Italian Units Of Measurement
A variety of units of measurement were used in the various independent Italian states and Italian dependencies of foreign empires up to the unification of Italy in the 19th century. The units to measure length, volume, mass, etc., could differ widely between countries or between towns in a country (e.g. Rome and Ancona), but usually not between a country and its capital. The Kingdom of Sardinia included the island of Sardinia and the continental areas of Piedmont (with the capital Turin) and Liguria (with Genoa). The Kingdom of Naples included the island of Sicily (with Palermo). The Kingdom of Lombardy–Venetia was part of the Austrian Empire, which also shared ruling family with Modena, Parma and Tuscany (capital Florence). The Papal States included the areas of Latium (with the capital Rome), Umbria, Romagna (with Bologna) and the Marches (with Ancona). Milan adopted the metric system in 1803, during the Napoleonic wars, albeit reusing names of older units. After the Congres ...

Units Of Measurement
A unit of measurement, or unit of measure, 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 standardization, standardizes a set of base units and a nomenclature for describing relatively large and small quantities via decimal-based multiplicative unit prefixes. Though the rules governing the metric system have changed over time, the modern definition, the International System of Units (SI), defines the metric prefixes and seven base units: metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), Mole (unit), mole (mol), and candela (cd). An SI derived unit is a named combination of base units such as hertz (cycles per second), Newton (unit), newton (kg⋅m/s2), and tesla (unit), tesla (1 kg⋅s−2⋅A−1) and in the case of Celsius a shifted scale from Kelvin. Certain units have been Non-SI units mentioned in the SI#Units officially accepted for use with the SI, officially accepted for use with the SI. Some of these are decimalised, like the litre and electronvolt, and are considered "metric". Others, like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Culture Of Italy
The culture of Italy encompasses the knowledge, beliefs, arts, laws, and customs of the Italian peninsula throughout history. Italy has been a pivotal center of civilisation, playing a crucial role in the development of Western culture. It was the birthplace of the Ancient Rome, Roman civilisation, the Roman Catholic Church, Catholic Church, and the Renaissance, and significantly contributed to global movements such as the Baroque, Neoclassicism, and Futurism.Cohen, I. Bernard (1965). "Reviewed work: The Scientific Renaissance, 1450-1630, Marie Boas". ''Isis''. 56 (2): 240–42. doi:10.1086/349987. JSTOR 227945.

Litre
The litre ( Commonwealth spelling) or liter ( American spelling) (SI symbols L and l, other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metres (m3). A cubic decimetre (or litre) occupies a volume of (see figure) and is thus equal to one-thousandth of a cubic metre. The original French metric system used the litre as a base unit. The word ''litre'' is derived from an older French unit, the '' litron'', whose name came from Byzantine Greek—where it was a unit of weight, not volume—via Late Medieval Latin, and which equalled approximately 0.831 litres. The litre was also used in several subsequent versions of the metric system and is accepted for use with the SI, despite it not being an SI unit The International System of Units, internationally known by the abbreviation SI (from French ), is the modern form of the metric system and the world's most widely used system of unit ...

Mina (unit)
The mina (; ; ; ; ; ; ) is an ancient Near Eastern unit of weight for silver or gold, equivalent to approximately , which was divided into 60 shekels. The mina, like the shekel, eventually also became a unit of currency. History Sumerian From earliest History of Sumer, Sumerian times, a mina was a unit of weight. At first, talents and shekels had not yet been introduced. By the time of Ur-Nammu (shortly before 2000 BCE), the mina had a value of Talent (weight), talent as well as 60 shekels. The weight of this mina is calculated at , or 570 grams of silver (18 troy ounces). Semitic languages The word mina comes from the ancient Semitic root / 'to count', Akkadian language, Akkadian , (), / (/), (), . It is mentioned in the Bible, where Solomon is reported to have made 300 shields, each with 3 "mina" of gold (), or later after the Edict of Cyrus II of Persia the people are reported to have donated 5000 minas of silver for the reconstruction of Solomon's Temple in Jerusalem ...

Kilogram
The kilogram (also spelled kilogramme) is the base unit of mass in the International System of Units (SI), equal to one thousand grams. It has the unit symbol kg. The word "kilogram" is formed from the combination of the metric prefix kilo- (meaning one thousand) and gram; it is colloquially shortened to "kilo" (plural "kilos"). The kilogram is an SI base unit, defined ultimately in terms of three defining constants of the SI, namely a specific transition frequency of the caesium-133 atom, the speed of light, and the Planck constant. A properly equipped metrology laboratory can calibrate a mass measurement instrument such as a Kibble balance as a primary standard for the kilogram mass. The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water (originally at 0 °C, later changed to the temperature of its maximum density, approximately 4 °C). The current definition of a kilogram agrees with this original defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographical Mile
The geographical mile is an international unit of length determined by 1 minute of arc ( degree) along the Earth's equator. For the international ellipsoid 1924 this equalled 1855.4 metres. '' The American Practical Navigator'' 2017 defines the geographical mile as . Greater precision depends more on the choice of the Earth's radius of the used ellipsoid than on more careful measurement, since the radius of the geoid varies more than along the equator. In any ellipsoid, the length of a degree of longitude at the equator is exactly 60 geographical miles. The Earth's radius at the equator in the GRS80 ellipsoid is , which makes the geographical mile 1,855.3248 m. The rounding of the Earth's radius to metres in GRS80 has an effect of 0.0001 m. The shape of the Earth is a slightly flattened sphere, which results in the Earth's circumference being 0.168% larger when measured around the equator as compared to through the poles. The geographical mile is slightly larger than the naut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pertica (unit)
The pertica (from , measuring rod) was a pre- metric unit of either length or area, with the values varying by location. For a similar unit in Northern Europe, see perch. Ancient Rome In the Ancient Rome, pertica, also called decempeda, was a unit of length, usually equal to 10 Roman feet (''pedes''), or approximately 2.96 meters. The variants of pertica contained 12 and 15 pedes. Isidore of Seville (per Codex Gudianus) states that sometimes a pertica of 10, 12, 15, or 17 pedes was used by agrimensores (Roman land surveyors) to accommodate the richness of the soil and approximately even the yield per unit area. Kidson highlights the near-perfect match between the pertica of 17 pedes and the English version of the perch. The same names, pertica and decempeda, were used for the surveyor's tool, a rod of the corresponding length with subdivision into smaller units, similar to the Ancient Greek ''kalamos''.

Ancient Roman Units Of Measurement
The units of measurement of ancient Rome were generally consistent and well documented. Length The basic unit of Roman linear measurement was the ''pes'' (plural: ''pedes'') or Roman foot. Investigation of its relation to the English foot goes back at least to 1647, when John Greaves published his ''Discourse on the Romane foot''. Greaves visited Rome in 1639, and measured, among other things, the foot measure on the tomb of Titus Statilius Aper, that on the statue of Cossutius formerly in the gardens of Angelo Colocci, the congius of Vespasian previously measured by Villalpandus, a number of brass measuring-rods found in the ruins of Rome, the paving-stones of the Pantheon and many other ancient Roman buildings, and the distance between the milestones on the Appian Way. He concluded that the Cossutian foot was the "true" Roman foot, and reported these values compared to the iron standard of the English foot in the Guildhall in London William Smith (1851) gives a value ...
