There’s also meq/L for alkalinity lolThere are two - SG for salinity and ppt for Alkalinity.
EDIT: ppm* not ppt

True and it would be correct as well, but it is not commonly used (AFAIK) by reefers as Randy's hint suggested.There’s also meq/L for alkalinity lol

Some great answers and rationale!
Consider also the difference between temp effects on a partly volume based measurement vs temp effects on a pure mass based measurement.
There’s another as well.
1. Nitrate at 8 ppm
2. The salinity at 35 ppt
3. pH at 8.1
4. Alkalinity at 7.4 dKH
Thank you for the detailed explanation Randy, I definitely learned a thing or two
I guess I leaned a bit too much towards the measurement methods at the end, but I was correct about the part-per-* units
I've read more about PSU (PSS-78) but one thing I couldn't understand is that wikipedia for some reason says it shouldn't be used as unit, which kinda left me baffled. Do you know what they mean by any chance? My first guess was about the fixed temperature but it doesn't add up. If anything, that's what makes it a more correct unit to describe measured salinity compared to most other units where you also need to specify the temp used to measure.
My second guess was because the name of the unit is already in use for a different kind of measurement, but they would simply name it differently if it was a problem in the first place.
Oh right, rereading it again I think you are correct.I think it just means you should say “the salinity is 35” and not “the salinity is 35 PSU”.
