Reef Salinity Calculator

Convert PPT, specific gravity, conductivity, and density with temperature compensation

Our advanced salinity calculator converts between all common reef aquarium salinity measurements including PPT/PSU, specific gravity, conductivity (mS/cm), and density. Features temperature compensation for maximum accuracy, essential for maintaining optimal reef tank salinity levels. Perfect for reef keepers using different testing equipment or comparing measurements from various sources.

Measurement Units

Temperature

Enter the temperature of the measured salt water.

Salinity Value

Select and enter the salinity value you want to convert.

Converted Values

The converted salinity values.

Enter Values to Calculate

Input temperature and salinity values to see results

Note: All conversions are temperature-compensated for accuracy. Ideal reef salinity is typically 35 PPT (1.026 S.G.).

Eliminate confusion between different salinity measurements and ensure your reef tank maintains the perfect 35 PPT salinity level for optimal coral and fish health.

Enter your salinity reading in any unit along with water temperature. Our calculator instantly converts to all other salinity units with temperature compensation for laboratory-grade accuracy.
