1. What is TDS to Conductivity Conversion?

Total Dissolved Solids (TDS) and conductivity are related water quality parameters. Conductivity measures water's ability to conduct electricity, while TDS estimates the total dissolved solids. The conversion between them uses a factor typically between 0.5 and 0.7.

2. How Does the Calculator Work?

The calculator uses the TDS to Conductivity formula:

Where:

• \( TDS \) — Total Dissolved Solids in parts per million (ppm)
• \( Factor \) — Conversion factor (typically 0.55-0.75, most commonly 0.67)

Explanation: The factor accounts for the relationship between the ionic content (which affects conductivity) and the total dissolved solids in water.

3. Importance of Conductivity Measurement

Details: Conductivity is a key water quality parameter that indicates the presence of dissolved ions. It's used in water treatment, environmental monitoring, and industrial processes.

4. Using the Calculator

Tips: Enter TDS value in ppm and select an appropriate factor (default is 0.67). The factor varies based on water composition - use 0.5 for NaCl solutions, 0.55-0.75 for natural waters.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor not constant?
A: Different dissolved ions have different conductivities. The factor varies based on the composition of dissolved solids.

Q2: What's the most common conversion factor?
A: 0.67 is commonly used for natural waters, but the exact factor should be determined experimentally for specific water sources.

Q3: Can I use this for seawater?
A: No, seawater has a different ionic composition requiring specialized conversion methods.

Q4: How accurate is this conversion?
A: It provides a reasonable estimate but for precise measurements, direct conductivity measurement is recommended.

Q5: What units are used?
A: TDS is in ppm (parts per million) and conductivity is in μS/cm (microsiemens per centimeter).
