Unified atomic mass unit Unified atomic mass unit. The unified atomic mass unit (symbol: u) or dalton (symbol: Da) is a standard unit of mass that quantifies mass on an atomic or molecular scale (atomic mass). One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol. It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest, and has a value of 1.660 539 040 (20) × 10 −27 kg, or approximately 1.66 yoctograms.

- When used to describe the rack enclosure itself, the term half-rack typically means a rack enclosure that is half the height (22U tall). A front panel or filler panel in a rack is not an exact multiple of 1.75 inches (44.45 mm).To allow space between adjacent rack-mounted components, a panel is 1⁄32 inch (0.031 inch or 0.79 mm) less in height than the full number of rack units would imply. Thus, a 1U front panel would be 1.719 inches (43.66 mm) high.he 23 racks are from the Western Electric 23-inch standard, with holes on 1-inch (25.4 mm) centers; it is still used in legacy ILEC / CLEC facilities.
