The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is a British imperial and US customary unit of weight or mass. Its value differs between the US and British imperial systems. The two values are distinguished in American English as the "short" and "long" hundredweight and in British English as the "cental" and the "imperial hundredweight".

Under both conventions, there are 20 hundredweight in a ton, producing a "short ton" of 2,000 pounds and a "long ton" of 2,240 pounds.

Quintal

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.

Imperial units

Imperial units

The imperial system of units, imperial system or imperial units is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments.

Weight

Weight

In science and engineering, the weight of an object is the force acting on the object due to acceleration or gravity.

Mass

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 when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies.

American English

American English

American English, sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the United States and in most circumstances is the de facto common language used in government, education and commerce. Since the 20th century, American English has become the most influential form of English worldwide.

British English

British English

British English is, according to Oxford Dictionaries, "English as used in Great Britain, as distinct from that used elsewhere". More narrowly, it can refer specifically to the English language in England, or, more broadly, to the collective dialects of English throughout the British Isles taken as a single umbrella variety, for instance additionally incorporating Scottish English, Welsh English, and Northern Irish English. Tom McArthur in the Oxford Guide to World English acknowledges that British English shares "all the ambiguities and tensions [with] the word 'British' and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity".

Ton

Ton

Ton is the name of any one of several units of measure. It has a long history and has acquired several meanings and uses.

Short ton

Short ton

The short ton is a measurement unit equal to 2,000 pounds (907.18 kg). It is commonly used in the United States, where it is known simply as a ton, although the term is ambiguous, the single word being variously used for short, long, and metric ton.

Long ton

Long ton

The long ton, also known as the imperial ton or displacement ton, is the name for the unit called the "ton" in the avoirdupois system of weights or Imperial system of measurements. It was standardised in the 13th century. It is used in the United Kingdom and several other Commonwealth of Nations countries alongside the mass-based metric tonne defined in 1799, as well as in the United States for bulk commodities.

History

The hundredweight has had many values. In England in around 1300, different "hundreds" (centum in Medieval Latin) were defined. The Weights and Measures Act 1835 formally established the present imperial hundredweight of 112 lb.

The United States and Canada came to use the term "hundredweight" to refer to a unit of 100 lb. This measure was specifically banned from British use—upon risk of being sued for fraud—by the Weights and Measures Act 1824 but in 1879 the measure was legalised under the name "cental" in response to legislative pressure from British merchants importing wheat and tobacco from the United States.[3]

Medieval Latin

Medieval Latin

Medieval Latin was the form of Literary Latin used in Roman Catholic Western Europe during the Middle Ages. In this region it served as the primary written language, though local languages were also written to varying degrees. Latin functioned as the main medium of scholarly exchange, as the liturgical language of the Church, and as the working language of science, literature, law, and administration.

Fraud

Fraud

In law, fraud is intentional deception to secure unfair or unlawful gain, or to deprive a victim of a legal right. Fraud can violate civil law or criminal law, or it may cause no loss of money, property, or legal right but still be an element of another civil or criminal wrong. The purpose of fraud may be monetary gain or other benefits, for example by obtaining a passport, travel document, or driver's license, or mortgage fraud, where the perpetrator may attempt to qualify for a mortgage by way of false statements.

Wheat

Wheat

Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus Triticum ; the most widely grown is common wheat. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis.

Tobacco

Tobacco

Tobacco is the common name of several plants in the genus Nicotiana of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used in some countries.

