converting from salinity from SG?

[aggiereefer]

anyone know how to convert specific gravity readings into PPM or PPT numbers? I can only find literature on the internet that describes the salinity of water in PPM and not SG.

Is that what you're looking for?

Taken straight from my hydrometer, a SG of 1.020 is ~27ppt and 1..025 is ~34.

 

Incase you want a quick range to check against rather then entering numers to that calc.

i was doin research online and all I could find was the salinity of the local bays in PPT numbers. I was curious about keeping a few local fish in a seperate tank. Thanks for the help.

if it helps any, the ocean is at approximately 35 ppt.

 

i think refractometers will give you both specific gravity and salinity.
