Staples are often described as X/Y (e.g. 24/6 or 26/6), where the first number X is the gauge of the wire , and the second number Y is the length of the shank (leg) in millimeters. Some exceptions to this rule include staple sizes like No. 10. Common sizes for the home and office include: 26/6, 24/6, 24/8, 13/6, 13/8 and No. 10 for mini staplers.
The momme is based on the standard width of silk of 45 inches (1.1 m) wide (though silk is regularly produced in 55-inch (1.4 m) widths and uncommonly in larger widths). The usual range of momme weight for different weaves of silk are: Habutai—5 to 16 mm; Chiffon—6 to 8 mm (can be made in double thickness, i.e. 12 to 16 mm)
The staple length of the wool is the length of the staple, and highly correlated with mean fibre length in the top (hauteur). Staple length generally determines the end use of wool, that is, whether it will be used in weaving or knitting. The longer wools, generally around 51 mm and longer and called combing types, are processed to worsted yarn
This device weighed over two and a half pounds and loaded a single 1 ⁄ 2-inch-wide (13 mm) wire staple, which it could drive through several sheets of paper. The first published use of the word "stapler" to indicate a machine for fastening papers with a thin metal wire was in an advertisement in the American Munsey's Magazine in 1901.
The standard railway track gauge, fixed at 4 feet 8 + 1 ⁄ 2 inches (1,435.1 mm) in 1845, [94] was redefined as 1,435 mm [95] – a nominal decrease of 0.1 mm but within the engineering tolerances. Motorway marker posts used by road maintenance teams and emergency services demarcate locations in multiples of 100 m. [ 96 ]
The millimetre (SI symbol: mm) is a unit of length in the metric system equal to 10 −3 metres ( 1 / 1 000 m = 0.001 m). To help compare different orders of magnitude, this section lists lengths between 10 −3 m and 10 −2 m (1 mm and 1 cm). 1.0 mm – 1/1,000 of a meter; 1.0 mm – 0.03937 inches or 5/127 (exactly)
Centimeters (cm) are avoided as they cause confusion when reading plans. For example, the length two and a half meters is usually recorded as 2500 mm or 2.5 m; it would be considered non-standard to record this length as 250 cm. [ 12 ] [ 13 ]
A standard metric (concrete) block is 190 mm wide, 390 mm long, and 190 mm high, which allows for 10 mm mortar joints in between bricks, giving a standard unit size of 200 mm square by 400 mm long. [3] A standard metric brick is 90 by 57 by 190 mm; with 10 mm of mortar, that produces a standard unit of 100 mm x 200 mm. [3]
