About the Salinity Converter
Convert salinity between grams per liter (g/L), parts per thousand (ppt), practical salinity units (psu), and percent (%). Enter a value above, choose the source and target units, then click Convert. All calculations run locally in your browser for speed and privacy.
Assumptions and notes
- For typical dilute aqueous solutions, 1 ppt ≈ 1 g/L and 1 psu ≈ 1 ppt.
- Percent (% w/v) is approximated as 1% ≈ 10 g/L assuming solution density near 1 g/mL.
- For high precision oceanographic work, density and temperature effects may be considered; this tool favors practical everyday use.
How to use
