Does Specific Gravity = Salinity Value?

[TygGer]

This is probably a stupid question...

I dont have the hydrometer on hand, but will the salinity always be equal to the SG? For instance, if the SG is 1.025, then the salinity will always equal 34ppt? Or can the SG be 1.025 and the salinity 25ppt?

Thanks

as far as i know the salinity will always equal the specific gravity but i could be wrong

yes, aresgod is correct

SG varies with temperature as well as salinity, and more than a bit too. Decent hydrometers are calibrated to a temperature, which nowadays is normally 25.

Essentially the same component.
