Often, parts per million and milligrams per liter are used interchangeably. This is correct only if the density of the brine at standard conditions can be assumed to be 1 g/cc ( 1000 kg/m3, SG_w=1, 62.428 lbm/ft3) [1].
Nomenclature
= water salinity / solids concentration, ppm
= water salinity / solids concentration, mg/l
= weight percent solids, %
= water specific gravity, dimensionless
