A 1U server rack measures exactly 1. 45 mm) in height and fits standard 19-inch racks. For example, a typical full-size rack cage is 42U high, while equipment is typically 1U, 2U, 3U, or 4U high. The rack unit size is based on a standard rack specification as defined in EIA -310. The Eurocard specifies a standard rack unit as the unit of height; it also defines a similar unit. U (rack unit, RU) is a unit of equipment height in a 19" rack. Important: U describes height only, but a server's real "capabilities" are also determined by chassis depth, internal layout, airflow, rails, power, and expansion (PCIe/risers, NVMe. Originally defined by the EIA-310 standard, the rack specifies a front panel width of 19 inches (482. 6 mm), allowing different hardware from various manufacturers to fit in the same enclosure. The unit calculator below can convert rack U's into cm, inches and feet. You'll get the precise, standardized dimensions of a 1U server rack unit — including height (1. 45 mm), width (19″ / 48.
