About This Tool
The tool provides a domain-focused conversion from TDS (mg/L) to EC (µS/cm) using a simple empirical model. It is designed for water quality professionals, environmental labs, and field technicians who need quick estimates for screening and reporting without performing complex laboratory analyses.
Conceptually, TDS reflects ionic content and EC measures ionic conductivity. The tool uses EC = TDS × 0.64 as the default mapping, reflecting common laboratory-derived relationships for many natural waters. Optional calibration may adjust the factor to reflect specific matrices; the factor is not fixed and may vary by water composition.
Core features include a single input field for TDS, immediate EC output, and a numeric result formatted to two decimals. It supports standard SI units, offers documentation of the underlying factor, and is suitable for rapid screening, field checks, or QA workflows. Primary benefits are speed, consistency, and traceability in reports.
How to Use
1. Provide inputs: Enter TDS value in mg/L.
2. The tool applies the default conversion factor (0.64) to estimate conductivity in µS/cm.
3. Read the computed EC value and note the two-decimal formatting.
4. If you know the matrix differs from standard waters, consider applying a different factor in advanced usage to reflect the composition.
5. Use the result for quick screening, documentation, and QA checks.
