What Is EC and PPM?

EC (Electrical Conductivity) measures the ability of a solution to conduct electricity, commonly used to estimate nutrient levels in hydroponics, agriculture, and water quality testing. It is expressed in microsiemens per centimeter (µS/cm) or millisiemens per centimeter (mS/cm).

PPM (Parts Per Million) quantifies the concentration of dissolved solids in water or solution, indicating the total dissolved solids (TDS). It represents the mass of solute per million units of solution.

Why Convert EC to PPM?

🌱 Nutrient Management: Growers monitor EC to manage fertilizer and nutrient concentrations but often need PPM for precise measurements.
💧 Water Quality: Water treatment professionals use PPM to evaluate contamination levels.
📊 Standardization: Conversion allows compatibility between different measurement standards and devices.

How to Convert EC to PPM?

The conversion from EC to PPM depends on the conversion factor, which varies by solution type but commonly falls between 500 and 700.

$Factor\text{PPM} = \text{EC} \times \text{Conversion Factor}$

Typical conversion factors:
- 500: Used by many TDS meters (NaCl scale)
- 640: Average conversion factor for general solutions
- 700: For solutions rich in minerals like calcium and magnesium

Step-by-Step Conversion Example

If your EC reading is 1.2 mS/cm, using a conversion factor of 640:

$ppm\text{PPM} = 1.2 \times 640 = 768 \, \text{ppm}$

This means the total dissolved solids concentration is approximately 768 ppm.
