I am comparing my salinity data which I collected with a Refractometer that reads in parts per thousand (PPT) with recorded data collected in mg/L of chloride concentration - not TOTAL salts but just the chloride ion!

How do I compare my ppt of salinity data with recorded data when I am just given the mg/L of the chloride ion?? Help. I am not a chemistry person, I am just trying to analyze collected data. Many thanks.
