What does part per million (ppm) represent in concentration measurements?

Part per million (ppm) is a dimensionless unit denoting one part solute per one million parts of solution, often used as a mass fraction for very dilute concentrations.

Why convert ppm to pound per cubic foot (lb/ft^3)?

Converting to lb/ft^3 allows expressing trace chemical concentrations in mass per volume units, facilitating comparisons with fluid density or bulk material density.

Can this conversion be used for all types of solutions?

This conversion is best for uniform and dilute solutions; it may be less accurate for concentrated or non-homogeneous mixtures.
