Arrátel
The arrátel () was the base unit of weight in the Portuguese customary measurement system.''Dicionário Enciclopédico Lello Universal'', Oporto: Lello & Irmão, 2002. Until the adoption of the metric system in the 19th century, the arrátel was used in Portugal, Brazil and other parts of the Portuguese Empire.MONTEVERDE, Emilio Achilles, ''Manual Encyclopedico para Uzo das Escolas de Instrucção Primaria'', Lisboa: Imprensa Nacional, 1861. The real value of the arrátel fluctuated during the Middle Ages. Before king Pedro I, the main arrátel seems to have been an arrátel of 12.5 ounces. With Pedro I, the official arrátel increased to 14 ounces. Finally, the Portuguese arrátel was fixed at 16 ounces by decree of King Manuel I in 1499. This arrátel, which was kept as the national standard until the introduction of the metric system, was similar to the Spanish libra. Arratel values * 13th century: Arratel = 12½ ''onças'' (ounces) = 25/32 ''libras'' = 0,3596 kg; * 15th ce ... [...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 ...

Base Unit (measurement)
A base unit (also referred to as a fundamental unit) is a unit adopted for measurement of a ''base quantity''. A base quantity is one of a conventionally chosen subset of physical quantities, where no quantity in the subset can be expressed in terms of the others. The SI base units, or ''Systeme International d'unites'', consists of the metre, kilogram, second, ampere, Kelvin, mole and candela. A secondary unit for the same quantity is a ''derived unit''; for example, when used with the International System of Units, the gram is a derived unit, not a base unit. Background In the language of measurement, ''physical quantities'' are quantifiable aspects of the world, such as time, distance, velocity, mass, temperature, energy, and weight, and ''units'' are used to describe their magnitude or quantity. Many of these quantities are related to each other by various physical laws, and as a result the units of a quantities can be generally be expressed as a product of powers of other uni ...

Weight
In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a Euclidean vector, vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force. Yet others define it as the magnitude of the reaction (physics), reaction force exerted on a body by mechanisms that counteract the effects of gravity: the weight is the quantity that is measured by, for example, a spring scale. Thus, in a state of free fall, the weight would be zero. In this sense of weight, terrestrial objects can be weightless: ignoring Drag (physics), air resistance, the famous apple falling from the tree, on its way to meet the ground near Isaac Newton, would be weightless. The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton (unit), newton. For example, an object with a mass of one kilogram ...

Lello & Irmão
The Livraria Lello & Irmão, commonly known in English as the Lello Bookstore, is a bookstore located in the civil parish of Cedofeita, Santo Ildefonso, Sé, Miragaia, São Nicolau e Vitória, in the northern Portuguese municipality of Porto. Along with Bertrand in Lisbon, it is one of the oldest bookstores in Portugal and frequently rated among the top bookstores in the world (placing third in lists by guidebook publisher Lonely Planet and ''The Guardian''). History In 1869, the ''Livraria Internacional de Ernesto Chardron'' was founded, from a shop on ''Rua dos Clérigos'' by the Frenchman . Following its founder's death, at the age of 45, the firm was sold to ''Lugan & Genelioux Sucessores''. Alternately, in 1881, José Lello along with his brother-in-law created the firm ''David Pereira & Lello''. But, the following year, after the death of David Lourenço Pereira, the establishment began to be operated as ''José Pinto de Sousa Lello & Irmão'', when he partnered with hi ...

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 ...

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 ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedro I Of Portugal
Peter I (Portuguese: ''Pedro I'', ; 8 April 1320 – 18 January 1367), called the Just (''o Justiceiro'') or the Cruel (''o Cruel''), was King of Portugal from 1357 until his death. He was the third but only surviving son of Afonso IV of Portugal and his wife, Beatrice of Castile. Early life In 1328, Peter's father, Afonso IV arranged for the marriage of his eldest daughter, Maria, to Alfonso XI of Castile. However, soon after their marriage Alfonso began a long affair with the beautiful and newly widowed Leonor de Guzman. Maria bore Alfonso a son in 1334, who ultimately became Peter of Castile, but after the Castilian king refused to end his affair Maria returned home to Portugal in 1335. Alfonso had been married once before, to his cousin's daughter, Constanza Manuel (granddaughter of James II of Aragon). Alfonso had the marriage annulled in 1327, after only two years, to clear the way for marriage to Maria. This angered his cousin Juan Manuel, Prince of Villena, a powerful ...

The #International avoirdupois ounce, avoirdupois ounce (exactly ) is Pound (mass)#Avoirdupois pound, avoirdupois pound; this is the United States customary units, United States customary and British imperial unit, imperial ounce. It is primarily used in the United States to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere. Although the avoirdupois ounce is the mass measure used for most purposes, the 'troy ounce' of exactly is used instead for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc. The term 'ounce' is also used in other contexts: * The #Ounce-force, ounce-force is a measure of force (see below). * The fluid ounce is a m ...

Manuel I Of Portugal
Manuel I (; 31 May 146913 December 1521), known as the Fortunate ( pt, O Venturoso), was King of Portugal from 1495 to 1521. A member of the House of Aviz, Manuel was Duke of Beja and Viseu prior to succeeding his cousin, John II of Portugal, as monarch. Manuel ruled over a period of intensive expansion of the Portuguese Empire owing to the numerous Portuguese discoveries made during his reign. His sponsorship of Vasco da Gama led to the Portuguese discovery of the sea route to India in 1498, resulting in the creation of the Portuguese India Armadas, which guaranteed Portugal's monopoly on the spice trade. Manuel began the Portuguese colonization of the Americas and Portuguese India, and oversaw the establishment of a vast trade empire across Africa and Asia. He was also the first monarch to bear the title: ''By the Grace of God, King of Portugal and the Algarves, this side and beyond the Sea in Africa, Lord of Guinea and the Conquest, Navigation and Commerce in Ethiopia, A ...
