Length. For measuring length, the U.S. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. From 1893, the foot was legally defined as exactly 1200⁄3937 m (approximately 0.304 8006 m). [13] Since July 1, 1959, the units of length have been defined on the basis of 1 yd = 0 ...
Unified Thread Standard. The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries.
PostScript is a page description language run in an interpreter to generate an image. [6] It can handle graphics and has standard features of programming languages such as branching and looping. [6] PDF is a subset of PostScript, simplified to remove such control flow features, while graphics commands remain. [6]
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.
ISO / IEC 7810 Identification cards — Physical characteristics is an international standard that defines the physical characteristics for identification cards. [1] The characteristics specified include: Physical dimensions. Resistance to bending, chemicals, temperature, and humidity. Toxicity.
These are large flags, usually 36 by 45 inches (91 cm × 114 cm), and mounted on a half pike which is 8 feet 7 + 1 ⁄ 2 inches (2.629 m) long; the king's or queen's colour (state or president's colour if the country is a republic) is usually a version of the country's national flag, often trimmed with gold fabric, and with the regiment's ...
Horizontal pitch (HP) is a unit of length defined by the Eurocard printed circuit board standard used to measure the horizontal width of rack mounted electronic equipment, similar to the rack unit (U) used to measure vertical heights of rack mounted equipment. One HP is 0.2 inches (1/5") or 5.08 millimetres wide.
The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the abbreviation NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizes. Because of the pipe wall thickness of Schedule pipe, the actual diameter of the NPT threads is larger than the Nominal ...
