Units Of Volume
A unit of volume is a unit of measurement for measuring volume or capacity, the extent of an object or space in three dimension (mathematics), dimensions. Units of capacity may be used to specify the volume of fluids or bulk goods, for example water, rice, sugar, grain or flour. Units According to the International System of Units, SI system, the base unit (measurement), base unit for measuring length is the metre. The SI unit of volume is thus the cubic metre, which is a derived unit, where: at nist.gov. Retrieved 29 June 2022. 1 m3 = 1 m • 1 m • 1 m.

Pompeji 6 Hohlmaße Aus Glas
Pompeii (, ) was an ancient city located in what is now the ''comune'' of Pompei near Naples in the Campania region of Italy. Pompeii, along with Herculaneum and many villas in the surrounding area (e.g. at Villa Boscoreale, Boscoreale, Stabiae), was buried under of volcanic ash and pumice in the Eruption of Mount Vesuvius in 79 AD. Largely preserved under the ash, the excavated city offered a unique snapshot of Culture of ancient Rome, Roman life, frozen at the moment it was buried, although much of the detailed evidence of the everyday life of its inhabitants was lost in the excavations. It was a wealthy town, with a population of ca. 11,000 in AD 79, enjoying many fine public buildings and luxurious private houses with lavish decorations, furnishings and works of art which were the main attractions for the early excavators. Organic remains, including wooden objects and human bodies, were interred in the ash. Over time, they decayed, leaving voids that archaeologists found ...

Hoppus
The hoppus cubic foot (or ‘hoppus cube’ or ‘h cu ft’) was the standard volume measurement used for timber in the British Empire and countries in the British sphere of influence before the introduction of metric units. It is still used in the hardwood trade of some countries. This volume measurement was developed to estimate what volume of a round log would be usable timber after processing, in effect attempting to ‘square’ the log and allow for waste. The hoppus ton (HT) was also a traditionally used unit of volume in British forestry. One hoppus ton is equal to 50 hoppus feet or 1.8027 cubic metres. Some shipments of tropical hardwoods, especially shipments of teak from Myanmar (Burma), are still stated in hoppus tons. History The English surveyor Edward Hoppus introduced the unit in his 1736 manual of practical calculations. The tables include reference to stone as well as timber, as stone can similarly suffer wastage during processing into regular pieces. Calculat ...

Physical Quantity
A physical quantity is a physical property of a material or system that can be quantified by measurement. A physical quantity can be expressed as a ''value'', which is the algebraic multiplication of a ' Numerical value ' and a ' Unit '. For example, the physical quantity of mass can be quantified as '32.3 kg ', where '32.3' is the numerical value and 'kg' is the Unit. A physical quantity possesses at least two characteristics in common. # Numerical magnitude. # Units Symbols and nomenclature International recommendations for the use of symbols for quantities are set out in ISO/IEC 80000, the IUPAP red book and the IUPAC green book. For example, the recommended symbol for the physical quantity ''mass'' is ''m'', and the recommended symbol for the quantity ''electric charge'' is ''Q''. Subscripts and indices Subscripts are used for two reasons, to simply attach a name to the quantity or associate it with another quantity, or index a specific component (e.g., row or colum ...

Metre Convention
The Metre Convention (french: link=no, Convention du Mètre), also known as the Treaty of the Metre, is an international treaty that was signed in Paris on 20 May 1875 by representatives of 17 nations (Argentina, Austria-Hungary, Belgium, Brazil, Denmark, France, Germany, Italy, Peru, Portugal, Russia, Spain, Sweden and Norway, Switzerland, Ottoman Empire, United States of America, and Venezuela). The treaty created the International Bureau of Weights and Measures (BIPM), an intergovernmental organization under the authority of the General Conference on Weights and Measures ( CGPM) and the supervision of the International Committee for Weights and Measures (CIPM), that coordinates international metrology and the development of the metric system. As well as founding the BIPM and laying down the way in which the activities of the BIPM should be financed and managed, the Metre Convention established a permanent organizational structure for member governments to act in common accord ...

