Salinity/TDS Converter

Salinity/TDS Converter

Our Salinity/TDS Converter provides accurate conversions between various salinity and total dissolved solids units. Whether you're working with Practical Salinity Units (PSU), grams per kilogram (g/kg), milligrams per liter (mg/L), or other salinity measurements, this tool delivers precise results instantly.

Supported Unit Categories:

• Practical Salinity Units (PSU): Standard oceanographic salinity measurement
• Mass-based Units: Grams per kilogram (g/kg), parts per thousand (ppt)
• Concentration Units: Milligrams per liter (mg/L), parts per million (ppm)
• Conductivity Units: Siemens per meter (S/m), microsiemens per centimeter (μS/cm)

Salinity Measurement Systems:

• PSU (Practical Salinity Units): Based on electrical conductivity, used in oceanography
• g/kg (Grams per Kilogram): Mass ratio of dissolved salts to seawater
• mg/L (Milligrams per Liter): Mass concentration of dissolved solids
• ppt (Parts per Thousand): Traditional salinity measurement (‰)

Common Conversions:

• 35 PSU ≈ 35 g/kg ≈ 35,000 mg/L (typical ocean salinity)
• 0 PSU = 0 g/kg = 0 mg/L (freshwater)
• 1 PSU ≈ 1 g/kg ≈ 1,000 mg/L
• 1 g/kg = 1,000 mg/L (at 4°C, density ≈ 1 g/cm³)

How to Use:

1. Enter the salinity or TDS value you want to convert
2. Select the source unit from the "From" dropdown
3. Select the target unit from the "To" dropdown
4. View the converted result instantly
5. Use the swap button to quickly reverse the conversion

Applications:

This salinity/TDS converter is essential for oceanographers, marine biologists, environmental scientists, water quality professionals, aquarists, and anyone working with saline water or dissolved solids. It's particularly useful for research, monitoring, aquaculture, and educational purposes.
