    The Practical Salinity Scale (PSS-78). This is a dimensionless quantity for the measurement of sea water salinity. In principle, the unit of measurement associated to this quantity has no symbol. However Apache SIS uses the "psu" symbol for avoiding confusion with other dimensionless units.

    Salinity quantities should not be converted to quantities of other types. If nevertheless a conversion to Dimensionless is attempted, then Apache SIS implementation maps 1 psu to 1‰ for rough correspondence with legacy (before 1978) salinity measurements.

    Most quantity types are defined in the javax​.measure​.quantity. This Salinity type is an extension to the standard types.
