Danish Units Of Measurement
The Danes started with a system of units based on a Greek ''pous'' ("foot") of which they picked up through trade in the late Bronze Age/early Iron Age. Some early standards of measure can be recovered from measured drawings made of the Hjortspring boat, which though dating to the early Iron Age exemplifies plank-built vessels of the late Bronze Age and the Nydam ship. Thwarts are typically spaced about 3 ''fod'' apart. King Christian V of Denmark introduced an office to oversee weights and measures, a ''justervæsen''. This was first led by the royal mathematician Ole Rømer, who established a national system of weights and measures on May 1st, 1683. Rømer's system, which he updated in 1698, was based on the Rhine foot. Its definitions included the following: * the Danish mile as 24,000 Rhineland feet (i.e. 4 minutes of arc latitude) * the Danish pound (''pund'') as of the weight of a cubic Rhineland foot of water (499.7 g) * the Danish ell (''alen'') as 2 Rhineland feet ( ...

Sjælland
Zealand ( da, Sjælland ) at 7,031 km2 is the largest and most populous island in Denmark proper (thus excluding Greenland and Disko Island, which are larger in size). Zealand had a population of 2,319,705 on 1 January 2020. It is the 13th-largest island in Europe by area and the 4th most populous. It is connected to Sprogø and Funen by the Great Belt Fixed Link and to Amager by several bridges in Copenhagen. Indirectly, through the island of Amager and the Øresund Bridge, it is also linked to Scania in Sweden. In the south, the Storstrøm Bridge and the Farø Bridges connect it to Falster, and beyond that island to Lolland, from where the Fehmarnbelt Tunnel to Germany is planned. Copenhagen, the capital of Denmark, with a population between 1.3 and 1.4 million people in 2020, is located mostly on the eastern shore of Zealand and partly on the island of Amager. Other cities on Zealand include Roskilde, Hillerød, Næstved, Helsingør, Slagelse, Køge, Holbæk a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historical Weights And Measures
A system of measurement is a collection of units of measurement and rules relating them to each other. Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce. Systems of measurement in use include the International System of Units or (the modern form of the metric system), the British imperial system, and the United States customary system. History The French Revolution gave rise to the metric system, and this has spread around the world, replacing most customary units of measure. In most systems, length (distance), mass, and time are ''base quantities''. Later science developments showed that an electromagnetic quantity such as electric charge or electric current could be added to extend the set of base quantities. Gaussian units have only length, mass, and time as base quantities, with no separate electromagnetic dimension. Other quantities, such as power and speed, are derived from the base set: for example, spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weights And Measures
A unit of measurement is a definite 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 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. In trade, weights and measures is often a subject of governmental regulation, to ensure fairness and transparency. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pint
The pint (, ; symbol pt, sometimes abbreviated as ''p'') is a unit of volume or capacity in both the imperial unit, imperial and United States customary units, United States customary measurement systems. In both of those systems it is traditionally one eighth of a gallon. The British imperial pint is about 20% larger than the American pint because Comparison of the imperial and US customary measurement systems, the two systems are defined differently. Almost all other countries have standardized on the metric system, so although some of them still also have traditional units called pints (such as for beverages), the volume varies by regional custom. The imperial pint (≈) is used in the United Kingdom and Ireland and to a limited extent in Commonwealth of Nations, Commonwealth nations. In the United States, two kinds of pint are used: a liquid pint (≈) and a less-common dry pint (≈). Other Dominion , former British colonies, such as Canada, Australia, South Africa and New Z ...

Barrel Of Land
A barrel of land (Danish language, Danish: ''tønde land'', Norwegian language, Norwegian: ''tønneland'', Swedish language, Swedish: ''tunnland'', Finnish language, Finnish: ''tynnyrinala'') is a Scandinavian unit of area. The word may originate from the area of fields one could seed with a barrel of grain seeds. The acre is the equivalent Anglo-Saxons, Anglo-Saxon unit. Because the barrel sizes varied by country, the area unit does too. One barrel can be approximated as half a hectare. Per country Denmark In Denmark the ''tønde'' was used as an official area unit until the introduction of the metric system in 1907. A ''tønde'' was divided in 8 ''skæpper''. A ''skæppe'' was divided into 4 ''fjerdingkar'' and a ''fjerdingkar'' into 3 ''album''. Norway A ''tønneland'' was divided in 4 mål. Nowadays a ''mål'' corresponds to 1,000 square meters in everyday speech. Sweden The unit was officially surveyed and standardized in the 1630s, and set to 14,000 Swedish square ells, i.e ...

