kind-of-property

An attribute of phenomena, bodies or substances that may be distinguished qualitatively. Examples: Colour (value: green, blue), transparency, length (value: long, short; $2 m$ , $5 m$ ), amount-of-substance (value: $2 mol$ , $5 mol$ ). Kind-of-property includes the concept kind-of-quantity. All kinds-of-property may be related to nominal (e.g. green, blue) and ordinal scales (e.g. small, large), but kinds-of-quantity are generally related to difference [e.g. $10 °C$ (i.e. $10 °C$ more than an arbitrary zero)] or ratio scales (length $2 m$ or $5 m$ ).
