U Calculator



The "U", or "Rack Unit", was created by the Electronic Industries Association (EIA). The EIA standard was created for cabinets, racks and panels, as well as other associated equipment. It sets a standard for system spacing, mounting, bezel clearance, as well as placement of the mounting holes in the mounting flange.

Please use the Calculator below to convert between "U's" and inches. (This does not include the space at th top or bottom of the rack)
