The proper weight for a cat can vary widely, depending on the cat's build. My four normal-weight cats range from 6.5 pounds up to 14 pounds. Some large-breed cats such as Maine Coons can weigh 24 pounds and be normal, though most domestic cats would be obese at that weight. http://www.cvm.tamu.edu/clinicalnutritio...
A Rack Unit or Rack U is an EIA standard allowance unit for measuring rack mount equipment. One Rack Unit is equal to 1.75 in height. To calculate internal useable space of a rack enclosure, simply multiply the total amount of Rack Units by 1.75. For example, a44U rack enclosure would have 77 of internal usable space (44 x 1.75).

Almost all data centers have standardized on 42U racks. The EIA (Electronic Industries Alliance) standard server rack is a 19 inch wide rack enclosure with rack mount rails which are 17 3/4â³ (450.85 mm) apart and whose height is measured in 1.75â³ (44.45 mm) unit increments.A 42U rack would have an internal rack unit height dimension of 73.5 inches (1.8669 m).he EIA (Electronic Industries Alliance) standard server rack is a 19 inch wide rack enclosure with rack mount rails which are 17 3/4â³ (450.85 mm) apart and whose height is measured in 1.75â³ (44.45 mm) unit increments.
