What Is This Tool?

This converter transforms concentration measurements expressed in pound per million gallon (US) into pound per gallon (UK). It is useful for comparing low pollutant concentrations between US water treatment standards and UK or Commonwealth industrial specifications.

How to Use This Tool?

  • Enter the concentration value in pound per million gallon (US).
  • Select pound/gallon (UK) as the target unit.
  • Click convert to get the equivalent concentration in pound/gallon (UK).
  • Use the results to compare or report concentrations across different measurement systems.

Key Features

  • Converts concentration units used in water and wastewater engineering.
  • Facilitates translation between US and UK measurement conventions.
  • Supports low-level pollutant concentration values.
  • Ideal for regulatory compliance and industrial reporting.
  • Browser-based and easy to use with no installation required.

Examples

  • 10 pound/million gallon (US) equals 0.0000120095 pound/gallon (UK).
  • 100 pound/million gallon (US) equals 0.000120095 pound/gallon (UK).

Common Use Cases

  • Translating low-level pollutant concentrations for US water and wastewater engineering into UK imperial units.
  • Aligning industrial specifications between US and UK or Commonwealth systems.
  • Reporting treatment plant performance and regulatory compliance involving nutrients or contaminants.
  • Comparing chemical concentrations in agriculture and chemical manufacturing.

Tips & Best Practices

  • Ensure correct unit selection to avoid conversion errors between US and UK gallons.
  • Use the tool for low concentration values as it is tailored for dilute solutions.
  • Apply appropriate precision due to the small conversion factor involved.
  • Verify results in the context of regulatory or industrial standards.

Limitations

  • Conversion factor is very small, requiring careful attention to precision.
  • Differences in gallon definitions (US vs. UK) can lead to misinterpretation if not managed properly.
  • Primarily intended for dilute solutions; may not suit highly concentrated mixtures without adjustments.

Frequently Asked Questions

What does pound/million gallon (US) represent?
It is a concentration unit indicating one avoirdupois pound of substance in one million US gallons of water, often used for very low pollutant levels.

When should I use pound/gallon (UK)?
Pound/gallon (UK) is used mainly in older UK or Commonwealth industrial contexts to express solution concentration per imperial gallon.

Why is the conversion factor so small?
Because pound/million gallon (US) measures very diluted concentrations, converting to pound/gallon (UK) results in a very small numerical value.

Key Terminology

Pound/million gallon (US)
A concentration unit representing one avoirdupois pound of substance per one million US gallons of water.
Pound/gallon (UK)
A mass concentration unit indicating the amount of substance in avoirdupois pounds per imperial UK gallon of solution.
Conversion factor
The numerical value used to translate a measurement from one unit to another.
