Keel (unit)
Keel was a unit used to measure coal in the northeast of England, being the quantity of coal carried by a keelboat on the Tyne and Wear rivers. In 1750 it was said to be equal to 8 Newcastle chaldrons (waggons), a measure of volume, or a weight of 21.2 long tons or 424 cwt (21.54 metric tons).Shorter Oxford English Dictionary (3rd ed.)

Chaldron
A chaldron (also chauldron or chalder) was an English measure of dry volume, mostly used for coal; the word itself is an obsolete spelling of cauldron. It was used from the 13th century onwards, nominally until 1963, when it was abolished by the Weights and Measures Act 1963, but in practice until the end of 1835, when the Weights and Measures Act of that year specified that thenceforth coal could only be sold by weight. Coal The chaldron was used as the measure for coal from the 13th century, measuring by volume being much more practical than weighing low-value, high-bulk commodities like coal. It was not standardized, and there were many different regional chaldrons, the two most important being the Newcastle and London chaldrons. The Newcastle chaldron was used to measure all coal shipped from Northumberland and Durham, and the London chaldron became the standard measure for coal in the east and south of England. Many attempts have been made to calculate the weight of a Newc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keelmen
The Keelmen of Tyne and Wear were a group of men who worked on the keels, large boats that carried the coal from the banks of both rivers to the waiting collier ships. Because of the shallowness of both rivers, it was difficult for ships of any significant draught to move up river and load with coal from the place where the coal reached the riverside. Thus the need for shallow-draught keels to transport the coal to the waiting ships. The keelmen formed a close-knit and colourful community on both rivers until their eventual demise late in the nineteenth century. Beginnings of the coal trade Coal began to be exported from the River Tyne from the mid-thirteenth century onwards. The first recorded shipment of coal from the River Wear was in 1396. The pits from which coal was then exported were near the riverside so that as little effort as possible was required to load it. The coal was carried to London and elsewhere in colliers; small wooden sailing ships that sailed down the eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Units Of 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 less t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
