___________________
o The
height of a rack in inches depends on the number of U units
it has. Each U (rack unit) equals 1.75 inches.
Example:
§ 6U
rack: 6×1.75=10.56×1.75=10.5 inches.
§ 12U
rack: 12×1.75=2112×1.75=21 inches.
§ 42U
rack: 42×1.75=73.542×1.75=73.5 inches.
So, for any rack height,
multiply the U number by 1.75 to get the
height in inches!
