Rack units are typically denoted without a space between the number of units and the 'U'. Thus, a 4U server enclosure (case) is seven inches (177.8 mm) high, or more practically, built to occupy a vertical space seven inches high, with sufficient clearance to allow movement of adjacent hardware.
Example: A yardarm is 6 inches long in 3/16" scale. Find its length in 1/8" scale. F = .67 (from table) D2 = 6" × .67 = 4.02 = 4" It is easier to make measurements in the metric system and then multiply them by the scale conversion factor. Scales are expressed in fractional inches, but fractions themselves are harder to work with than metric ...
A simple fraction (also known as a common fraction or vulgar fraction) [n 1] is a rational number written as a/b or , where a and b are both integers. [9] As with other fractions, the denominator (b) cannot be zero. Examples include 1 / 2 , − 8 / 5 , −8 / 5 , and 8 / −5 .
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.
The Q notation is a way to specify the parameters of a binary fixed point number format. For example, in Q notation, the number format denoted by Q8.8 means that the fixed point numbers in this format have 8 bits for the integer part and 8 bits for the fraction part.

There are anecdotal objections to the use of metric units in carpentry and the building trades, on the basis that it is easier to remember an integer number of inches plus a fraction, rather than a measurement in millimeters, [9] or that foot-inch measurements are more suitable when distances are frequently divided into halves, thirds, and ...
During the Korean and Vietnam Wars, there was limited use of the Lazy Dog bomb, a kinetic projectile shaped like a conventional bomb but only about 1 + 3 ⁄ 4 inches (44 mm) long and 1 ⁄ 2 inch (13 mm) in diameter. A piece of sheet metal was folded to make the fins and welded to the rear of the projectile.
