  ns0:discussion "As for SI and IUPAC conventions, OPB distinguishes:   1) physical dimensions as orthogonal aspects of measureable physical entities (e.g., mass, temperature),   vs.   2) the physical units by which such aspects are conventionally quantified (e.g., kilogram, degree Celsius)  _______________________________________  OPB:Physical dimension subclasses are a set of base dimensions as identified by either:  IUPAC (International Union of Pure and Applied Chemistry) in their Green Book [1] as summarized in: Concise Summary of  Quantities, Units and Symbols in Physical Chemistry [2]. IUPAC base quantities are:   length, time, mass, electric current, thermodynamic temperature, luminosity, amount of substance.  UCUM (Unified Code for Units of Measure [3]) defines an alternative (but ultimately, equivalent) set of base quantity kinds [4] as:  length, time, mass, charge, temperature, luminous intensity, angle.  In either system, a coherent set of working property dimensions can be derived for for other physical properties as products of base dimensions raised to integer (both positive and negative) powers (e.g., velocity = length•time-1, pressure = force•length-2, volume = length+3).
