officially only using the International System of Units, modern metric system. Nonetheless, this also highlights that certain countries and sectors are either still transitioning or have chosen not to fully adopt the metric system. Overview The process of metrication is typically initiated and overseen by a country's government, generally motivated by the necessity of establishing a uniform measurement system for effective international cooperation in fields like trade and science. Governments achieve metrication through either mandatory changes to existing units within a specified timeframe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American And British English Spelling Differences
Despite the various list of dialects of English, English dialects spoken from country to country and within different regions of the same country, there are only slight regional variations in English orthography, the two most notable variations being British and American spelling. Many of Comparison of American and British English, the differences between American English, American and British English, British or English in the Commonwealth of Nations, Commonwealth English date back to a time before spelling standards were developed. For instance, some spellings seen as "American" today were once commonly used in Britain, and some spellings seen as "British" were once commonly used in the United States. A "British standard" began to emerge following the 1755 publication of Samuel Johnson's ''A Dictionary of the English Language'', and an "American standard" started following the work of Noah Webster and, in particular, his ''Webster's Dictionary, An American Dictionary of the ...

Electrical Units
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

Units Of Time
A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The SI base unit, base unit of time in the International System of Units (SI), and by extension most of the Western world, is the second, defined as about 9 billion oscillations of the caesium atom. The exact modern SI definition is "[The second] is defined by taking the fixed numerical value of the cesium frequency, , the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1." Historically, many units of time were defined by the movements of astronomical objects. * Sun-based: the year is based on the Earth's orbit, Earth's orbital period around the sun. Historical year-based units include the Olympiad (four years), the lustrum (five years), the indiction (15 years), the decade, the century, and the millennium. * Moon-based: the month is based on the Orbit of the Moon, Moon's orbital per ...

100 (number)
100 or one hundred (Roman numerals, Roman numeral: C) is the natural number following 99 (number), 99 and preceding 101 (number), 101. In mathematics 100 is the square of 10 (number), 10 (in scientific notation it is written as 102). The standard SI prefix for a hundred is "Hecto-, hecto-". 100 is the basis of percentages ( meaning "by the hundred" in Latin), with 100% being a full amount. 100 is a Harshad number in decimal, and also in base-four, a base in-which it is also a self-descriptive number. 100 is the sum of the first nine prime numbers, from 2 through 23 (number), 23. It is also divisible by the number of primes below it, 25 (number), 25. 100 cannot be expressed as the difference between any integer and the total of coprimes below it, making it a noncototient. 100 has a Carmichael function, reduced totient of 20, and an Euler totient of 40. A totient value of 100 is obtained from four numbers: 101 (number), 101, 125 (number), 125, 202 (number), 202, and 250 (number ...

1000 (number)
1000 or one thousand is the natural number following 999 and preceding 1001. In most English-speaking countries, it can be written with or without a comma or sometimes a period separating the thousands digit: 1,000. A group of one thousand units is sometimes known, from Ancient Greek, as a chiliad. A period of one thousand years may be known as a chiliad or, more often from Latin, as a millennium. The number 1000 is also sometimes described as a short thousand in medieval contexts where it is necessary to distinguish the Germanic concept of 1200 as a long thousand. It is the first 4-digit integer. Notation * The decimal representation for one thousand is ** 1000—a one followed by three zeros, in the general notation; ** 1 × 103—in engineering notation, which for this number coincides with: ** 1 × 103 exactly—in scientific normalized exponential notation; ** 1 E+3 exactly—in scientific E notation. * The SI prefix for a thousand units is "kilo-", abbreviate ...
