Examples: Colour (value: green, blue), transparency, length (value: long, short; \\(2\\ \\rm{m}\\), \\(5\\ \\rm{m}\\)), amount-of-substance (value: \\(\\pu{2 mol}\\), \\(\\pu{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\\ ^{\\,\\unicode{x26ac}}\\rm{C}\\) (i.e. \\(10\\ ^{\\,\\unicode{x26ac}}\\rm{C}\\) more than an arbitrary zero)] or ratio scales (length \\(2\\ \\rm{m}\\) or \\(5\\ \\rm{m}\\)).","links":[{"term":"kind-of-quantity","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/K03393"}],"sources":["PAC, 1995, 67, 1563.
