    Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.

  5. dBFS - Wikipedia

    en.wikipedia.org/wiki/DBFS

    Decibels relative to full scale (dBFS or dB FS) is a unit of measurement for amplitude levels in digital systems, such as pulse-code modulation (PCM), which have a defined maximum peak level. The unit is similar to the units dBov and decibels relative to overload (dBO). [1] The level of 0 dBFS is assigned to the maximum possible digital level. [2]

    Granite has a measured viscosity at standard temperature and pressure of about 4.5×10 19 Pa·s [1] so it should be considered a rheid. Similarly halite , the mineral form of table salt , is a geological material that behaves as a rheid over relatively short time-periods.
