Hi All,

I have a question. Can anyone explain to me what 34 ppt translates to in gravity for salt water?

This was translated from a French website regarding breeding Amano Shrimp. I understand most salt water is at 1.023 specific gravity. But I am not familiar with the 34 ppt. Any information you could provide would be appreciated.

P.S. I would post a link to the website, however it seems to be down at the time. Thanks.
 
I'm guessing it's parts per trillion.

One part per trillion (ppt): Denotes one part per 1,000,000,000,000 parts, one part in 1012, and a value of 1 × 10–12. This is equivalent to 1 drop of water diluted into 20, two-meter-deep Olympic-size swimming pools (50,000 m³), or one second of time in approximately 31,700 years.

:eek: Blimey!!!!!!
 
You also need the temperature at a given salinity to get the correct specific gravity, since it greatly affects the reading.

DOH! I guess that does start with a "T". :rofl: My bad...
