Chiffon—6 to 8 mm (can be made in double thickness, i.e. 12 to 16 mm) Crepe de Chine—12 to 16 mm; Gauze—3 to 5 mm; Raw silk—35 to 40 mm (heavier silks appear more "wooly") Organza—4 to 6 mm; Charmeuse—12 to 30 mm; The higher the weight in mommes, the more durable the weave and the more suitable it is for heavy-duty use.
The thickness of items such as paper, film, foil, wires, paint coatings, latex gloves, plastic sheeting, and fibers For example, most plastic ID cards are about 30 thou (0.76 mm) in thickness. Card stock thickness in the United States, where mils are also called points. [2] Gauge (diameter) of strings in stringed instruments [3] [4]
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
The area density (also known as areal density, surface density, superficial density, areic density, mass thickness, column density, or density thickness) of a two-dimensional object is calculated as the mass per unit area. The SI derived unit is the "kilogram per square metre" (kg·m −2).
Upon combining the resistivity with the thickness, the resistance can then be written as = =, where is the sheet resistance. If the film thickness is known, the bulk resistivity ρ {\displaystyle \rho } (in Ω ·m) can be calculated by multiplying the sheet resistance by the film thickness in m: ρ = R s ⋅ t . {\displaystyle \rho =R_{s}\cdot t.}
The number of wraps will act as a gauge to assess the thickness of unmarked yarn; for example 12 wraps per inch is 12 WPI, and is used to calculate how much yarn is required for various articles, [3] so that 12 is equivalent to 8 ply (worsted weight, medium weight) yarn.
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 board that is one foot (30.5 cm) in length, one foot (30.5 cm) in width, and one inch (2.54 cm) in thickness, or exactly 2.359 737 216 liters.
This was an official unit of measurement in South Africa until the 1970s, and was defined in November 2007 by the South African Law Society as having a conversion factor of 1 morgen = 0.856 532 hectares. [27] This unit of measure was also used in the Dutch colonial province of New Netherland (later New York and parts of New England). [28] [29]
