What does grain/gallon (US) measure?

It measures density as the mass of one grain per U.S. liquid gallon, commonly used to indicate water hardness or mineral concentrations.

Why convert grain/gallon to gram/cubic meter?

To translate traditional U.S. customary measurements into metric units for scientific and engineering use, enabling standardized reporting and regulatory compliance.

Can temperature affect this unit conversion?

Yes, because volume can change with temperature and pressure, which may require corrections for precise density measurements.
