What is kilogram per cubic meter used for?

Kilogram per cubic meter is the SI derived unit of mass density used to quantify mass per unit volume in solids, liquids, and gases, commonly applied in scientific and engineering calculations such as fluid mechanics and material selection.

Why convert kg/m³ to grain per gallon (US)?

This conversion helps translate metric density values into a customary unit widely employed in water chemistry to measure hardness and mineral concentrations, facilitating regulatory compliance and practical use in water treatment.

Is grain per gallon (US) suitable for all density measurements?

No, it is primarily used in water chemistry contexts and may not be suitable for general density measurements outside this field due to variations in conditions and unit definitions.
