Brazilian Units Of Measurement
A number of different units of measurement were used in Brazil to measure quantities including length, area, volume, and mass as those units were derived from Portugal and had significant local variances. In 1814, as part of the Portuguese Empire, Brazil adopted the new Portuguese metric system, which was based in the original metric system, but with its units having Portuguese traditional names. This system was not, however, widely adopted and was soon abandoned, with the Portuguese customary units continuing to be used. In 1862, the metric system finally became compulsory in Brazil, and consolidated in 1972.História da Metrologia - Adoção do Sistema Métrico Decimal Acesso em 30 de junho de ...

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 ...

Area
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape A shape or figure is a graphics, graphical representation of an object or its external boundary, outline, or external Surface (mathematics), surface, as opposed to other properties such as color, Surface texture, texture, or material type. A pl ... or planar lamina, while ''surface area'' refers to the area of an open surface or the boundary (mathematics), boundary of a solid geometry, 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 plane curve, curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). The area of a shape can be measured by com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volume
Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units (such as the cubic metre and litre) or by various imperial or US customary units (such as the gallon, quart, cubic inch). The definition of length (cubed) is interrelated with volume. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces. In ancient times, volume is measured using similar-shaped natural containers and later on, standardized containers. Some simple three-dimensional shapes can have its volume easily calculated using arithmetic formulas. Volumes of more complicated shapes can be calculated with integral calculus if a formula exists for the shape's boundary. Zero-, one- and two-dimensional objects have no volume; in fourth and higher dimensions, an analogous concept to the normal vo ...

Mass
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese Customary Units
Portuguese customary units were used in Portugal, Brazil and other parts of the Portuguese Empire until the adoption of the metric system in the 19th century. The various systems of weights and measures used in Portugal until the 19th century combine remote Roman influences with medieval influences from northern Europe and Islam. These influences are obvious in the names of the units. The measurement units themselves were, in many cases, inherited from a distant past. From the Romans, Portugal inherited names like ( la, palmus), ( la, cubitus), , ( la, uncia), ( la, modius), ( la, quartarius), ( la, sextarius). From medieval northern Europe, Portugal inherited names like ( en, mark, french: marc), ( en, bushel, french: boisseau), ( en, tun, french: tonneau), ( en, pint, french: pinte), (Fr. french: chopine), etc. From the Moors, Portugal receive unit names like (Arabic language, Arabic: ), (Arabic language, Arabic: ), (Arabic language, Arabic: ), (Arabic language, Ar ...

Portuguese Empire
The Portuguese Empire ( pt, Império Português), also known as the Portuguese Overseas (''Ultramar Português'') or the Portuguese Colonial Empire (''Império Colonial Português''), was composed of the overseas colonies, factories, and the later overseas territories governed by Portugal. It was one of the longest-lived empires in European history, lasting almost six centuries from the conquest of Ceuta in North Africa, in 1415, to the transfer of sovereignty over Macau to China in 1999. The empire began in the 15th century, and from the early 16th century it stretched across the globe, with bases in North and South America, Africa, and various regions of Asia and Oceania. The Portuguese Empire originated at the beginning of the Age of Discovery, and the power and influence of the Kingdom of Portugal would eventually expand across the globe. In the wake of the Reconquista, Portuguese sailors began exploring the coast of Africa and the Atlantic archipelagos in 1418–1419, u ...

Metric System
The metric system is a system of measurement that succeeded the Decimal, decimalised system based on the metre that had been introduced in French Revolution, France in the 1790s. The historical development of these systems culminated in the definition of the International System of Units (SI) in the mid-20th century, under the oversight of an international standards body. Adopting the metric system is known as ''metrication''. The historical evolution of metric systems has resulted in the recognition of several principles. Each of the fundamental dimensions of nature is expressed by a single base unit (measurement), base unit of measure. The definition of base units has increasingly been realisation (metrology), realised from natural principles, rather than by copies of physical artefacts. For quantities derived from the fundamental base units of the system, units SI derived unit, derived from the base units are used—e.g., the square metre is the derived unit for area, a qu ...

30 De Junho
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Arroba
''Arroba'' is a Portuguese and Spanish custom unit of weight, mass or volume. Its symbol is @. History The word ''arroba'' has its origin in Arabic ''ar-rubʿ'' (الربع) or "quarter," specifically the fourth part (of a quintal), which defined the average load which a donkey could carry. Spain and Portugal In weight it was equal to 32 pounds (14.7 kg) in Portugal and 25 pounds (11.5 kg) in Spain. The unit is still used in Portugal and Spain by cork merchants and pig farmers. Arroba and bushel as weight units are similar (15 kg). Latin America The unit is still used in Brazil by the agricultural sector, mainly in the cotton and cattle business. The modern metric arroba used in these countries in everyday life is defined as . In Colombia, Ecuador, and Peru the arroba is equivalent to . In Bolivia nationally it is equivalent to . However locally there are many different values, ranging from in Inquisivi to in Baures. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quintal
The quintal or centner is a historical unit of mass in many countries which is usually defined as 100 base units, such as pounds or kilograms. It is a traditional unit of weight in France, Portugal, and Spain and their former colonies. It is commonly used for grain prices in wholesale markets in Ethiopia and India, where 1 quintal = 100 kg. In British English, it referred to the hundredweight; in American English, it formerly referred to an uncommon measure of 100 kilograms. Languages drawing its cognate name for the weight from Romance languages include French, Portuguese, Romanian and Spanish , Italian , Esperanto , Polish . Languages taking their cognates from Germanicized ''centner'' include the German , Lithuanian , Swedish , Polish , Russian and Ukrainian (), Estonian and Spanish . Many European languages have come to translate both the imperial and American hundredweight as their cognate form of ''quintal'' or ''centner''. Name The concept has resulted in two ...

Alqueire
''Alqueire'' is a traditional unit of measurement in Portuguese. The term has been documented in Portugal since the 12th century. It is derived from the Arabic word أَكْيَال ''(al-kayl)'', which roughly means 'measure'. It was originally used to measure the amount of dry goods (such as grain) a pack animal could carry, in the form of satchels or baskets. In Portugal, the alqueire was used as a measure of capacity and eventually it was used also as a measure of area of productive land. The spread of Portuguese culture took both meanings of the word to different parts of the world. Usage in Portugal The Arabic ''al-kayl'', used in areas of the Iberian Peninsula under Arab rule, was imported to northern Portugal around the time of the Portuguese County, where it became known as ''alqueire''. The first explicit reference dates from 1111, but the alqueire was already in use in the late 11th century. It was likely that the term ''alqueire'' designated a single well-known measu ...
