PPM to mg/L Converter

1. What is a PPM to mg/L Converter?

Definition: This converter transforms parts per million (ppm) into milligrams per liter (mg/L) using solute density.

Purpose: It is used in chemistry and environmental science to determine concentration levels in solutions.

2. How Does the Converter Work?

Concentration in mg/L is calculated using:

\[ \text{mg/L} = \frac{\text{ppm} \times \text{Density (kg/m³)}}{1000} \]

Density conversions to kg/m³:

  • lb/ft³: × 16.0185
  • lb/gal: × 119.826
  • lb/in³: × 27679.9
  • g/mL: × 1000
  • g/L: × 1
  • g/cm³: × 1000
  • kg/L: × 1000
  • kg/m³: × 1
Other concentration units:
  • µg/L = mg/L × 1000
  • g/L = mg/L / 1000
  • kg/m³ = mg/L / 1000

Explanation: Density is converted to kg/m³, then multiplied by ppm and divided by 1000 to get mg/L. Other units are derived from mg/L.

3. Importance of Concentration Conversion

Details: Accurate conversion is critical for water quality analysis, chemical dosing, and environmental monitoring.

4. Using the Converter

Tips: Enter the ppm value and solute density (in units like lb/ft³, g/mL, etc.; >0). Results include mg/L, µg/L, g/L, and kg/m³.
