Given the linear density and weight the yarn length can be calculated; for example: l/m = 1693 × l m /Nec × m/kg, where l/m is the yarn length in metres, l m /Nec is the English cotton count and m/kg is the yarn weight in kilograms. The following length units are defined. Bundle: usually 10 lb (4.5 kg)
A way of determining the weight of an unknown yarn is to use the wrapping method. This method is also used to calculate the amount of yarn needed for a project. By this method it is possible to check an unknown weight of yarn with a regular pencil and ruler [3] without unwinding the yarn. Simply slip the pencil under approximately an inch of ...
A hank of wool is 560 yards long (560 yd/lb = 1.129 km/kg). In theory a pound of 62s wool could produce 34720 yards of yarn. [1] As it is now a relatively simple matter to measure the average fibre diameter and distribution, spinning count is being replaced with the specification of average fibre diameter in micrometers and fiber distribution ...
Cotton Counts: Refers to the thickness of the cotton yarn where 840 yards of yarns weighs 1 pound (0.45 kg). 10-count cotton means that 8,400 yards (7,700 m) of yarn weighs 1 pound (0.45 kg). This is coarser than 40-count cotton where 40x840 yards are needed.
Although different cotton-growing countries have their bale standards, for example, In the United States, cotton is usually measured at approximately 0.48 cubic meters (17 cu ft) and weighs 226.8 kilograms (500 pounds). [6] In India, the standard bale size is 170 kg. [7] [8] [9] [10]
Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.
This is done by assigning a standard weight to each commodity that is to be measured in bushels. These bushels depend on the commodities being measured, and on the moisture content of the commodity. Some of the more common ones are: Oats: US: 32 lb [7] (14.5150 kg) Canada: 34 lb [8] (15.4221 kg) UK: 38 lb [9] (17.2365 kg) Barley: 48 lb [7] (21. ...
