Average salinity of sea water is 35ppt (34 to 36ppt), specific gravity is measured in sg (1.025sg). The hydrometer measures specific gravity while refractometer measures salinity. The 2 units of measurements are used interchangeably in the hobby, just a heads up.

Btw, sorry onizuka, I accidentally down your rep for one one the replies above when I meant to plus 1. I can't change it back so I added a point to your next reply :(

bro didn't see the minus therefore think it's admended, thanks !

never regret getting one as it's a sense of assurance hehe
