Conductivity to TDS Calculator

Converting electrical conductivity to Total Dissolved Solids (TDS) is a common practice in water quality testing. This conversion helps in assessing the amount of dissolved solids in water, which can be crucial for applications ranging from agricultural irrigation to industrial processes.

Historical Background

The relationship between electrical conductivity and TDS stems from the principle that dissolved ions in water enhance its ability to conduct electricity. This correlation has been utilized in water quality assessments for decades, providing a quick and indirect measure of water's solute content.

Calculation Formula

To convert electrical conductivity (C) to TDS, the formula is as follows:

\[ \text{TDS} = C \times 0.64 \]

where:

• \(\text{TDS}\) is the Total Dissolved Solids in parts per million (ppm),
• \(C\) is the electrical conductivity in microsiemens per centimeter (µS/cm).

Example Calculation

For a water sample with an electrical conductivity of 1500 µS/cm, the TDS is calculated as:

\[ \text{TDS} = 1500 \times 0.64 = 960 \text{ ppm} \]

Importance and Usage Scenarios

Monitoring TDS is essential in many sectors, including environmental monitoring, aquaculture, hydroponics, and water treatment facilities. High TDS levels can affect water taste, lead to scaling in pipes and appliances, and impact aquatic life.

Common FAQs

1. What is electrical conductivity?

   • Electrical conductivity is a measure of water's ability to pass an electrical current, influenced by the presence of dissolved ions.

2. Why is TDS important?

   • TDS levels indicate the quality of water. High TDS can be a sign of harmful contamination, while very low TDS may indicate a lack of essential minerals.

3. Can TDS affect human health?

   • Drinking water with very high TDS levels can lead to health issues due to the presence of toxic ions, whereas low TDS water might lack beneficial minerals.
