TDS Calculation Formula:
| From: | To: |
The Electrical Conductivity to TDS conversion is a method to estimate Total Dissolved Solids (TDS) in water based on its electrical conductivity (EC) measurement. This conversion uses a standard factor to provide a quick estimation of dissolved solids content.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor of 0.64 is commonly used to estimate TDS from electrical conductivity measurements in many water quality applications.
Details: TDS measurement is crucial for assessing water quality, determining water purity for various applications, and monitoring the effectiveness of water treatment processes in both industrial and domestic settings.
Tips: Enter electrical conductivity value in μS/cm. The value must be valid (greater than 0). The calculator will provide the estimated TDS in parts per million (ppm).
Q1: Why use the 0.64 conversion factor?
A: The 0.64 factor is a widely accepted standard conversion that provides a good estimation of TDS from EC measurements for most natural waters.
Q2: What are typical TDS levels in drinking water?
A: TDS levels below 500 ppm are generally considered acceptable for drinking water, though ideal levels are typically between 50-150 ppm.
Q3: Can this conversion be used for all water types?
A: While the 0.64 factor works well for most natural waters, specific water compositions may require different conversion factors for optimal accuracy.
Q4: How does temperature affect EC measurements?
A: Electrical conductivity increases with temperature. Most modern EC meters automatically compensate for temperature variations to provide standardized readings.
Q5: What's the difference between TDS and EC?
A: EC measures water's ability to conduct electricity, which correlates with ion concentration, while TDS estimates the total weight of dissolved solids in water.
