Practical salinity units to grams per liter
Type a value in PSU to get it in g/L instantly.
35g/L
That's about the same as the open ocean. Every liter holds about 35 g of dissolved salt.
What it means
How salty is that?
Specific gravity depends on temperature. Aquarium hydrometers are usually calibrated at 25 °C, and a reading taken cold will be wrong.
The math
How to convert PSU to g/L
To convert practical salinity units to grams per liter, multiply by 1.
Example: 35 PSU × 1 = 35 g/L.
In the other direction, 1 g/L = 1 PSU.
