    In the tables of quantities and their units, the ISO 31-8 standard shows symbols for substances as subscripts (e.g., c B, w B, p B). It also notes that it is generally advisable to put symbols for substances and their states in parentheses on the same line, as in c (H 2 SO 4 ).

  7. List of physical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_physical_constants

    The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured. Many of these are redundant, in the sense that they obey a known relationship with other physical ...
