What Is This Tool?
This tool converts concentrations from pound per US gallon (lb/gal), a unit expressing mass per volume for solutions or liquids, to pound per million US gallons (lb/Mgal), a unit widely used for low pollutant concentration measurements in water and wastewater applications.

Tips & Best Practices
-
Ensure input values represent uniform mass distribution for accurate conversion
-
Use this converter primarily for dilute aqueous solutions or wastewater concentrations
-
Cross-check units carefully when working across industrial and environmental contexts
-
Combine concentration conversions with flow measurements for pollutant load calculations
Limitations
-
Assumes uniform distribution of mass within the specified volumes
-
Most applicable for dilute aqueous or wastewater solutions
-
Be cautious of scale differences between units when interpreting results
-
Potential for unit misinterpretation across industrial and environmental applications
Frequently Asked Questions
-
What does pound per gallon (US) measure?
-
It represents the mass in avoirdupois pounds contained in one US liquid gallon of solution, used for concentrations or densities of liquids.
-
Why convert pound/gallon (US) to pound/million gallon (US)?
-
To express concentrations at very different scales, especially low pollutant levels in large water volumes common in environmental and wastewater contexts.
-
Can this conversion be used for all types of solutions?
-
It is best suited for dilute aqueous solutions or wastewater effluents and assumes uniform mass distribution within the volumes.
Key Terminology
-
Pound/gallon (US)
-
A unit expressing the mass in pounds contained in one US liquid gallon of solution, used for concentration or density.
-
Pound/million gallon (US)
-
A concentration unit indicating one pound of substance distributed in one million US gallons, used for low pollutant levels.
-
Concentration
-
The amount of a substance (mass) present in a given volume of solution.
