The first commonly available increase in tape length resulted from a reduction in backing thickness from 1.5 to 1.0 mil (38 to 25 μm) resulting in a total thickness reduction from 42 to 35 μm (1.7 to 1.4 mils), which allowed 3,600 ft (1,100 m), 1,800 ft (550 m), and 900 ft (270 m) tapes to fit on ten-and-a-half-, seven-, and five-inch reels respectively.
The Broselow Tape, also called the Broselow pediatric emergency tape, is a color-coded length-based tape measure that is used throughout the world for pediatric emergencies. The Broselow Tape relates a child's height as measured by the tape to their weight to provide medical instructions including medication dosages, the size of the equipment ...
Brannock Device. The Brannock Device is a measuring instrument invented by Charles F. Brannock for measuring a person's shoe size. Brannock spent two years developing a simple means of measuring the length, width, and arch length of the human foot. He eventually improved on the wooden RITZ Stick, the industry standard of the day, [ 2] patenting ...
Long tapes, instead of being returned by a spring, are usually returned by hand crank. Because surveying was usually done in rods, surveyors used long tapes of 2 rods (10.1 m, 33 feet), and 4 rods (20.1 m, 66 feet). Surveyors also used 49 + 1 ⁄ 2 feet of a 50-foot tape for 3 rods and 99 feet of a 100-foot tape measure for 6 rods.
For a precision machinist level with 2 mm (0.079 in) divisions, when the vial is tilted one division, the level will change 0.04 mm (0.0016 in) one meter from the pivot point, referred to by machinists as 5 tenths per foot. This terminology is unique to machinists and indicates a length of 5 tenths of 1 thousandth of an inch. [3] [4]
From these figures for the size of a Biblical ell, that of the basic unit — the finger-breadth ( Etzba) — can be calculated to be either 2.1 or 2.2 cm (0.83 or 0.87 in); Rav Avraham Chaim Naeh approximates at 2 cm (0.79 in); Talmudic scholar Chazon Ish at 2.38 cm (0.94 in). The mile ( Mil) is thus about 963 or 1146 meters (3160 or 3760 ft ...
The joint European standard for size labelling of clothes, formally known as the EN 13402 Size designation of clothes, is a European standard for labelling clothes sizes. The standard is based on body dimensions measured in centimetres, and as such, and its aim is to make it easier for people to find clothes in sizes that fit them.
Schematic of a machine tap. Below is a comprehensive drill and tap size chart for all drills and taps, imperial and metric, up to 36.5 millimetres (1.44 in) in diameter.. In manufactured parts, holes with female screw threads are often needed; they accept male screws to facilitate the building and fastening of a finished assembly.