Apothecaries' System
The apothecaries' system, or apothecaries' weights and measures, is a historical system of mass and volume units that were used by physicians and apothecaries for medical prescriptions and also sometimes by scientists."Medicinal-Gewicht, Apotheker-Gewicht ist dasjenige Gewicht, nach welchem Aerzte und Apotheker die Quantitäten der Arzneimittel bestimmen. Nur an wenigen Orten werden beide Arten der Gewichte unterschieden und Medicinalgewicht bei dem Einkauf der Arzneiwaaren im Großen von dem Apothekergewicht bei der Anfertigung und dem Einzel-Verkauf in den Apotheken getrennt. In diesem Fall ist das Medicinalgewicht dem gewöhnlichen Landesgewicht beinahe oder völlig gleich und das Pfund wird dann in 16 Unzen getheilt. Bei dem eigentlichen Apothekergewicht aber nimmt man nur einen Theil des Landesgewichts und theilt dieses Pfund in 12 Unzen oder 96 Drachmen oder 288 Scrupel oder 5760 Gran oder 7452 Aß." The English version of the system is closely related to the English troy sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line (length)
The line (abbreviated L or l or ‴ or lin.) was a small English unit of length, variously reckoned as , , , or of an inch. It was not included among the units authorized as the British Imperial system in 1824. Size The line was not recognized by any statute of the English Parliament but was usually understood as of a barleycorn, which itself was recognized by statute as of an inch. The line was eventually decimalized as of an inch, without recourse to barleycorns. The US button trade uses the same or a similar term but defined as one-fortieth of the US-customary inch (making a button-maker's line equal to 0.635 mm). In use Botanists formerly used the units (usually as inch) to measure the size of plant parts. Linnaeus's ''Philosophia botanica'' (1751) includes the Linea in its summary of units of measurements, defining it as "Linea una Mensurae parisinae"; Stearns gives its length as 2.25 mm. Even after metrication, British botanists continued to employ tool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inch
Measuring tape with inches The inch (symbol: in or ″) is a unit of length in the British imperial and the United States customary systems of measurement. It is equal to yard or of a foot. Derived from the Roman uncia ("twelfth"), the word ''inch'' is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb. Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm. Name The English word "inch" ( ang, ynce) was an early borrowing from Latin ' ("one-twelfth; Roman inch; Roman ounce"). The vowel change from Latin to Old English (which became Modern English ) is known as umlaut. The consonant change from the Latin (spelled ''c'') to English is palatalisation. Both were features of Old English phonology; see and fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foot (length)
The foot ( feet), standard symbol: ft, is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, , is a customarily used alternative symbol. Since the International Yard and Pound Agreement of 1959, one foot is defined as 0.3048 meters exactly. In both customary and imperial units, one foot comprises 12 inches and one yard comprises three feet. Historically the "foot" was a part of many local systems of units, including the Greek, Roman, Chinese, French, and English systems. It varied in length from country to country, from city to city, and sometimes from trade to trade. Its length was usually between 250 mm and 335 mm and was generally, but not always, subdivided into 12 inches or 16 digits. The United States is the only industrialized nation that uses the international foot and the survey foot (a customary unit of length) in preference to the meter in its commercial, engineer ...

Palm (length)
The palm is an obsolete anthropic unit of length, originally based on the width of the human palm and then variously standardized. The same name is also used for a second, rather larger unit based on the length of the human hand. The width of the palm was a traditional unit in Ancient Egypt, Israel, Greece, and Rome and in medieval England, where it was also known as the hand,. handbreadth, or handsbreadth.. The only commonly discussed "palm" in modern English is the biblical palm of ancient Israel. The length of the hand—originally the Roman "greater palm"—formed the palm of medieval Italy and France. In Spanish customary units ' or ' was the palm, while ' was the span, the distance between an outstretched thumb and little finger. In Portuguese ' or ' was the span. History Ancient Egypt The Ancient Egyptian palm ( egy, shesep) has been reconstructed as about . The unit is attested as early as the reign of Djer, third pharaoh of the First Dynasty, and appears on many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptolemy
Claudius Ptolemy (; grc-gre, Πτολεμαῖος, ; la, Claudius Ptolemaeus; AD) was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the '' Almagest'', although it was originally entitled the ''Mathēmatikē Syntaxis'' or ''Mathematical Treatise'', and later known as ''The Greatest Treatise''. The second is the ''Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the ''Apotelesmatika'' (lit. "On the Effects") but more commonly known as the '' Tetrábiblos'', from the Koine Greek meaning "Four Books", or by its Latin equivalent ''Quadrip ...
