  a qudt:QuantityKind ;
  dcterms:description """In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an
    associated physical dimension. It is thus a "pure" number, and as such always has a dimension of 1. Dimensionless quantities
    are widely used in mathematics, physics, engineering, economics, and in everyday life (such as in counting). Numerous
    well-known quantities, such as $\\pi$, $\\epsilon$, and $\\psi$, are dimensionless. By contrast, non-dimensionless quantities
    are measured in units of length, area, time, etc. Dimensionless quantities are often defined as products or ratios of
    quantities that are not dimensionless, but whose dimensions cancel out when their powers are multiplied.
