Den is a direct measure of linear density. [5] dtex (deci-tex): Grams per 10,000 metres of yarn. Dtex is a direct measure of linear density. [5] gr/yard: Grains per yard of yarn. Gr/yard is a direct measure of linear density, but is rarely used in the modern textile industry. ECC or NeC or Ne (English Cotton Count): The number of 840 yd lengths ...
In 1866, the U.S. Congress passed a law that allowed, but did not require, the use of the metric system in trade and commerce. Included in the law was a table of conversion factors between the customary (i.e. English-derived) and metric units, among them a definition of the meter in terms of the yard, and the kilogram in terms of the pound.
The first group of metric units are those that are at present defined as units within the International System of Units (SI). In its most restrictive interpretation, this is what may be meant when the term metric unit is used. The unit one (1) is the unit of a quantity of dimension one. It is the neutral element of any system of units. [2]
Traditional Burmese units of measurement are used in Burma, with partial transition to the metric system. U.S. units are used in limited contexts in Canada due to the large volume of trade with the U.S. There is also considerable use of imperial weights and measures, despite de jure Canadian conversion to metric.
For example, to compare 32 metres with 35 yards, use 1 yard = 0.9144 m to convert 35 yards to 32.004 m. A related principle is that any physical law that accurately describes the real world must be independent of the units used to measure the physical variables. [ 7 ]
New conversion factors for the rod and furlong as 16.5 international feet and 660 international feet respectively have been published by NIST. [71] However, it is not clear if a "survey yard" actually exists. [72] If it did, its hypothetical values would be as follows: 3937 survey yards = 3600 meters [69] 1 survey yard ≈ 0.914 401 83 meters [69]

The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
