What does grain/gallon (US) represent?

Grain/gallon (US) is a unit of density that measures mass per volume, equaling one grain (64.79891 milligrams) per U.S. liquid gallon (3.785411784 liters). It is often used to express water hardness.

Why convert grain/gallon (US) to milligram/liter?

Converting to milligram/liter allows users to work with metric units commonly used in environmental monitoring, laboratory analysis, and compliance reporting.

Is the conversion valid for all types of solutions?

The conversion is intended for dilute aqueous solutions where density differences are minimal and may not be accurate for more concentrated or non-aqueous mixtures.