History Of Measurement
The earliest recorded systems of weights and measures originate in the 3rd or 4th millennium BC. Even the very earliest civilizations needed measurement for purposes of agriculture, construction and trade. Early standard units might only have applied to a single community or small region, with every area developing its own standards for lengths, areas, volumes and masses. Often such systems were closely tied to one field of use, so that volume measures used, for example, for dry grains were unrelated to those for liquids, with neither bearing any particular relationship to units of length used for measuring cloth or land. With development of manufacturing technologies, and the growing importance of trade between communities and ultimately across the Earth, standardized weights and measures became critical. Starting in the 18th century, modernized, simplified and uniform systems of weights and measures were developed, with the fundamental units defined by ever more precise methods ...

Faggot (unit)
A faggot, in the meaning of "bundle", is an archaic English unit applied to bundles of certain items. Alternate spellings in Early Modern English include ''fagate, faget, fagett, faggott, fagot, fagatt, fagott, ffagott,'' and ''faggat''. A similar term is found in other languages (e.g. Latin: ''fascis''). Background Sometimes called a short faggot, a faggot of sticks equals a bundle of wood sticks or billets that is in length and in circumference. The measurement was standardised in ordinances by 1474. A small short faggot was also called a nicket. A brush-faggot (sometimes shortened to brush) was a bundle of similar size made of brushwood. A long faggot of sticks equals a bundle larger than long. In a book on slang used at Winchester College fire-dogs were fire basket (andirons) that could hold long faggots, and half-faggots were smaller andirons that could only hold short faggots and were later converted for use with coal. A long faggot was also called a kidd faggot,Yaxley, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pulpwood
Pulpwood is timber with the principal use of making wood pulp for paper production. Applications * Trees raised specifically for pulp production account for 15% of world pulp production, old growth forests 9% and second- and third- and more generation forests account for the balance. Reforestation is practiced in most areas, so trees are a renewable resource. * Pulpwood is also used as the raw material for some wood products, such as oriented strand board (OSB). * There is an increasing demand for pulpwood as a source of bio-energy for burning and baking into charcoal. Properties The fiber length of the cellulose fiber is the most important parameter of the pulpwood and determines what it may be used for. The first separation is into softwood and hardwood, that have long and short fibers respectively. In paper production fiber from softwood give tensile strength and fibers from hardwood give opacity.

Cord (unit)
The cord is a unit of measure of dry volume used to measure firewood and pulpwood in the United States and Canada. A cord is the amount of wood that, when "racked and well stowed" (arranged so pieces are aligned, parallel, touching and compact), occupies a volume of . This corresponds to a well-stacked woodpile high, wide, and deep; or any other arrangement of linear measurements that yields the same volume. The name ''cord'' probably comes from the use of a cord or string to measure it. The cord-foot was a US unit of volume for stacked firewood, four feet long, four feet wide and one foot high—equal to one eighth of a cord. Symbol for the unit was cd-ft. Definitions In Canada, the cord is legally defined by Measurement Canada. The cord is one of three legal standards for the sale of firewood in Canada: stacked cubic metre (or stere), cubic foot, and cord. The preferred unit of measurement for firewood is the stacked cubic metre. In the United States, the cord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Board Foot
The board foot or board-foot is a unit of measurement for the volume of lumber in the United States and Canada. It equals the volume of a length of a board, one foot wide and thick. Board foot can be abbreviated as FBM (for "foot, board measure"), BDFT, or BF. A thousand board feet can be abbreviated as MFBM, MBFT, or MBF. Similarly, a million board feet can be abbreviated as MMFBM, MMBFT, or MMBF. Until 1970s in Australia and New Zealand the terms super foot and superficial foot were used with the same meaning. One board foot equals: * 1 ft × 1 ft × 1 in * 12 in × 12 in × 1 in * 144 in3 * 1/12 ft3 * ≈ * ≈ * ≈ or steres * 1/1980 Petrograd Standard of board The board foot is used to measure rough lumber (before drying and planing with no adjustments) or planed/surfaced lumber. An example of planed lumber is softwood 2 × 4 lumber sold by large lumber retailers. The 2 × 4 is actually only , but the dimensions for the lumber when purchased wholesal ...

Firewood
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly processed and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets or chips. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as hardwood or softwood. Firewood is a renewable resource. However, demand for this fuel can outpace its ability to regenerate on a local or regional level. Good forestry practices and improvements in devices that use firewood can improve local wood supplies. Moving firewood long distances can potentially transport diseases and invasive species. History For most of human history firewood was the main fuel, until the use of coal spread during the Industrial Revolution. As such, access to firewood was a valued resource, wood botes or the right to gather firewood being a significant aspect of many medieval leases. As late as 19th C America, Thoreau ...
