This smaller form factor is similar to that used in an HDD by Rodime in 1983, which was the same size as the "half height" 3 + 1 ⁄ 2 in (89 mm) FDD, i.e., 1.63 inches (41 mm) high. Today, the 1-inch high ("one-third height", "slimline", or "low-profile") version of this form factor is the most popular form used in most desktops and data centers .
Photo: 2.5 mm mono (TS), 3.5 mm mono and stereo (TRS), and 1 ⁄ 4 inch (6.4 mm) stereo (TRS) phone connectors The most common microphone connector in consumer use is the venerable phone connector, in 1 ⁄ 4 inch (6.4 mm), 3.5 mm, and 2.5 mm sizes, and in both mono and stereo configurations.
The 2.5 mm or sub-miniature sizes were similarly popularized on small portable electronics. They often appeared next to a 3.5 mm microphone jack for a remote control on-off switch on early portable tape recorders; the microphone provided with such machines had the on-off switch and used a two-pronged connector with both the 3.5 and 2.5 mm plugs.
Floppy disk size is often referred to in inches, even in countries using metric and though the size is defined in metric. The ANSI specification of 3½-inch disks is entitled in part "90 mm (3.5-inch)" though 90 mm is closer to 3.54 inches. [53] Formatted capacities are generally set in terms of kilobytes and megabytes.
The difference between those widths and the name of the bay size is because it is named after the size of floppy that would fit in those drives, a 5.25-inch-wide square. Half-height drive bays are 1 + 5 ⁄ 8 inches (41.3 mm) high by 5 + 3 ⁄ 4 inches (146.1 mm) wide, and are the standard housing for CD and DVD drives in modern computers. They ...
After the two common 5.5 mm OD (Outer Diameter) plugs, the next-most common size is 3.5 mm OD with a 1.3 mm ID (Inner Diameter), usually about 9.5 mm in length, although both longer and shorter versions also exist. These 3.5 mm OD plugs are normally used for lower voltages and currents.
Sizes are often expressed as a fraction of an inch, with a one in the numerator, and a decimal number in the denominator. For example, 1/2.5 converts to 2/5 as a simple fraction, or 0.4 as a decimal number. This "inch" system gives a result approximately 1.5 times the length of the diagonal of the sensor.
Lego trains use a fixed nominal gauge of 37.5 mm (1 + 15 ⁄ 32 in), based on 5-stud track centerlines gauge. [5] [6] [7] The 37.5 mm length is not derived by a certain scale ratio. While HO scale is a 1:87 scale (3.5 mm to 1 foot), resulting in a 16.5 mm (0.65 in) gauge from real life prototype 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge ...