The short hundredweight is commonly used in the US in the sale of livestock and some cereal grains[4] and oilseeds, paper, and concrete additives and on some commodities in futures exchanges.[5]

A few decades ago, commodities weighed in terms of long hundredweight included cattle, cattle fodder, fertilizers, coal, some industrial chemicals, other industrial materials, and so on. However, since increasing metrication in most English-speaking countries, it is now less used. Church bell ringers use the unit commonly,[6] although church bell manufacturers are increasingly moving over to the metric system.[7]

Older blacksmiths' anvils are often stamped with a three-digit number indicating their total weight in hundredweight, quarter-hundredweight (28 lb, abbreviated qr), and pounds. Thus, an anvil stamped "1.1.8" will weigh 148 lb (112 lb + 28 lb + 8 lb).[8]

The Imperial hundredweight is used as a measure of vehicle weight in the Bailiwick of Guernsey. It was also previously used to indicate the maximum recommended carrying load of vans and trucks, such as the Ford Thames 5 & 7 cwt vans[9] and the 8, 15, 30 and 60 cwt Canadian Military Pattern trucks.[10]

Alderney

Alderney

Alderney is the northernmost of the inhabited Channel Islands. It is part of the Bailiwick of Guernsey, a British Crown dependency. It is 3 miles (5 km) long and 1+1⁄2 miles (2.4 km) wide.

Livestock

Livestock

Livestock are the domesticated animals raised in an agricultural setting to provide labor and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, goats, and pigs. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The latter is likely due to the fact that fish products are not governed by the USDA, but by the FDA.

Cereal

Cereal

A cereal is any grass cultivated for the edible components of its grain, which is composed of an endosperm, a germ, and a bran. Cereal grain crops are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. They include wheat, rye, oats, and barley. Edible grains from other plant families, such as buckwheat, quinoa and chia, are referred to as pseudocereals.

Paper

Paper

Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes.

Concrete

Concrete

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is being done to try to reduce the emissions or make concrete a source of carbon sequestration, and increase recycled and secondary raw materials content into the mix to achieve a circular economy. Concrete is expected to be a key material for structures resilient to climate disasters, as well as a solution to mitigate the pollution of other industries, capturing wastes such as coal fly ash or bauxite tailings and residue.

Futures exchange

Futures exchange

A futures exchange or futures market is a central financial exchange where people can trade standardized futures contracts defined by the exchange. Futures contracts are derivatives contracts to buy or sell specific quantities of a commodity or financial instrument at a specified price with delivery set at a specified time in the future. Futures exchanges provide physical or electronic trading venues, details of standardized contracts, market and price data, clearing houses, exchange self-regulations, margin mechanisms, settlement procedures, delivery times, delivery procedures and other services to foster trading in futures contracts. Futures exchanges can be organized as non-profit member-owned organizations or as for-profit organizations. Futures exchanges can be integrated under the same brand name or organization with other types of exchanges, such as stock markets, options markets, and bond markets. Non-profit member-owned futures exchanges benefit their members, who earn commissions and revenue acting as brokers or market makers. For-profit futures exchanges earn most of their revenue from trading and clearing fees.

Ford Thames 307E

Ford Thames 307E

The Thames 307E is a small panel van launched by Ford UK in June 1961 and based on the recently introduced Ford Anglia 105E. It replaced the Thames 300E and, like its predecessor it was marketed as the Thames 5 cwt or the Thames 7 cwt van. These names defined, in Imperial measurements, the recommended maximum load weights of the vehicles. Advertised load space was 73 cubic feet (2,100 L) including 12 cubic feet (340 L) beside the driver.

Canadian Military Pattern truck

Canadian Military Pattern truck

Canadian Military Pattern (CMP) trucks were mutually coherent ranges of military trucks, made in large numbers, in several classes and numerous versions, by Canada's branches of the U.S. 'Big Three' auto-makers during World War II, compliant to British Army specifications, primarily intended for use in the armies of the British Commonwealth allies, but also serving in other units of the British Empire.

Europe

In Europe outside British Isles, a centum or quintal was never defined in terms of British units. Instead, it was based on the kilogramme or former customary units. It is usually abbreviated q. It was 50 kg in Germany, 48.95 kg in France, 56 kg in Austria, etc. The unit was phased out or metricized after the introduction of the metric system in the 1790s, being occasionally retained in informal use up to mid-20th century.[11]

Metric system

Metric system

The metric system is a system of measurement that succeeded the decimalised system based on the metre that had been introduced in 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.
