What is this calculator used for?

The TDS (Total Dissolved Solids) Calculator is used to determine the concentration of dissolved substances in water, expressed in ppm (parts per million). It is useful in water quality testing, aquarium maintenance, and laboratory analysis.

How to use this calculator?

• Enter the volume of water in liters.
• Enter the mass of dissolved solids in milligrams (mg).
• The calculator will automatically display the TDS in ppm.

Formula:

TDS (ppm) = (Mass of dissolved solids in mg / Volume of water in L)

Example:

If you have 500 mg of dissolved solids in 2 liters of water:

TDS = 500 / 2 = 250 ppm
