What TDS Calculator does
The Omni Calculator TDS Calculator determines the total dissolved solids (TDS) in water from either a full chemical analysis or electrical conductivity measurements. Users can input concentrations of specific ions such as chloride, sulfate, calcium, magnesium, and others, or simply enter the electrical conductivity (EC) value to receive an estimated TDS in milligrams per liter (mg/L). The tool also provides guidance on converting between EC and TDS, interpreting TDS levels, and classifying water quality. The result is a practical estimate of the concentration of all inorganic and organic compounds present in the water sample.
How to use the Omni Calculator TDS Calculator
- 1
Select the calculation method: chemistry analysis or electrical conductivity (EC).
- 2
Enter the concentration values for relevant ions (e.g., Calcium, Magnesium, Sodium, Chloride) or input the EC value in the designated field.
- 3
The calculator processes the inputs and displays the estimated total dissolved solids (TDS) in mg/L.
- 4
Review the additional information provided on EC-to-TDS conversion and water classification if needed.
- 5
Use the 'Share result' or 'Clear all changes' options to manage or export the output.
Best for
This option suits chemistry students, water quality enthusiasts, or anyone needing a quick estimate of TDS from ion concentrations or conductivity without performing manual calculations.
Limitations
- Results are estimates based on provided inputs and standard conversion factors.
- No unit switching available beyond the default mg/L output.
- The tool does not replace professional water testing laboratory analysis.
TDS Calculator FAQ
- Can I calculate TDS if I only know the electrical conductivity of my water sample?
- Yes, the calculator allows you to input the electrical conductivity (EC) value directly, and it will estimate the total dissolved solids (TDS) based on that measurement.
- What units does the TDS Calculator use for its output?
- The tool outputs total dissolved solids (TDS) in milligrams per liter (mg/L), which is equivalent to parts per million (ppm).
- Does the calculator provide information on how to interpret the TDS result?
- Yes, the tool includes sections on levels of TDS and water classification to help users understand what the calculated value means for water quality.
- Can I use this calculator for seawater or highly saline water?
- The calculator is designed for general water chemistry analysis; for highly saline samples like seawater, specialized formulas and conversion factors may be required for accurate results.
