RU Calc is a small utility to convert rack units to inch or cm and vice versa.
The inch/cm switch on the RU to inch/cm view recalculates the inch/cm value for a given RU number on the fly and sets the switch on the inch/cm to RU to the same unit (inch or cm). Results are recalculated too.
Cool app for a fast and easy calculation if you have a given number of RU´s or if you have to know how many RU´s can be used for a given space.
