     subtype:  #bandwidth  a data transmission rate; the maximum amount of information (bits/second) that can be transmitted along a channel
     subtype:  #baud__baud_rate  (computer science) a data transmission rate (bits/second) for modems
  subtype:  #utility.system_of_measurement  (economics) a measure that is to be maximized in any situation involving choice
     subtype:  #marginal_utility  (economics) the amount that utility increases with an increase of one unit of an economic good or service
  subtype:  #Brix_scale  a system for measuring the concentration of sugar solutions
  subtype:  #circular_measure  measurement of angles in radians
