What Is This Tool?

This converter transforms concentration measurements from pounds per million gallons (US) into milligrams per liter (mg/L). It is especially useful in water and wastewater fields for assessing pollutant levels in solution.

How to Use This Tool?

  • Enter the concentration value in pound per million gallon (US)
  • Select pound/million gallon (US) as the input unit
  • Choose milligram per liter [mg/L] as the output unit
  • Click convert to get the equivalent concentration in mg/L

Key Features

  • Converts mass-per-volume units specific to water quality analysis
  • Uses the standard conversion factor from pound/million gallon (US) to mg/L
  • Browser-based and easy to use for environmental and laboratory applications

Examples

  • 5 pound/million gallon (US) converts to approximately 0.59913 mg/L
  • 10 pound/million gallon (US) converts to approximately 1.19826 mg/L

Common Use Cases

  • Setting permitted nutrient or contaminant levels in wastewater discharge permits
  • Calculating pollutant loadings by combining concentration and flow data
  • Reporting treatment plant performance and regulatory compliance for low-level constituents

Tips & Best Practices

  • Always confirm the solution density is close to typical water for accuracy
  • Use the conversion for dilute aqueous solutions commonly found in environmental testing
  • Verify unit consistency when integrating data from different measurement systems

Limitations

  • Conversion accuracy depends on standard water density; variations can affect results
  • Pound/million gallon (US) units are US customary volume based and may need adjustment internationally

Frequently Asked Questions

Why convert pound/million gallon (US) to milligram per liter?
This conversion helps translate pollutant concentrations into a more universally used laboratory unit, facilitating regulatory compliance and comparison.

Is the conversion accurate for all water types?
The conversion assumes dilute aqueous solutions with typical water density, so accuracy may decrease with different water conditions.

Can this unit be used outside the US?
Pound per million gallon (US) is specific to US volumes and might require adjustment for use in other countries.

Key Terminology

Pound/million gallon (US)
A concentration unit representing one avoirdupois pound of substance distributed in one million US gallons of water, used for very low pollutant levels.
Milligram per liter [mg/L]
A measure of concentration expressing milligrams of solute per liter of solution, commonly used in water quality testing.
Concentration
The amount of a substance contained in a given volume of solution, often expressed as mass per volume.
