## USAGE:

    SonCl = gsw_SonCl

## DESCRIPTION:

    The ratio of Practical Salinity, SP, to Chlorinity, 1.80655 kg/g for
    Reference Seawater (Millero et al., 2008).  This is the ratio that was
    used by the JPOTS committee in their construction of the 1978 Practical
    Salinity Scale (PSS-78) to convert between the laboratory measurements
    of seawater samples (which were measured in Chlorinity) to Practical
    Salinity.

## OUTPUT:

    SonCl  =  SP to Chlorinity ratio                           [ (g/kg)^-1 ]

## EXAMPLE:

    SonCl = gsw_SonCl

    SonCl =

      1.80655
