Why does this matter? In reference to electronic equipment racks, such as those that are 19 or 23 inches wide, the term 1U refers to one rack unit of height. 1.75 inches (44.45 mm) of rack height is equal to 1 U. As a result, the height of a 2U rack mount would be 2 x 1.75", or 3.5 inches.
A rack was originally a stack of $100 bills totaling $10,000, but because the word is frequently used in songs like "Racks on Racks" and "Rack City," most people now refer to $1,000 as a rack.
A rack (or racks) is a thousand-dollar sum of money. A rack typically refers to merely $1,000 because not many individuals have numerous $100 bills stacked up in stacks of $10,000 to sing about.

a 4u rack Typically, this rack measures 19 inches. It features four rack units, as the name would imply, all spaced equally apart.
One rack unit (1U) is comparable to three rack hole spaces in height and measures 1.75′′ (44.45 mm) in the vertical direction.
19 inches is the most typical standard rack width. The mounting width of the majority of rack-mounted equipment, particularly servers, is 19 inches, measured from one hole to the next. Thus, for this technology to work, the rack needs to be 19 inches broad. The outer width of many racks today is 24 inches.
What does one rack unit (1U) mean? The usual size for servers and other network hardware deployed in 19-inch server racks is one rack unit, or U. These racks provide space for items that are 19" broad (482.6 mm) and vary in height, which is indicated in rack units. 1.75" or 44.45 mm is 1U.
A piece of computer or network equipment's height that is intended to fit into a typical 19- or 23-inch rack is measured in "U" or "rack units."
